Framework for Monitoring the Effectiveness of Forest Habitat Management for Mountain Caribou DRAFT Version 1.1 Prepared for: Ministry of Forest and Range, Forest Practices Branch 272 Fisgard Street Victoria, BC V8W 1R8 Prepared by: Christoph Steeger, R.P. Bio. Pandion Ecological Research Ltd. 532 Park Street, Nelson, BC V1L 2G9 & Steven F. Wilson, R.P. Bio. EcoLogic Research 406 Hemlock Avenue, Gabriola Island, BC V0R 1X1 July 2006 Draft Effectiveness Monitoring Framework for Mountain Caribou Version 1.1 July 2006 Executive Summary The mountain caribou, Rangifer tarandus caribou, is an ecotype of the woodland caribou subspecies that almost exclusively resides in the mountainous region of south-central British Columbia. In recent years, provincial mountain caribou populations have declined dramatically, partly due to a number of factors resulting from human-related activities within their range, including habitat loss from forest harvesting, displacement by motorized recreation, increasing predation due to changes in the predator-prey system, and other threats and stressors that effect their populations and habitats (e.g., historic hunting, road-kill and possibly climate change). In response to the continuing decline and threats to the remaining subpopulations, the provincial and federal governments have listed mountain caribou as endangered (by the BC Conservation Data Centre) and threatened (by the Species at Risk Act), respectively. Currently, the BC Species at Risk Coordination Office is in the process of developing recovery options and related management actions for mountain caribou. Currently, management direction for mountain caribou is provided through approved regional Higher Level Plans and Land and Resource Management Plans and through provisions under the provincial Forest and Range Practices Act (FRPA) and interagency agreements. Since the adoption of a results-based forest practices regime in association with FRPA, land management measures are now implemented under an adaptive management principle which requires monitoring and evaluation of management results and subsequent verification or modification of management measures, where appropriate. To this end, the Ministry of Forests and Range, in partnership with the Ministry of Environment, established the FRPA Resource Evaluation Program. The program is a long-term commitment by government to evaluate the effectiveness of FRPA in achieving the stewardship of identified resource values, in this case mountain caribou. The monitoring approach for conducting these evaluations includes developing key monitoring objectives, questions, indicators and monitoring protocols. This monitoring framework represents the first step in the development of a comprehensive effectiveness monitoring methodology to assess the effectiveness of FRPA polices, practices and legislation pertaining to the management of mountain caribou habitat. Our focus at this stage is on identifying monitoring questions and indicators. We address the essential ecological characteristics of, and current threats to, caribou habitat in relation to the support that Ungulate Winter Ranges and Wildlife Habitat Areas may provide in maintaining caribou habitat across the forest landscape. We also include identification of knowledge gaps, potential methods for monitoring indicators at different spatial scales, and recommendation for habitat management activities.

Technical input and advise was also provided by Rodger Stewart (Ministry of Environment, Williams Lake), and Jeff Hoyt (Ministry of Environment, Victoria).Introduction The caribou species, Rangifer tarandus, consists of several subspecies, including the woodland caribou (R. t. caribou) whose range includes British Columbia. The mountain caribou, the focus of this effectiveness monitoring framework, is an ecotype of the woodland caribou that inhabits mountainous terrain of southeastern and central British Columbia. In recent decades, the remaining subpopulations of mountain caribou have experienced declines in distribution and abundance, triggering concerns about their conservation (review in MCTAC 2002). Population recovery efforts are currently underway to ensure the persistence of the woodland caribou in British Columbia (SaRCO 2005). Aside from recovery efforts, management direction for mountain caribou is provided through approved regional Higher Level Plans and Land and Resource Management Plans, provisions under the provincial Forest and Range Practices Act (FRPA), and interagency agreements (e.g., August 2003 UWR Memorandum of Understanding between the Ministry of Environment, Lands and Parks, Ministry of Forests, and Ministry of Sustainable Resource Management and the Identified Wildlife Management Strategy - IWMS). In some portions of the province, Wildlife Habitat Areas (WHAs) and Ungulate Winter Ranges (UWRs) have been established to protect important caribou habitat under the FRPA and Government Actions Regulations. In other areas, Forest Planning and Practices Regulation (FPPR) Section 7 Notices were issued by government that requires the Holder of an Forest Stewardship Plan (FSP) to specify a Result or Strategy to meet the Objective outlined in the Notice. FSP Holders may become exempt from the Notice if the objective is addressed by a WHA, UWR, General Wildlife Measure (GWM) or Wildlife Habitat Feature (WHF); however WHF are generally focused on specific habitat elements (i.e., nest trees, dens) and therefore do not generally address the broader landscape habitat requirements of caribou. FPPR Section 7 Species at Risk Notices for mountain caribou have been issued in the Prince George and Headwaters Forest Districts and as an UWR Notice in the Morice Timber Supply Area (TSA). There are also two mountain caribou UWRs in the Omenica Region and 30 WHAs in the Cariboo Region approved for mountain caribou through government orders. In addition, the Kootenay-Boundary HLPO, Revelstoke Minister Advisory Committee plan, LRMPs in Prince George, Robson Valley, Kamloops, Okanagan-Shuswap and the Cariboo-Chilcotin LUP outline plan-specific management strategies for mountain caribou. Since the adoption of a results-based forest practices regime in association with FRPA, land management measures are now implemented under an adaptive management principle which requires monitoring and evaluation of management results and subsequent verification or modification of management measures, where appropriate. To this end, the Ministry of Forests and Range, in partnership with the Ministry of Environment, established the FRPA Resource Pandion Ecological Research Ltd. Page 5 Draft Effectiveness Monitoring Framework for Mountain Caribou Version 1.1 July 2006 Evaluation Program which “works to assess the effectiveness of various management activities at maintaining biodiversity through the development of a program to address specific questions (objectives) and associated indicators” (Ministry of Forests and Range 2006). “One objective of this program is to develop monitoring approaches and tools for evaluating the effectiveness of management practices directed at managing wildlife. The monitoring approach for conducting these evaluations includes developing key monitoring objectives, questions, indicators and monitoring protocols for testing in pilot projects” (Erickson et al. 2005). This monitoring framework represents the first step in the development of a comprehensive effectiveness monitoring methodology for the management of mountain caribou habitat. Our focus at this stage is on identifying monitoring questions and indicators. We primarily address the essential ecological characteristics of, and current threats to, caribou habitat, and the roles that UWRs and WHAs play in maintaining caribou habitat across the landscape. We also address Higher Level Plan provisions that apply to habitat management for mountain caribou. Objectives The objectives of this project were to: 1. Review information on conservation status and habitat requirements of mountain caribou; 2. Describe natural and human-related stressors that potentially affect mountain caribou populations; 3. Identify key effectiveness monitoring questions related to the development of the monitoring frameworks; 4. Identify effectiveness indicators for the habitat, demographics and conservation of mountain caribou; and 5. Identify knowledge gaps and provide recommendations with respect to FRPA land use planning, habitat conservation/management and associated effectiveness monitoring for mountain caribou. Approach In developing this monitoring framework, we considered the approach outlined by the FRPA Evaluation Program (Province of BC 2004, Erickson et al. 2005) and included the following steps: 1. Summary of conservation status and situation analysis; 2. Identification of habitats and habitat attributes that are critical for meeting the life requisites of mountain caribou; 3. Description of habitat management tools for caribou currently applied under FRPA and higher level plans; Pandion Ecological Research Ltd. Page 6 Draft Effectiveness Monitoring Framework for Mountain Caribou Version 1.1 July 2006 4. Development of key monitoring questions at small, medium and large spatial scales; 5. Summary of population and habitat monitoring methods; 6. Selection of indicators based on criteria that address (i) different levels of monitoring intensity, (ii) desired outcomes in relation to the recovery goals set by the Province (SaRCO 2005); and (iii) required frequency of measurements; 7. Identification of knowledge gaps; and 8. Recommendations for implementing an effectiveness monitoring program for mountain caribou. Conservation Status & Situation Analysis Conservation Status and Demography In 1993, the BC Conservation Data Centre (CDC) placed mountain caribou on the provincial Blue List (vulnerable or sensitive status). In 2000, the CDC raised this taxon to the Red List (threatened or endangered status) because of continued declines in abundance and current threats. In May 2002, the National Committee on the Status of Endangered Wildlife in Canada (COSEWIC) designated the Southern Mountains National Ecological Area (SMNEA) population of the woodland caribou as threatened. The population is currently listed on Schedule 1 of the federal Species at Risk Act (SARA). Due to these status designations, a National Recovery Plan for woodland caribou is being developed under the requirements of SARA. National recovery plans consist of two parts: a national recovery strategy and local, population-specific recovery action plans. A"Strategy for the Recovery of Mountain Caribou in British Columbia" (MCTAC 2002) provides an evaluation of population status and recovery goals and objectives at the provincial level. At the regional level, three local recovery action plans have also been drafted for subpopulations inhabiting the North Kootenays (Hamilton et al. 2003), South Kootenays (Steeger et al. 2003) and Hart and Cariboo Mountains (Recovery Implementation Group 2004). Mountain caribou are one of three priority taxa involving recovery planning responsibility of the newly formed provincial Species at Risk Coordination Office (SaRCO). MCTAC (2002) recognized 13 subpopulations of mountain caribou BC, with an estimated total population of about 1700 animals. Six of these subpopulations now consist of 50 or fewer individuals and all populations, with the exception of the Hart Ranges subpopulation, are currently declining (SaRCO 2005). The current provincial mountain caribou metapopulation is estimated to be approximately 1900 animals (Hatter in review). The range and general abundance of mountain caribou is shown in Figure 1. Mountain caribou likely ranged south through forested portion of Idaho and west of the continental divide in Montana. Their range likely also extended farther west into the Okanagan Highlands Currently, their range is largely fragmented at its southern limits but more continuous in the north (SARCO 2005). Pandion Ecological Research Ltd. Page 7 Draft Effectiveness Monitoring Framework for Mountain Caribou Version 1.1 July 2006 Figure 1. Estimated historic range and current home range of mountain caribou populations in British Columbia (SARCO 2005). Life History & Habitat Use In this section we focus on the life history traits and habitat use of mountain caribou. We also emphasizes behavioural aspects that are most affected by the main stressors to individuals and populations. Food habits - The winter food habits of mountain caribou are unique in the deer family in that their foraging during late winter is limited almost exclusively to arboreal lichens (Alectoria sarmentosa and Bryoria spp.). During early winter, falsebox (Pachistima myrsinites) and arboreal lichen (found on broken branches and blowdown) are important ground food sources. Other shrubs such as willows (Salix spp.) and Vaccinium spp. may be used during early winter, but to a lesser extent. During other the seasons, mountain caribou feed extensively on a variety of foods including grasses, sedges, horsetails, flowering plants and leaves of numerous shrubs (MCTAC 2002 and references therein). Predation – The main predators of mountain caribou are grey wolf (Canis lupus), grizzly bear (Ursus arctos), black bear (U. americanus), cougar (Puma concolor), and wolverine (Gulo gulo) (Thomas and Gray 2002, Kinley and Apps 2001, Seip and Cichowski 1996). The anti-predator strategies or adaptations of mountain caribou include maintaining spatial segregation from other ungulate species and their predators in high-elevation forest patches, their unique adaptations to deep snow conditions, and their general use of habitats that are usually avoided by predators (e.g., Bergerud et al. 1984, Seip 1992). Pandion Ecological Research Ltd. Page 8 Draft Effectiveness Monitoring Framework for Mountain Caribou Version 1.1 July 2006 Home range and seasonal movement patterns - Minimum convex polygon home ranges of 150–600 km2 are typical for mountain caribou, but vary from <100 to >800 km2 (Cichowski et al. 2004). Within their range, mountain caribou activity is mainly concentrated in high elevation forests at approximately 1500 - 2100 m; however, elevation shifts are common but vary by local population, year, season and individual. During late winter, mountain caribou prefer open forest stands of the ESSF (Engelmann Spruce-Subalpine Fir) and ATp (Alpine Tundra parkland) ecosystem where they feed exclusively on arboreal lichen and are relatively safe from predators. In spring, lower elevation, early snow-free areas are sought but by June the pregnant females migrate to higher elevations, in search of safety found in often exposed and rugged areas to calve. Summer and fall habitat consists primarily of upper ESSF and ATp ecosystems, although lower ESSF habitats are used periodically. Early winter movements to lower ESSF and ICH (Interior Cedar Hemlock) forests are common while snow at higher elevations is accumulating but remains unconsolidated. Snow accumulation and snow consolidation are needed to elevate and enable the animals to reach and feed on the hair lichens in the trees. Lichens are typically absent from the lowermost branches (between 1.5m to 2.5m above the ground) due primarily to physiological sensitivity to prolonged exposure to snow (Goward 1998). Important habitats and habitat elements – Mountain caribou habitat requires consideration at the landscape scale (distribution in relatively low numbers over large areas), forest stand (forest structure, canopy openings, snow interception) and individual tree (patchiness, clumps of trees, foliated and defoliated branches). At the landscape scale, mountain caribou require large, contiguous patches of mature/old forests, preferably on moderate to gentle slopes, to provide cover and feeding habitat and to ensure spatial segregation from predators during all seasons. Forested ridgelines provide migration corridos between seasonal habitats. Undisturbed high-elevation, forested habitats are also used as late winter and calving ranges. At the scale of forest stands or specific sites, habitat elements most important for meeting the caribou’s life requisites include forest stand structure and habitat elements that support abundant arboreal lichens for early and late winter foraging, lush and succulent forage sites for feeding in early spring and mineral licks during spring (Cichowski et al. 2004). Hot springs are used as mineral licks by caribou throughout the year (D. Hamilton, pers. comm.). Population & Habitat Threats Major threats to the habitat and subpopulations of mountain caribou include both natural and human-related factors, as well as the interactions among them. Most relevant to this monitoring framework are those threats that are created as a result to the activities of forest and range developments under FRPA; that is, those activities that affect the important habitats and habitat elements of mountain caribou. Other threats (e.g., hydro-electric developments, linear corridors created by highways, railways, or pipelines, natural high mortality and low fecundity, past overhunting, and unfavourable climatic conditions) are likely cumulative to those posed by forestry activities. The following provides a summary of the main threats that have been identified to date. Forestry – Forest harvesting and silviculture activities and associated infrastructure have several effects on mountain caribou and their habitat: Reduction in the amount of foraging habitat (i.e., lichen) - It is believed that, in general, this habitat change does not have a strong effect on food availability for the small caribou herds currently present in the BC landscape (SaRCO 2005). However, both small and larger herds may experience increased need to travel among patches, thereby increasing energy expenditure and exposure to predators, humans, and avalanche-prone areas that may lead to increased mortality. While some of the current herds may still have sufficient lichen Pandion Ecological Research Ltd. Page 9 Draft Effectiveness Monitoring Framework for Mountain Caribou Version 1.1 July 2006 resources, it is questionable whether future lichen supply (that primarily exists in mature and old forests) will be sufficient for the increased herd sizes required to achieve selfsustaining populations. Increased populations of primary prey and associated predation pressures in caribou habitat – Evidence suggests that conversion of old forest to regenerating stands has increased caribou mortality through natural predation (Wittmer et al. 2005). Due to the increased abundance of high-elevation cutblocks, ungulate species such as deer, elk, and moose experience increased habitat suitability in caribou habitats, thereby drawing predators into these areas where they incidentally prey on caribou. A second factor may be the high productivity of other ungulates and their predators in low elevation habitats, which has been facilitated through landscape changes (e.g., agriculture) and wildlife and habitat management policies. Predators experiencing high population levels at lower elevations may spread into caribou habitat. It is likely that both high and lower elevation habitat changes are indirectly increasing predation pressures on mountain caribou. Logging roads and other linear corridors – This habitat change has been shown to increase predation on caribou in other areas by facilitating predator access (e.g., James and StuartSmith 2000, Dyer et al. 2002). Roads and linear corridors also facilitate human access into high-elevation habitats, leading to higher levels of disturbance and displacement of caribou from preferred patches (CCLUP Caribou Strategy Committee 2000, Appendix 6 and references therein). Commercial Recreation Tenures – Evidence suggests that motorized winter recreation activities such as snowmobiling, heli-skiing, and snowcat skiing can disturb caribou (Kinley 2003, Wilson & Hamilton 2003, Powell et al. 2004). When these activities are conducted via commercial enterprises, they become systematic, usually wide-spread, and potentially high-volume activities (Kinley 2003). Non-motorized commercial activities (e.g., ski-touring, hiking, mountain biking) may have less disturbance impacts on caribou; although evidence is scarce with respects to such activities. Non-commercial Recreation – The popularity of backcountry snowmobiling and ski-touring has generally increased among the public in recent years. This trend may have become another factor in the decline of caribou populations, although available evidence of long-term disturbance and/or displacement of caribou is more anecdotal and qualitative rather than supported by quantitative statistics. Predation – Predation has been shown to be the main proximate cause of the recent decline of caribou (Wittmer et al. 2005). However, it is unclear how various factors have interacted to lead to predation rates that are sufficiently high to cause population declines. The predator-prey system within and adjacent to mountain caribou habitat includes several ungulate and predator species and is naturally complex and dynamic. Human-caused changes to this system have been equally complex, including both changes to habitat conditions in and adjacent to caribou range, as well as direct changes to predator and prey populations through hunting management. Human-Caused Mortality – Human-related factors known to cause direct caribou mortality include accidental hunting (legal hunting was stopped province-wide in 1998), poaching, and road kill. Historically, mountain caribou were likely over-hunted (SaRCO 2005). Population Size and Isolation – Some mountain caribou subpopulations (e.g., South Selkirks, South Purcells, Monashee) are so small (< 50 animals) and/or isolated from the larger metapopulation (by large distances or semi-permeable barriers such as highways and hydro-electric reservoirs) that their Pandion Ecological Research Ltd. Page 10 Draft Effectiveness Monitoring Framework for Mountain Caribou Version 1.1 July 2006 viability is now threatened by factors such as population isolation, loss of genetic variability and stochastic events. Other threats which are more difficult to predict and quantify include climate change (e.g., less or more variable snow pack in caribou winter range), wildfires (which may become more catastrophic as systematic fire suppression increases fuel loads across the landscape), and insect (e.g., bark beetle) epidemics. While such stressors may negatively affect caribou over time, it is forest harvesting that is currently of particular concern because it affects habitat suitability both directly through removal and fragmentation of late-seral forests (including timber salvage operations) and indirectly through facilitating increased predation and human-caused disturbance. In summary, the factors associated with the threats to the subpopulations’ habitat, as described by SaRCO (2005), are: Demography Subpopulation size (probability of extirpation due to stochastic events, genetic factors, etc.) Isolation (due to distances) from other subpopulations Habitat (Direct) Winter forage (arboreal lichen) availability Non-winter forage availability Calving areas availability Habitat (Indirect) Extent of range (for predator avoidance) Fragmentation (reduced range effectiveness) Isolation (due to poor habitat) from other subpopulations Suitability for alternative prey within and near caribou range Predation (Direct) Predator species and density within ranges that overlap caribou Predation (Indirect) Alternate prey densities within and adjacent to caribou range Disturbance (Direct) Human-caused mortalities (collisions, poaching) Disturbance (Indirect) Displacement from preferred habitats by commercial tenured recreation (heliskiing, snowcats, snowmobiles) Displacement from preferred habitats by recreationists (principally snowmobiles but also expanding summer activities such as heli-hiking/biking and high-elevation all-terrain vehicle use) These factors pose varying degrees of potential risk to the viability of subpopulations and have different ease of mitigation associated with them. How they relate to the establishment of UWRs and WHAs is discussed below. Pandion Ecological Research Ltd. Page 11 Draft Effectiveness Monitoring Framework for Mountain Caribou Version 1.1 July 2006 Habitat Management & Recovery Planning Habitat management – Prior to recovery planning, mountain caribou habitat was managed primarily through the provincial laws and regulations, policies, and guidelines set by government. Caribou habitat mapping and management objectives have been implemented via regional Land & Resource Management Plans and Land Use Plans and primarily involved maintaining networks of “core areas” (areas of no timber harvest to maintain arboreal lichens and limit access), “caribou management emphasis” and/or “buffer zones” around core areas, including areas of selection logging and extended rotations, and sometimes “linkages” or movement corridors between core areas. In some cases, caribou habitat management prescriptions included a high-elevation noharvest zone, which, in most areas, corresponded approximately to the forest harvesting “operability line” (Simpson et al. 1997). Recovery Planning – Following the 2002 COSEWIC designation of “threatened” status for the woodland caribou in the Southern Mountains National Ecological Area, a strategy for the recovery of mountain caribou was released by the Province (MCTAC 2002). Several local recovery action/implementation groups were also established in the South Kootenay, North Kootenay, and Cariboo and Hart Mountains (see above). These planning efforts coincided with significant declines in the southernmost mountain caribou populations. Subsequently, the Forest Practices Board of BC released a special report in September 2004 emphasizing the urgent need to launch into a concerted recovery initiative, to prevent further declines of mountain caribou populations (Forest Practice Board 2004). One consequence of this report was the establishment of the BC Species at Risk Coordination Office and the subsequent provincially-led recovery planning effort. Statutory Authority Higher Level Plans (HLPs) are government-approved regional plans that contain legislated requirements for management of specific resource values, such as mountain caribou. The caribou component of these plans are the negotiated result of public process. Land Use Plans (LUPs) are strategic regional planning tools that set broad objectives for different zones with respect to habitat protection and management as well as resource development options. Some LUPs contain spatially-explicit objectives while others are qualitative and as yet non-spatial. Approved LUPs take precedence over other resource objectives. Not all current LUPs have been approved as Higher Level Plans and therefore do not contain legislated requirements. Land and Resource Management Plans (LRMPs) are sub-regional integrated resource plans, designed to create a vision for use and management of public provincial lands and resources. LRMPs also contain spatially-explicit, broad land use zones, objectives that guide management of natural resources in each zone, and strategies for achieving the objectives. Most provisions in LRMPs are not legislated requirements but rather policy direction. Several LUPs and LRMPs exist that include objectives and management prescriptions for mountain caribou (Table 1). While the general approach is similar among regions, the plans differ with respect to their stage of completion and official approval. Those management directions that have legal status within Higher Level Plans maintain this status under FRPA while policy directions and guidelines are to be considered in Forest Stewardship Plans, at which time they become legal requirements.

Okanagan-Shuswap Identifies OGMAs to be maintained as reserves and also identifies research areas, which may later become reserves, conventional harvest areas, or modified-harvest areas, pending research results. Revelstoke No harvest zones and modified harvest zones, each of which is mapped but not approved. Forest and Range Practices Act (FRPA) – Under Section 149 of the FRPA, the Lieutenant Governor in Council may make regulations prescribing objectives for a number of resource values (e.g., wildlife). Under Section 149.1, the Lieutenant Governor may make regulations authorizing the Minister of Environment to establish UWR and WHA objectives and GWM applied thereto. Forest Planning and Practices Regulations (FPPR) – Under Section 7 of the FPPR, a Notice can be issued by government that require the Holder of a Forest Stewardship Plan (FSP) to develop and incorporate into their FSP specific measurable or verifiable operational Results (i.e., outcomes) or Strategies (i.e., practices) for management of amount and distribution of habitat required for a specified ungulate winter range or species at risk. Specific habitat requirements and habitat areas are part of the Notice itself, and often accompanied by reference to the IWMS or additional supporting information provided by the Ministry of Environment. Section 7 Notices are not issued in areas where caribou management falls under approved HLPs and eligibility for FSP Holder exemptions may occur through the establishment of a WHA, GWM, and/or WHF. Government Actions Regulation (GAR) – Under Section 10(1) of the GAR, the minister responsible for the Wildlife Act may establish by order an area as a WHA and set objectives for species at risk or regionally important wildlife. The minister may also identify a localized WHF to which special forest or range management practices are applied that have not been otherwise provided for under GAR or another enactment. Identified Wildlife Management Strategy – The IWMS is an initiative by the Ministry of Environment in partnership with the Ministry of Forests that provides direction, policy, procedures and guidelines for managing Identified Wildlife. The goals of the IWMS are to minimize the effects Pandion Ecological Research Ltd. Page 13 Draft Effectiveness Monitoring Framework for Mountain Caribou Version 1.1 July 2006 of forest and range practices on Identified Wildlife found on Crown land and to maintain their limiting habitats throughout their current ranges and, where appropriate, their historic ranges. In some cases, this will require restoration of previously occupied habitats, particularly for those species most at risk. Identified Wildlife are managed through the establishment of Wildlife Habitat Areas and the implementation of General Wildlife Measures (GWMs) and Wildlife Habitat Area objectives, or through other management practices specified in strategic or landscape level plans (Ministry of Environment 2006b). The term Identified Wildlife refers to those Species at Risk and Regionally Important Wildlife that the Minister of Environment designates as requiring special management attention under FRPA. Species at Risk includes endangered, threatened, or vulnerable species of vertebrates and invertebrates, and endangered or threatened plants and plant communities that are negatively affected by forest or range management on Crown land and are not adequately protected by other mechanisms. Regionally Important Wildlife includes species that are considered important to a region of British Columbia, rely on habitats that are not otherwise protected under FRPA and may be adversely impacted by forest or range practices. Statutory authority for the IWMS is provided under provisions of the Forest Practices Code of British Columbia Act and Regulations and under the Forest Range and Practices Act and Regulations. Two companion documents address the management of Identified Wildlife: (i) Procedures for Managing Identified Wildlife describe the procedures for establishing, modifying or rescinding a WHA, and for implementing strategic and landscape planning recommendations and (ii) Accounts and Measures for Managing Identified Wildlife summarizes the life history, distribution, habitat and status of Identified Wildlife, including specific habitat management guidelines. Implementation of the IWMS, including establishment of WHAs and GWMs, must be consistent with existing higher-level plans or sustainable resource management plans and within policy limits for timber supply impacts. In summary, the types of legislated measures that currently exist in BC to protect and manage mountain caribou habitat are: Ungulate Winter Ranges, Wildlife Habitat Areas, and some parts of regional Land Use Plans and Land & Resource Management Plans. In addition (but de-emphasized in this monitoring framework) are provisions under the provincial Wildlife Act that allow for vehicular access and area closures in important wildlife habitats and, through a recent amendment, designations of a “residence” for a species-at-risk. Ungulate Winter Ranges UWR management has been ongoing for over 20 years in some portions of the province. Formal legal establishment of UWRs and associated objectives began under the Forest Practices Code and continues under FRPA. An UWR is defined as an “area that contains habitat that is necessary to meet the winter habitat requirements of an ungulate species”. UWRs are based on our current understanding of ungulate winter habitat requirements, as interpreted by the Ministry of Environment (MOE) regional staff from current scientific and management literature, local knowledge, and other local expertise. Sections 7, 10 and 11 of the Government Actions Regulation (BC Reg. 17/04) of the FRPA describe the formal legislative basis for establishing UWR” (Ministry of Environment 2006a). Currently, two approved mountain caribou UWR have been established for the Hart Ranges subpopulation (Appendix 2; http://www.env.gov.bc.ca/wld/uwr/ungulate_app.html): Omineca Pandion Ecological Research Ltd. Page 14 Draft Effectiveness Monitoring Framework for Mountain Caribou Version 1.1 July 2006 Region UWR ID U-7-001 (Kennedy Siding; Mackenzie Forest District) and UWR ID U-7-003 (Omineca; Fort St. James, Prince George, and Headwaters Forest Districts), which are 2,893 ha and 803,306 ha in size, respectively. Both of these UWR were established in 2003. The management objectives for U-7-001 are: prevention or avoidance of predation, maintenance of habitat conditions, minimization of disturbance to caribou and their food resources, access management, and reduction or prevention of conflicts between caribou and livestock. The management objectives for U-7-003 are: maintenance of caribou habitat corridors, maintenance of old forests that provide arboreal lichens in high suitability habitat, and maintenance of habitat values in medium suitability habitat. The intention of establishing UWR is to provide suitable habitat for ungulates during the season most demanding on the animals’ physical condition. While the elevation of suitable winter range does not differ much during winter seasons for most ungulates, there may be considerable differences between early and late winter ranges for mountain caribou. During early winter, caribou often descend to lower elevation ICH and ICH/ESSF transition forests in response to deep, soft snow conditions at higher elevations that create poor mobility and limit food availability. The animals will remain at lower elevations, often in close proximity to other winter ungulates and their predators, until snow depths accumulate and consolidate sufficiently to enable the animals to reascend to late-winter upper ESSF and ATp forested parkland habitats. The late winter habitat only becomes usable when the appropriate snow conditions allow the animals to walk on the snow surface and be lifted by the snow to reach the arboreal lichen food found only above the snowline on trees. Differences in elevation may span several hundred meters between November and March, usually between 1500 and 2000 m in the Cariboo Region (CCLUP Caribou Strategy Committee 2000 and references therein). These elevation shifts may differ among individuals, herds, and years, and primarily depend on the topography of their range and snow conditions and associated ease of movement and access to food (Seip 1990, Young and Roorda 2000). Effective UWR design for mountain caribou have to take such regional differences into account. Wildlife Habitat Areas Wildlife Habitat Areas (WHAs) are a component of the provincial IWMS and WHAs and WHA objectives can be established under regulations provided under FRPA and GAR. The document titled Accounts and Measures for Managing Identified Wildlife (Ministry of Environment 2004) contains an account for mountain caribou where the goal for WHAs and proposed GWMs are outlined. In some cases, because WHAs are being used to implement the intent of LUPs and LRMPs, the design and GWMs established for the WHAs may not necessarily reflect those outlined Pandion Ecological Research Ltd. Page 15 Draft Effectiveness Monitoring Framework for Mountain Caribou Version 1.1 July 2006 in the species account; rather, they may reflect language consistent with the direction of the LRMP or LUP. In all cases, the resulting protection should be the same (Jeff Hoyt, pers. comm.). Currently, 30 approved mountain caribou WHAs (WHAs #5-088 to 5-117) exist in BC (Appendix 3). These were established for the Wells Gray North, Wells Gray South, North Cariboo Mountains, and Barkerville subpopulations (http://www.env.gov.bc.ca/cgibin/apps/faw/wharesult.cgi?search=show_approved) and range from 51 – 62,669 ha in size. These WHAs were established in 2004 and the associated GWMs were established in 2005. The purpose of these GWMs is to maintain caribou habitat values within the polygons specified in the Order (Section 9(2) of the Government Actions Regulation (B.C. Reg. 582/2004), consistent with the Cariboo-Chilcotin Land Use Plan. The two main measures are (i) No Harvest in WHAs # 5-096 to 5-101, 5-106 to 5-108, 5-110, and 5-117 and (ii) Modified Harvest in WHAs 5-088 to 5095, 5-102 to 5-105, 5-109, 5-111 to 5-116. In the case of WHAs #5-088 to 5-117, the GWMs are not independent of the Cariboo-Chilcotin Land Use Plan, which called for an integrated approach to caribou habitat management with consideration of CCLUP timber targets, among other objectives (CCLUP Caribou Strategy Committee 2000 Appendix 1). The CCLUP Caribou Strategy Committee recognized that mountain caribou habitat and subpopulations can only be maintained if (i) suitable habitat is maintained within the populations range, (ii) road access and motorized recreation in caribou habitat is limited and regulated, and (iii) predation levels on caribou are managed. The Committee recommended a combination of “no harvest” and consolidated “modified harvest” areas and that the resulting large area of “modified harvest” between Cariboo Mountains Park and Quesnel Lake would “serve as the major test area to insure the ‘modified harvest’ prescription provides caribou habitat over the long term.” The confounding factor of motorized recreation was to be carefully regulated or eliminated, to ensure the potential success of this test. The methods recommended for the “modified harvest” areas was a combination of group and single-tree selection silvicultural system, with 33% timber removal every 80 years (CCLUP Caribou Strategy Committee 2000). The linked objectives of the CCLUP and the WHAs will need to be reflected in an effectiveness monitoring plan for these habitat management measures. With respect to management objectives in general, the principal difference between UWR and WHA is that the concern for UWR is limited to habitat conditions on winter range while that of the WHA addresses all life history requirements of the target species. Management prescriptions however do not differ much between the two management tools: both range from prohibiting further approval of harvesting and road building to modified harvesting prescriptions that include specifications of volume or area removal, rotation length, limits on opening sizes and patterns, forest health provisions and access limitations, among others. Although UWR is intended to address only habitat required for the winter survival of ungulates, the Omineca UWR 7-003 aside from winter range, includes caribou movement corridors, calving and rutting areas, and the forest matrix surrounding these habitat features. This is largely because the UWR was to capture the intent of the regional LRMP, which did not distinguish between winter habitat and other required habitat components. General Wildlife Measures currently apply to WHAs and the Ministry of Environment intends to replace objectives that were established for UWRs with GWMs in the near future (Jeff Hoyt, pers. comm.). The same sets of effectiveness monitoring questions and indicators can therefore be used for both types of habitat protection tools (see below). Pandion Ecological Research Ltd. Page 16 Draft Effectiveness Monitoring Framework for Mountain Caribou Version 1.1 July 2006 Relationship between FRPA / Higher Level Plan Habitat Management Tools & Recovery Planning / Implementation for Species at Risk Land management tools (UWR, WHA, GWM, WHF and HLP/LUP/LRMP objectives and forest management guidelines/strategies) available under the Forest Practices Code, FRPA, FPPR, GAR, approved HLPs, and the BC Land Act and Wildlife Act will likely be the primary tools by which recovery for mountain caribou will be implemented (Jeff Hoyt, Wayne Erickson, pers. comm.). Should government determine that these tools are not adequate to meet recovery goals and objectives for mountain caribou, then government could choose to alter policy and replace or amend regulations, accordingly. Monitoring the Effectiveness of Forest Management for Mountain Caribou How does effectiveness monitoring fit into the current situation of habitat management for mountain caribou? - The fact that most caribou subpopulations have been declining under current planning and management initiatives may be due, to some extent, to demographic factors and stressors not directly related to habitat management necessitates a two-pronged effectiveness monitoring approach that addresses: (i) the direct consequences of the prescribed forest practices with respect to landscape and stand composition, structure and function, and, (ii) the indirect consequences of the prescribed forest practices with respect to increased predation and humanrelated activity in the backcountry. In addition, the forthcoming mountain caribou recovery options and management actions may change the caribou habitat management regime, which could potentially confound the effects of the current set of FRPA and HLP-based management practices. The effectiveness monitoring indicators, described below are therefore preliminary and should be adjusted as caribou habitat management under different policy tools becomes more integrated. Key Effectiveness Monitoring Questions The following are key monitoring questions related to assessing the effectiveness of Ungulate Winter Ranges and Wildlife Habitat Areas established for mountain caribou under FRPA. We focus on UWRs and WHAs as these are the most relevant management tools under FRPA. Small Scale (Individual Ungulate Winter Ranges and Wildlife Habitat Areas) 1. Does the UWR/WHA provide the essential forest habitat structure and habitat elements for which it was established? 2. Is the UWR/WHA receiving sustained use by mountain caribou? 3. Are predation events occurring within the UWR/WHA? 4. Are human-related activities affecting use of the UWR/WHA by mountain caribou? Pandion Ecological Research Ltd. Page 17 Draft Effectiveness Monitoring Framework for Mountain Caribou Version 1.1 July 2006 Medium Scale (Mountain Caribou Subpopulation Level) 5. Is the distribution and abundance of individual UWR/WHA units in relation to other areas (e.g., protected areas, higher-level plan habitat objectives/practices) sufficient to sustain the amount and distribution of habitat for identified subpopulations of mountain caribou? 6. Are there barriers outside of the UWR/WHA that prevent or reduce use of WHA/UWR by caribou? Large Scale (Mountain Caribou Population) 7. Is the amount and distribution of UWR/WHA units in relation to other managed and unmanaged areas sufficient to allow regular movement of individuals between subpopulations, thereby ensuring the health of the meta-population? Effectiveness Indicators Indicators can measure the function (e.g., snow depth, forage accessibility), forest stand structure (e.g., forest canopy characteristics) or caribou use (e.g., direct inventory) of Ungulate Winter Ranges and Wildlife Habitat Areas. Indicators should be/have: Focused on specific evaluation question; Supported by scientific research and literature and/or peer reviewed; Available baseline data; Measurable (accuracy and precision); Cost-effective to monitor; and Sensitive to forest and range management or stressor change. Different indicators require different levels of resources to measure and monitor. Indicators can be broadly classified as: Routine: Generally measured through office procedures involving available data collected for other purposes (e.g., map interpretation); Extensive: Requires low-intensity qualitative or quantitative field assessments (e.g., wildfire assessments, habitat supply evaluation, forest structural conditions); and, Intensive: Requires detailed, quantitative fieldwork (e.g., population inventory, habitat attributes and elements). Assessing the effectiveness of forest habitat management at medium and large spatial scales requires evaluation in relation to broad management objectives: Population maintenance: Maintain the current habitat occupancy (medium scale) and abundance and distribution (large scale) of mountain caribou. Use currently occupied habitat and indices of abundance as the basis for defining desired forest habitat conditions. Note however that it will be difficult to relate abundance and distribution of caribou directly to the extent and condition of habitat as potentially confounding factors such as predation, displacement by humans, or stochastic events could mask any inferred causal Pandion Ecological Research Ltd. Page 18 Draft Effectiveness Monitoring Framework for Mountain Caribou Version 1.1 July 2006 relationships. Controlled management regimes such as in the indended Cariboo Mountains Park - Quesnel Lake test area (CCLUP Caribou Strategy Committee 2000) will be required to minimize non-forestry related factors. Population recovery: Increase rates of occupancy of suitable habitat and increase the abundance and possibly the regional distribution of mountain caribou. Use habitat capability and recovery objectives related to abundance and distribution as the basis for defining desired forest habitat conditions. Considering the current declining population trends, we anticipate that population recovery objectives will be emphasized in future management approaches. Recommended indicators and general methodological considerations are presented in Tables 2 and 3, respectively. Considerable differences exist in the amount of time and resources required to monitor these indicators and in the strength and conclusiveness of evidence they may provide related to the effectiveness of habitat management. As a result, adaptive management based on monitoring outcomes will require an assessment of general trends among a number of indicators, rather than on definitive cause-and-effect studies. Because the system is complex, professional judgement will be required to interpret ambivalent or contradictory evidence. Table 2.

Predation rates can only be determined with confidence through intensive monitoring of radio-collard individuals. Requires aerial surveys. Recommended by CCLUP Caribou Strategy. Requires regular aerial surveys or other assessment methods. High levels of compliance with regulations may require enforcement. Consider both winter and summer surveys. Tracking of radio-collared individuals. Habitat continuity, isolation, and fragmentation can be tracked and mapped through GIS. The amount of usable access roads can be tracked and mapped through GIS. Also track amount of road area (km) rehabilitated. Additional habitat will be required if population recovery rather than maintenance is an objective. In some areas, critical habitats are also found outside the Crown Forest Land Base on private land. Its contribution and security should be considered in the examination of this indicator. Comparison of both suitable and capable habitats for all seasons would be valuable. Involves a sufficient number of census flights to meet appropriate confidence levels in (sub)population estimates.

Many knowledge gaps related to the key monitoring questions are best addressed through adaptive management trials (Table 2). Filling some of the knowledge gaps may require long-term research or intensive monitoring projects. Table 4. Knowledge gaps related to mountain caribou ecology and relevant to the key effectiveness monitoring questions. Pandion Ecological Research Ltd. Page 21 Draft Effectiveness Monitoring Framework for Mountain Caribou Monitoring Question Version 1.1 July 2006 Knowledge Gaps Small Scale (Individual Ungulate Winter Ranges and Wildlife Habitat Areas) Does the UWR/WHA provide the habitat structure and elements required to fulfil the life requisites of wintering mountain caribou? - While essential habitat elements such as lichen and favourable forest structural conditions may be retained in selectively harvested stands, it is unclear how these stands affect caribou foraging efficiency and use. Is the UWR/WHA receiving sustained use by mountain caribou? - none Are predation events occurring within the UWR/WHA? - When predation occurs, the question remains whether altered caribou behaviour (e.g., increased movements into less suitable areas due to disturbance) or habitat changes (e.g., early-seral patches in caribou habitats attracting alternate prey and predators) are responsible for undesired predation rates. Is human-related disturbance affecting use of the UWR/WHA? - While evidence suggests that snowmobiles and helicopters can result in short-term changes to caribou behaviour, the magnitude of longer-term behavioural changes by caribou (e.g., permanent or semi-permanent range displacements, demographic effects) is less clear. Questions also remain regarding the impacts of snow-cat operations and non-motorized backcountry recreation, and the role of disturbance factors during non-winter seasons. Medium Scale (Watershed or Management Unit) Are caribou using the UWR/WHA identified as habitat corridors? - Since portions of established caribou corridors are part of managed landscapes, it is questionable whether caribou realize adequate foraging efficiencies and survival rates within these corridors. The combination of population censuses, groundbased track/use surveys and mortality assessments would increase knowledge of the effectiveness of corridors. Are caribou mixing among the regional subpopulations and is the health of the meta-population ensured? - Ultimately, isolation of herds or individual groups within a herd has to be eliminated and mixing of genes among subpopulations needs to occur to recover caribou populations. Documented mixing of herds would increase confidence that subpopulations are part of metapopulation dynamics. Are there barriers outside of the UWR/WHA that prevent or reduce the potential use of the UWR/WHA? - Analyses of the landscape surrounding UWR/WHA with respect to habitat suitability and barriers such as terrain ruggedness, roads, hydro, seismic or gas line corridors, and water reservoirs is needed to address the factors facilitating or preventing habitat use. Pandion Ecological Research Ltd. Page 22 Draft Effectiveness Monitoring Framework for Mountain Caribou Version 1.1 July 2006 Monitoring Question Knowledge Gaps Is the distribution and abundance of individual UWR/WHA units established for mountain caribou sufficient to ensure over-winter survival in typical and severe winters? - Relationship between habitat fragmentation and habitat effectiveness is poorly characterized. - How much of the landscape can be managed under ‘modified harvest’ without negatively affecting caribou is currently unknown. - Questions remain regarding the influence of snow conditions on seasonal elevation shifts of herds (CCPLU Caribou Strategy Committee 2000). Is the location of individual UWR/WHA units established for mountain caribou adequate to ensure successful calving events? - Surveys are required to locate a maximum of calving areas. Current calf survival rates need to be established. Additional measures to protect calving females are considered as part of recovery implementation (SaRCO 2005); any such new measures have to be considered in evaluating the effectiveness of UWR/WHA units. Has access management resulted in no-change or reduction of road densities in the UWR/WHA? - none Large Scale (Subregional or Regional Populations) Is the distribution and abundance of UWR/WHA established for mountain caribou sufficient to sustain/recover the regional subpopulations and meta-population? - Critical habitat identification and habitat suitability, population viability and other analyses are ongoing as part of recovery planning and need to be integrated with UWR and WHA management. Recommendations 1. The management objective of the UWRs is to maintain the caribou within the identified UWRs. Similarly, the expressed purpose of the General Wildlife Measures is to “maintain caribou habitat values within the polygons specified in the Order …” (Order – General Wildlife Measures; Wildlife Habitat Areas #5-088 to 5-117). However, the caribou subpopulations currently existing in BC are endangered and have shown dramatic recent declines in numbers. Some are considered to be below viable population size and require immediate recovery actions (SaRCO 2005). The management objectives, as described in the UWR and WHA orders, may not be sufficient on their own to maintain mountain caribou within the identified polygons. A comprehensive effectiveness monitoring program for caribou habitat management needs to address the broader context of FRPA-related management actions in relation to mountain caribou recovery planning and higher-level plan objectives. 2. We recommend an approach be developed that creates a clear distinction in the goals and objectives related to mountain caribou UWRs and WHAs and those of negotiated land use or resource management plans. We recommend a system which addresses all mountain Pandion Ecological Research Ltd. Page 23 Draft Effectiveness Monitoring Framework for Mountain Caribou Version 1.1 July 2006 caribou life requisites, including winter range requirements. Re-evaluating the concept of UWR for mountain caribou may be appropriate because (i) early and late winter range requirements may differ considerably among areas (depending on topography) and years (depending on snow conditions) and (ii) winter range requirements for caribou are different form those of the other ungulates. 3. Monitoring the effectiveness of UWR and WHA management for mountain caribou should involve the following components: Establishing subpopulation (recovery) targets through SaRCO, HLPs, or REP measures against predetermined baselines; Implementing procedures to collect, warehouse and analyze routine indicator data; Allocating resources to collect extensive indicator data in areas of greatest management concern; and, Collaborating with other agencies and researchers to collect intensive indicator data and to address knowledge gaps.
