HFQLG Monitoring Plan BMP Implementation and Effectiveness Monitoring Results (2007) Introduction: This report summarizes results of monitoring conducted to assess implementation and effectiveness of Best Management Practices employed to reduce risks to water quality on projects associated with HFLQG projects. The report includes data collected during 2007. Best Management Practices were monitored using the Pacific Southwest Region protocols (BMPEP). This approach requires activity sites to have undergone at least one winter prior to evaluation. Therefore, all sites monitored were implemented in 2006 or earlier. The protocol involves a two-step process. The first assesses implementation. A series of questions is answered to determine if measures to reduce risk to water quality were considered during project planning, design and layout, and if prescribed measures were implemented on the ground. The assessment of implementation is largely qualitative. It involves review of project documents and pertinent operational direction and guides, and comparison of planned (or mandated) actions with results implemented on the ground. The second step is an evaluation of practice effectiveness. This evaluation is conducted at the site of the practice, and is based on field review of indicators of processes that affect water quality. These focus primarily on erosion, and include criteria such as rilling, sediment deposition and sediment transport. The effectiveness evaluation is objective. Results from both implementation and effectiveness are summarized to yield a result of “implemented or not implemented” and “effective or not effective”. These results are generated by weighting the various evaluation criteria (those deemed most important receive higher weights) and comparing the resulting composite score against a pre-determined value that distinguishes scores as implemented or not implemented, and effective and not effective. In this report, results for individual criteria are discussed in addition to the composite scores. Sample Selection: Sites were randomly selected. Levels of targeted activities (harvesting, decommissioning, and burning) vary yearly on each of the districts and correspondingly the number of sites that can be included fluctuates between districts. Therefore, in any given year it may not appear there is a balanced sampling across the Pilot Project and this is acceptable. The entire Pilot Area is the basis for the monitoring – not the individual districts. For evaluation of streamside management (T01), skid trails (T02) and landings (T04), a pool of HFQLG units with RHCAs (the acronyms RHCA (Riparian Habitat Conservation Area) and SMZ (Streamside Management Zone) are used interchangeably) were identified, and served as the sample population. This was done to ensure that all three evaluations were located in the same place. Evaluations for roads (stream crossings, drainage and decommissioning) and HFQLG Best Management Practices Monitoring: Results 2007 1 prescribed burn sites had separate pools developed. These separate pools of sites were randomly sorted with a random number generator and the first 30 from each pool were selected. BMPs for Streamside Management Zones (SMZ), skidding, landings, road drainage and stream crossings evaluations were made in activity areas of the following projects: North Coble, Cabin, Jonesville DFPZ, Fox Farm DFPZ, Blacks Ridge, Railroad DFPZ, Beak DFPZ, Claw DFPZ, Bits DFPZ, Toe Service Contract, Pilot SBA, Deanes, and Guard, and Hungry project areas. Prescribed burn evaluations were conducted in: Buck, Red Clover, Green Flat, Hungry, Last Chance, Lower Slate, Strawberry Valley, Brush Cr., and Red Mtn. Arkansas, North Coble, Pittville, Camino, Toro, Zingira Underburn, Grays, North Crater West, Lost Lake, and Battle DFPZ project areas. Road decommissioning evaluations were conducted in: Last Chance, Crystal Adams, Toro, Vaca timber sale areas and the Cone Crater EA analysis area. Evaluations: BMP evaluations are usually conducted by resource specialists from each district. However, the Lassen NF chose to have this managed by the watershed staff out of the Supervisors office. Evaluations included assessments of practices associated with streamcourse protection (evaluation T01), skid trails (T02), landings (T04), road drainage (E08) and stream crossings (E09), prescribed fire (F25) and road decommissioning (E10). The number of evaluations and their distribution among the HFQLG administrative units are presented in Table 1.

Results Summary: HFQLG Best Management Practices Monitoring: Results 2007 2 Table 2 summarizes results from the BMPEP evaluations, based on the composite scores for implementation and effectiveness. Results are reported in four categories: IE (BMPs implemented and on-site objectives met), NIE (BMPs not implemented, but on site-objectives met), INE (BMPs implemented but not effective in meeting on-site objectives) and NINE (BMPs not implemented and objectives not met). Note: BMP evaluations employ direct observations of on-site factors that pose risks to water quality.

On average, these goals have been met. Areas where improvement can be realized include designing, building, and maintaining roads to withstand significant precipitation events. Several road fills evaluated this year had slope failures and rills which led to sediment deposition in drainage channels. Other than the noted problems at road/stream crossings, the results of this year’s monitoring efforts indicate that BMPs effectively reduced risk to water quality across the pilot project area. These issues are also discussed in the summary of individual evaluations. Effectiveness evaluations are based on objective review of activity areas that focus on indicators of processes of concern. In most cases, they represent a risk of water quality degradation, rather than actual degradation. In cases where effectiveness scores are low, observers are asked to comment on potential impacts to water quality, in terms of degree, duration and extent. For sites where effectiveness ratings were low, one third of the sites were in locations where a major storm event in January 2006 affected the road and crossing. Field observers indicated that the degree, duration, and extent to which water quality was affected would persist until the problems at these sites are addressed. For the remaining six sites, small amounts of sediment were seen where road surface maintenance had pushed that material into the channel at the crossings. These impacts were noted to be short in duration, minor in extent and easily corrected. A key effectiveness criterion relative to risks to water quality is evidence of sediment transport to a channel (Table 3). Of the 194 evaluations that included this criterion, sediment to a RHCA was found at 12 sites (6 percent), sediment to a channel was found at 11 sites (5.7 percent). At all but two prescribed burn locations, the sediment-filtering function of the RHCA was not even utilized. Locations where roads cross streams – where no protective buffer exists – constitute the majority of sediment-to-channel occurrences.

Evaluations with evidence of sediment delivery to RHCAs and channels. Results by Individual Evaluation T01- Streamcourse protection. Implementation- All sites had adequate implementation of SMZs Effectiveness- All sites effectively mitigated the risk to water quality. Recommendations: Continue to designate SMZs as areas of no treatment or carefully managed treatment. T02- Erosion Control on Skid Trails Implementation- All but 3 sites had adequate implementation of erosion control on skid trails. On these 3 sites, waterbars were either missing or inadequate. Effectiveness- All but one site was effectively protected from erosion. There was no sediment to channel evident at any of the sites evaluated. Recommendations: Administrators need to stay vigilant when checking quality of and location of erosion control measures, such as water bars. T04- Erosion Control on Landings Implementation- BMPs were implemented on all but one site. Effectiveness- No increased risks to water quality or increased erosion were noted at any of the sites evaluated this year HFQLG Best Management Practices Monitoring: Results 2007 4 Recommendations: Continue to locate landings outside of RHCAs. Replace ground cover on landings (with slash, mulch, etc.) when operations are complete in order to improve erosion control. E08- Roads Implementation- 40 out of 42 sites had BMPs implemented as prescribed. Effectiveness- Six sites on the Lassen had evidence of sediment to channel. Road surface maintenance pushed this material into the channels. Three of the six sites on the Plumas had evidence of sediment to channel. The Plumas sites all suffered damage in the January 2006 storm event. Recommendations: Road surface maintenance should be conducted as infrequently as possible at crossing locations. The blade can simply be raised as the grader passes over a crossing. Recent research indicates that surface blading at crossings is a primary cause of sediment deposition in channels. For sites that have been damaged in storm events, repair measures should be implemented as soon as possible. E09- Stream Crossings Implementation- 8 of 9 crossings had proper BMP implementation. Effectiveness- 4 of the 9 sites evaluated had problems at stream crossings, with sediment to channel evident. Recommendations: Stream crossings remain the primary source of increased risk to water quality on National Forest System lands. As stated in the discussion of E08 above, the road surface at crossings should be bladed infrequently. Also, crossings damaged by storm events should be repaired as soon as possible. Otherwise they remain a chronic source of sediment. E10- Road Decommissioning Implementation- BMPs were properly implemented 23 of 24 decommissioned roads. Effectiveness- All sites were effectively protected from elevated risks to water quality. Recommendations: During road decommissioning projects, continue to implement BMPs as prescribed. HFQLG Best Management Practices Monitoring: Results 2007 5 F25- Prescribed Fire Implementation- 4 of 34 sites did not have proper implementation of BMPs. Burn plans were not available for 2 of these sites. The other 2 sites burned hotter than prescribed. Effectiveness- Of the 34 sites evaluated, only one had ineffective application of BMPs. Recommendations: Include measures to reduce risk to water quality and soil resources in all burn plans. Conduct prescribed fires within appropriate burn windows and suspend operations when conditions are not favorable to meet stated objectives. HFQLG Best Management Practices Monitoring: Results 2007 6 Key Findings As indicated by this year’s monitoring results, Best Management Practices (BMPs) continue to be an effective method for preventing impacts to water quality. The prescription, application, and monitoring of these practices should be continued across the HFQLG Pilot Project area. Table 4 summarizes results from the BMPEP evaluations, based on the composite scores for implementation and effectiveness. Results are reported in four categories: IE (BMPs implemented and on-site objectives met), NIE (BMPs not implemented, but on site-objectives met), INE (BMPs implemented but not effective in meeting on-site objectives) and NINE (BMPs not implemented and objectives not met). Note: BMP evaluations employ direct observations of on-site factors that pose risks to water quality.
