How to do viability assessment Additional examples of viability assessment Advice for doing viability assessment Viability Assessment What is it? Viability Assessment Viability (ecological integrity) of a conservation target is the measure to which the target is……. resistant to change in its structure and composition in the face of external stresses and resilient – able to recover upon experiencing occasional severe stress Viability Assessment What is it? Viability Assessment Viability assessment helps teams answer important questions: • What key characteristics define a healthy target? • How do we physically measure those characteristics? (indicators) • How is our target doing now? • What do we want to achieve? (ultimate, measurable goals) Bog frog Bog frog This Presentation • • • • Viability Assessment What is viability assessment?

Define key characteristics (“key ecological attributes” or KEAs) of your target. 2. Identify indicator(s) for each KEA 3. Describe what would constitute “good” status 4. Define the current status and desired future status for your target 5. Complete the rating scale for each indicator, using the categories of or . The Details Viability Assessment 1) Define “key ecological attributes” (KEAs) of your target. KEA: Aspects of a target’s biology or ecology that - If present, define a healthy target - If missing or altered, would lead to the loss or extreme degradation of that target over time. Examples: Tropical hardwood forest target: size, connectivity among systems, presence of key species Migratory fish target: population status, access to spawning habitat, quality of spawning habitat The Details Viability Assessment 1) Define “key ecological attributes” of your target. Consider the following categories: Size: •Geographic extent (ecosystem or habitat) •Abundance &/or demographics of the population/community (species) Condition: •Composition, structure, & biotic interactions Landscape Context: •Landscape-scale ecological processes, connectivity The Details Viability Assessment 1) Define “key ecological attributes” of your target.

Viability Assessment • The main purpose of viability assessment is capturing the current state of knowledge • Don’t worry about information gaps • Don’t focus on filling out all indicator ratings! • Viability assessment is an iterative process with successive approximations. You can return during later planning stages to add more detail (if necessary) Be Prepared to Accept Uncertainty!! Viability Assessment 1st Pass Table Target grassland Type X • • • • Category KEA Landscape fire regime Context Indicator fire frequency Grassland target identified Fire regime = Key Attribute (Landscape Context) Fire frequency = Indicator Dense woody cover suggests not enough fire Be Prepared to Accept Uncertainty!! 1st Pass Table Target grassland Type X • • • • • Category Viability Assessment Indicator Ratings KEA Landscape fire regime Context Indicator fire frequency Poor Fair Good Very Good not enough fire Grassland focal target identified Fire regime = Key Attribute (Landscape Context) Fire frequency = Indicator Dense woody cover suggests not enough fire Current status deemed not viable - assigned “Fair” Be Prepared to Accept Uncertainty!! 2nd Pass Table Target Category Viability Assessment Indicator Ratings KEA Indicator Poor Fair grassland Type X Landscape fire regime Context fire frequency not enough fire grassland Type X Landscape fire regime Context fire frequency > 10 years Phone call to local grassland expert indicates natural fire frequency of 5-10 years Good 5-10 years Very Good Be Prepared to Accept Uncertainty!! 3rd Pass Table Target Category Viability Assessment Indicator Ratings KEA Indicator Poor Fair Good grassland Type X Landscape fire regime Context fire frequency not enough fire grassland Type X Landscape fire regime Context fire frequency > 10 years 5-10 years Landscape fire regime Context % grassland w/ 5-10 yr fire return 25-50% 51-75% grassland Type X <25% % area burned at acceptable frequency is key Very Good >75% Viability Assessment Incomplete is OK! Indicator Ratings Bold=Current Italics=Desired Focal Target grassland Type X Category Size Key Attribute Size/extent of characteristic communities / ecosystems Indicator aerial extent in acres How important is it to fill out all ratings in this case where Current & Desired status is Very Good? Poor Fair Good Very Good > 100,000 acres Probably Not Important! - Unless grassland area is threatened by large-scale habitat destruction. - In this case, determining the Fair rating might guide efforts to determine how much to save Where to get more info… Viability Assessment • Examples: TNC Conpro database (TNC) - http://conpro.tnc.org This Presentation • • • • Viability Assessment What is viability assessment?
