Viability Assessment What is it? Viability 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
7
Viability assessment helps teams answer important questions: Bog frog 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) Viability Assessment Viability Assessment What is it?

The Basics Viability Assessment
12
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
13
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 1) Define “key ecological attributes” of your target. Viability Assessment

Indicators are measurable aspects of the Key Ecological Attribute that inform us of its status or “health” Indicators Indicators are what you measure Key Attribute: Circulatory systemIndicator: Blood pressure Viability Assessment

Tips for Selecting KEAs Pick factors that are critical for long-term viability – characteristics that, if degraded, would seriously jeopardize the target’s ability to persist for 100+ years When in doubt, pick characteristics that are likely to be affected by human activities Look for a few really key ecological attributes… versus many desirable or descriptive characteristics Key ecological attributes are what’s important… Viability Assessment
50
Tips for Selecting Indicators Look for indicators that: Strongly relate to the status of the key ecological attribute Are efficient & affordable to measure Can reasonably define what constitutes “Good” Desirable indicators... Might provide an early warning to serious stresses Might assess two or more key ecological attributes e.g. Presence of young cypress in a floodplain forest as an indicator for both hydrological regime & reproduction of dominant species Viability Assessment
51
Be Prepared to Accept Uncertainty!! 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) Viability Assessment

Incomplete is OK! Indicator Ratings Bold=Current Italics=Desired Focal Target CategoryKey AttributeIndicatorPoorFairGoodVery Good grassland - Type X Size Size/extent of characteristic communities / ecosystems aerial extent in acres > 100,000 acres How important is it to fill out all ratings in this case where Current & Desired status is Very Good? 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 Viability Assessment

Key Ecological Attributes – important characteristics of targets Indicators – what you actually measure “Reduce, reuse, recycle” KEAs if one will work for more than one target Rating is important (especially Good versus Fair) Viability assessment is iterative - if in doubt, just try it... Viability Key Points

Breakout Group Instructions 1.Complete the viability assessment for one of your targets – Identify KEAs – Select indicators – Describe what would constitute “good” status – Determine current and future desired status of the indicator – Complete ratings – Throughout the process, record assumptions and background information Viability Assessment
