The Nature Conservancy The Mission of the Nature Conservancy is to conserve the plants, animals and natural communities that represent the diversity of life on Earth by protecting the lands and waters they need to survive global organization 50-year history of conservation results science-based partner-oriented consistent, proven framework for mission success

Why measure ecological integrity? For Biodiversity Parks: Ultimate conservation goal: Improve/maintain biodiversity and requisite ecological features Comprehensively assess threats to targets Set quantifiable, credible objectives for conservation projects Develop and prioritize monitoring plans Identify and prioritize research needs Inspire and galvanize stakeholders re the changing status of the natural world Target Viability Assessment

A history of measures in TNC 1950-80’s: $$ and has (“bucks and acres”) 1990’s: Biodiversity Health & Threat Abatement (limited implementation) 2000: Integrity Team advances new “ecological integrity/viability framework” 2002: Conservation Measures Partnership 2003: TNC Conservation Measures Group born. Organizational objectives for implementation everywere TNC works.
10
Assessing Ecological Integrity: 3 Categories 1. Size Abundance and/or demographics of the population/community 2. Condition Composition, structure, & biotic interactions 3. Landscape Context Landscape-scale ecological processes, adjacency and connectivity Rated as Very Good, Good, Fair, or Poor What did we do before?
11
No clear and consistent definition of ratings Little science rigor Documentation optional and sparse Excel-based “5-S Workbook”

An answer: TNC’s framework and tools for improved integrity assessment

The answer: framework and tools for improved integrity assessment Identify Key Ecological Attributes for Focal Biodiversity Identify Indicator(s) for Key Attributes Rate Indicator Status Integrate Indicator Ratings to Determine Status of: Key Ecological Attributes Specific Elements of Biodiversity Integrity of Entire Protected Area of Landscape

Select a limited number of elements of biodiversity that Will be the focus of Conservation Planning and Action Will represent all biodiversity at the site (including marine, aquatic, and terrestrial, biodiversity) 5. Integrate Ratings to Determine Integrity 4. Rate Indicator Status 3. Identify Indicator(s) 1. Identify Focal Biodiversity 2. Identify Key Attributes

2. Identify Key Attributes 4. Rate Indicator Status 5. Integrate Ratings to Determine Integrity 3. Identify Indicator(s) Factors of target ecology that define or characterize the target, limit its distribution, or determine its variation over space and time Attributes of: biological composition spatial structure biotic interactions environmental regimes (both abiotic and biotic processes) environmental and ecological connectivity Size, Condition, and Landscape Context Key Ecological Attributes 1. Identify Focal Biodiversity
19
Measurable entities used to assess status and trends of Key Ecological Attribute(s). Should be: biologically relevant (reflect target health) socially relevant (recognized by stakeholders) sensitive to anthropogenic stress (reflect threats) anticipatory (early warning) relatively easy to measure cost-effective (max. information/unit effort) Indicators 2. Identify Key Attributes 4. Rate Indicator Status 5. Integrate Ratings to Determine Integrity 3. Identify Indicator(s) 1. Identify Focal Biodiversity
20
Virtually all key attributes vary naturally over time. Rate Status of Key Attributes (using indicators) If variations result from non-human factors: can be said to be “natural,”or at least “acceptable.” All conservation action is aimed at managing biodiversity’s key attributes within their acceptable range of variation. We can not consider biodiversity “conserved” unless all its key attributes are maintained within these acceptable ranges of variation. 2. Identify Key Attributes 4. Rate Indicator Status 5.

Poor: Restoration increasingly difficult; May result in extirpation Fair: Outside acceptable range of variation; Requires human intervention Good: Indicator w/in acceptable range of variation; Some intervention required for maintenance Very Good: Ecologically desirable status; Requires little intervention for maintenance 2. Identify Key Attributes 4. Rate Indicator Status 5. Integrate Ratings to Determine Integrity 3. Identify Indicator(s) 1. Identify Focal Biodiversity
23
When data are lacking… Compare to reference systems or places Use experts Treat as iterative, treat as hypothesis Develop criteria for at least on key attribute Focus on “Fair” & “Good” – conserved, or not. Use gaps to drive research priorities
24
Rating Biodiversity Integrity Fair One or more key attributes are rated Fair (outside its acceptable range of variation)Fair Poor One or more key attributes are rated Poor (difficult to restore)Poor Good Good Majority of key attributes are rated Good (within their acceptable ranges of variation) Very Good Very Good Majority of key attributes are rated Very Good Biodiversity Elements’ Ecological Integrity is Rated If: 2.

Summary Ecological Integrity Measures are essential for determining ultimate outcomes in biodiversity parks Tool are available from TNC for scientifically credible and consistent measurement Measure Key Ecological Attributes & their status relative to natural/acceptable ranges of variation Biodiversity is conserved when all key attributes are within acceptable ranges Use ecological integrity results to drive investments in action, monitoring, stakeholder awareness and research
