A short history … LMV JV - Bottomland hardwood restoration Objectives: birds, single habitat, simple landscape EGCP JV - Longleaf Pine Restoration Objectives: birds, single habitat, complex landscape AC JV - Designing Sustainable Landscapes Objectives: birds Multiple habitats, dynamic landscape Dynamic landscapes – climate change, urbanization Optimal Conservation Strategies Multiple objectives: cultural and natural resources Multiple habitats (systems) Dynamic environments – climate change, urbanization

Project Scope and Spatial Extent Spatial Extent: South Atlantic LCC Scope: Conservation-related decisions by partners in SA LCC
6
Relationship to SA LCC The purpose of this project is to develop a framework to help guide strategic decisions for conservation delivery across the South Atlantic Landscape Conservation Cooperative (SA LCC). Strategic decisions as those that maximize the LCC partners’ ability to meet large-scale, long-term objectives for complex systems. Strategies are targeted collections of actions by SA LCC partners to implement conservation.
7
Objectives Based on input from LCC: 1. Identify focal species 2. Assess the state of focal species 3. Determine population and habitat objectives 4. Develop habitat relationship models 5. Predict the effects of conservation on focal species
8
Objectives 6. Determine optimal conservation strategies Where conservation is needed What actions should work best When action should be taken 7. Identify key elements for monitoring Learn more about direction and effects of climate Measure progress towards objectives
9
Structured Decision Making Pr oblem – Solve the right problem O bjectives – Describe the desired outcomes A lternatives – Any reasonable approach to meet objectives C onsequences – Predict how well alternatives meet objectives T radeoffs – Incorporate values, optimal solutions U ncertainty – implementation, response, system… R isk – Gravity of the decision L inked decisions – Interactive effects in space & time
10
Why should we do this? Complicated problems… Ends and means can become confused Ends determine how we measure success Think about conserving habitat… Do we measure success in terms of acres or populations? Means set the stage for strategies Which strategies to best achieve means to meet our ends Requires predictions of consequences Rewards, uncertainty, and risk influence decision
11
My naïve conceptual model …is this really the problem?

15
What are the decisions? List decision makers for ALL conservation partners Decisions they make Types of actions Grouped decision makers by decision type 1. Resource managers 2. Resource regulators 3. Project funders 4. Advocates Not mutually exclusive: EPA – manages, regulates, and funds conservation projects TNC – manages and advocates
16
Objectives network Includes fundamental and means objectives Objectives: object of value (e.g. populations, human health) preference for the direction of change (e.g. maximize, minimize). Fundamental objectives - ends in themselves. E.g., Maximizing human health Means objectives - things that we want to achieve in order to meet our fundamental objectives. E.g., Maximizing water quality helps us meet our fundamental objectives of maximizing human and wildlife health Linkages among objectives – causal relationships

19
Problem statement The LCC should serve as the umbrella group under which all of the partners come together to make decisions regarding the conservation of natural and cultural resources. With that in mind, our problem has two parts: 1) Help partners choose strategies that are based on a shared scientific understanding about the landscape of the Southeast. 2) Help partners solve shared problems with similar objectives.
20
What do LCC partners want to know? 1. Where they should take action to contribute most to LCC objectives. 2. How will those actions contribute to their agencies’ objectives.
21
Next steps Means objectives – prediction of consequences Need to be more explicit about desired conditions and expected results (relationships) Identifying data needs and potential sources Where will we get the data and models? SERAP LCC Partners Develop decisions or strategies explicitly
22
How do we predict consequences? SERAP data & models Downscaled climate projections Sea level rise (part) Land cover change Responses of birds But for many objectives… LCC partners – EPA, NPS, SARP, PARC, ACJV, USFS, USGS Facilitated by SA LCC Science Coordinator In-house Expert opinion LCC funded research Surrogates
23
Developing strategies Action – something done to benefit conservation e.g., plant longleaf on agricultural lands Portfolios – collections of actions e.g., restore all-aged forest by eliminating pasture grasses, plant longleaf, thin, burn, and select cut e.g., achieve hardwood DFCs on forested lands
24
Developing strategies Strategies – portfolios optimally implemented in time and space to maximize their value to the LCC. 1. Achieve DHCs (all habitats?) in areas that will enlarge existing reserve networks on public lands to mitigate for anticipated changes in sea level rise and precipitation patterns on fish and wildlife habitat. 2. Achieve DFCs in areas that will enhance corridors between existing habitat patches based on current climatic conditions 3. Optimal – maximum value. Decision – choose strategy that maximizes utility
25
Tradeoffs Value – Degree to which fundamental objectives are achieved Rewards – Number of cultural sites protected Value – Proportion of all cultures represented Tradeoffs – Incorporated as relative value (weights) of performance on each objective How much are you will to compromise? Utility – Total value of the strategy Discounted by uncertainty and risk Values and weights determined by partners
26
What did we need? Small working group Refine objectives Structure decision (prioritization) models Identify data needs & priorities Iteratively review and refine tools Establish tradeoffs LCC Leadership identifies membership Decision makers Resource experts Land managers SERAP PIs
27
How did we approach this? LCC established a small working group (8-10) 2 webinars to establish context & frame problem 1 multi-day workshop (3-day session) Prototype model – decision network Identify needs & resources Follow up workshops (3 1-day sessions) Develop strategies Refine & develop means objectives Review assumptions & results Steering committee Reviews objective values Establishes & agrees on tradeoffs Decision to implement
28
Time line DateNext Steps By end of May Identification of technical needs/resources Engagement of SERAP partners By early June Inclusion of additional working group webinars June 16 Update to LCC steering committee June – July Data development/modeling/analysis August 6 Presentation at ESA August/September Presentation/engagement of technical staff for decision makers December Final report on prototype. Identification of next steps for model refinement.
