Presentation Outline Strategic habitat conservation? Project Goals
– Vision for the final products– Process – structured decision making
Decision support tool roadmap– Defining and dividing the problem– Priority birds
Objectives – bird habitat conservation Alternatives – selecting focal (surrogate) species Consequences of the selection
– Landscape characteristics Objectives Mapping priorities
Strategic Habitat Conservation? Biological planning
– Ecological context (Threats and limiting factors)– Selecting surrogate bird species (SDM)– Population objectives – SAMBI Plan– Species-habitat relationships – Jaime, Steve, Matt
Conservation Design– Habitat required to meet the population objectives - ???– Desired landscape configuration (SDM) – Decision support tool
Where will we get the best response from conservation?

LMV JV decision support tool One focal habitat –
bottomland hardwood forests
Landscape dominated by agriculture
Goal: target populations of surrogate forest bird species
Primary means – Reforestation
5
6
EGCP JV open pine decision tool One focal habitat Complex landscape Goal: target populations of
surrogate open pine bird species
Primary means:– Longleaf restoration– Improved management of
existing habitat– Habitat acquisition
Similar projects

Vision for the final product(s) Multiple habitats Complex, dynamic landscape
– Urban growth– Climate change
Goal: target populations of many surrogate bird species
Product(s)– Map of highest priority areas for each habitat type

How do we get there? Structured Decision Making
– Process for making smart choices References

Introduction to SDM Important decisions are made in any action or policy Smart decisions are fundamental to success Tools available to professionals:
– Economics– Psychology– Statistics– Biology and ecology– Project management
Ignore basic principles of sound decision making– Not just an “art”
10
Five core elements - PrOACTProblem – Solve the right problemObjectives – Describe the desired outcomesAlternatives – Consider any reasonable actions that
achieve the outcomesConsequences – Describe how well alternatives
meet objectivesTradeoffs – Evaluate consequences of each
alternative
– Core of structured decision making (Hammond et al., 1999).

Three additional elements - URL
Uncertainty – Understand the limits of the data and models
Risk Tolerance– Low tolerance ~ grave consequences– High tolerance ~ less serious consequences
Linked Decisions– Do choices made today influence choices to make
tomorrow?
More advanced concepts

Reasons for SDM process
Group psychology encourages conformity– Results in erroneous choices– Fail to address individuals’ priorities
Don’t explore minority views
Real decisions left to someone else– Managers provide “competent options”– Dealing with complexity -> administrators– Neglects importance of individual decision making– Overlooks diversity of approaches/perspectives
