Connecting science and management • What is the problem or decision? • What is the objective to be addressed related to the problem? • How can we measure whether we have met the objective?

Doing science in the face of “Wicked Problems” • Scientific complexity and uncertainty • Challenging to understand vulnerability and adaptive capacity of complex interacting systems operating at many scales • Is better science the issue? Decision-making context is such that better technical information alone does not necessarily lead to better decisions • Many stakeholders (emotional?); many interests; differing perceptions and tolerances of risk …the problem isn’t solely getting better technical information • Improving science and technical knowledge no guarantee that the science will be used; SECSC wants to avoid developing great answers to questions that aren’t being asked • Urgency – management actions won’t be postponed until scientific uncertainties and values trade-offs are resolved
SECAS as an example of Wicked Problems …to develop and pursue a common vision of habitat conservation that can sustain fish, wildlife, and other natural and cultural resources across ecosystems in a way that meets expectations of the public, the Administration, and the Congress. (Ed Carter) • Is better science all we are lacking to implement SECAS? • What resources are most important? For whom? • Who are the key stakeholders? What are their priority interests/decisions? What are good indicators/endpoints to measure if an objective is achieved? • Do we know how to predict these endpoints? • WHERE TO START?
Responses to the SECAS challenges • From perspective of a “scientific study” culture • Most of us trained in a ‘study culture’: a technically-oriented problem is identified and a study is launched. • How the study information will contribute to better choices among mgt. options not always specified. • From the perspective of a “decision” culture • Reality of environmental management: Once a problem emerges, decisions will be made, even though the science is uncertain, stakeholders are emotional and values are entrenched. • This perspective reframes wicked problems in terms of needing to makechoices, not doing scientific studies.
SDM as a context for framing and making environmental management choices • SDM: organized, inclusive, and transparent approach to understand complex problems in a decision context and generate and evaluate creative alternatives. • Assumption: good decisions account for values (what’s important) and consequences (what’s likely to happen, relative to what’s important, if an alternative is implemented?) “A formal application of common sense for situations too complex for the informal use of common sense.” (R. Keeney)

SDM example: Objectives and Endpoints/Performance measures • Overall or Fundamental Objectives • The thing(s) we care about • For example, maintain healthy populations of native vertebrates and invertebrates in understory of Ponderosa Pine forest • Endpoints/performance measures • Specific metric for consistently estimating and reporting consequences of mgt. actions for an objective • Indicates how an objective is to be interpreted and understood for this decision.
SDM example: Management actions • Developed with the objective(s) in mind • Generation of alternatives may be iterative and result in hybrids that combine ideas • Alternative actions in this example • Prescribed understory fire • Mechanical thinning of understory • Timing • How frequently? • Under what conditions?
SDM example: Using models to assess consequences • These models might be mental, conceptual, or quantitative • Should explicitly link management actions to endpoints associated with objectives • In this example, use of models to predict • How basal area, vegetation composition , native animal communities (possible endpoints) change as a function of time, treatment, and habitat conditions
SDM example: Optimal Solution • Found by integrating • Objectives • Actions • Models • Identify the action and its timing that best achieve the objectives • An optimal solution might call for, say, thinning whenever the basal area exceeds 85 ft2/ac
Key Elements in Structured Approach • Combine values-focus and analytical judgment • The objectives (values) are discussed first, and drive the rest of the effort, including conceptual models and analysis • Break the problem into components, separating objectives and policy option definition and scientific assessment • Use this management context to focus scientific assessment • Recompose the parts to make a decision • This is in contrast to intuitive decision-making • which tends to frame a problem in terms of familiar and relatively accessible constructs and methods (e.g., GIS-based suitability analysis using maps/coverages that already exist)
Decision culture: PrOACT approach • Defining the Problem • Objectives • Actions • Consequences (conceptual and quantitative models) • Trade-offs and optimization
Defining the SECAS Problem …to develop and pursue a common vision of habitat conservationthat can sustain fish, wildlife, and other natural and cultural resources across ecosystems in a way that meets expectations of the public, the Administration, and the Congress. (Ed Carter) • Identify the decision’s essential elements • Who are the decision makers? • Other interested parties, timing • What are the legal and regulatory requirements? • What are the different scales of decisions (SEAFWA wide, individual states, “local” management entities (town, county, refuge)? • BCG example: protect urban WQ
SECAS objectives • Objectives concisely define ‘what matters’ about a decision. • An explicit statement of one or more objectives allows focused discussion, identification, and evaluation of management options • Objectives must be carefully defined and accepted by key stakeholders as the basis for making the decision(s) • The objectives driveeverything else • Focus on understanding objectives first, before discussing management alternatives and assessing consequences • BCG example: Meet WQ standards.
SECAS Performance measures/endpoints • Specific metrics for assessing and reporting how well a management alternative performs with respect to an alternative. • To be useful as a performance measure or endpoint we need to ask • Does this endpoint measure something that indicates if the objective has been achieved? • Is this endpoint something that be assessed using objective approaches (e.g., models)? • BCG example: BCG tier membership probability
Objectives and performance measures associated with reservoir operating decisions
SECAS potential management actions • Identification of mgt alternatives driven by the question “how can the objectives be achieved?” • Use the objectives to generate alternative management action strategies • Generation of alternative strategies can take several “rounds” as elements of initial ideas are combined and recombined to create hybrid alternative actions • Don’t get fixated on the initial set of options • Develop creative & unique alternatives before assessing feasibility and efficacy
SECAS: Assessing consequences • Consequences tables can be used to identify the science and conceptual models needed to assess now mgt actions affect the desired future. • “…decision making is a forward-looking process….And if decision making is the attempt to achieve a desired future, then any such attempt must include, implicitly or explicitly, a vision of what that future will look like.” • Sarewitz et al. (2000). Prediction: Science, Decision Making, and the Future of Nature. Island Press.
Consequence Tables… …drive the make-up of conceptual models
Conceptual models • Graphically show relations between stressors and responses, used to explore: • Relations between possible actions and endpoints of interest to managers • Competing hypotheses about causal mechanisms • Sources of uncertainty • Possible model specifications
The temptation in identifying some key elements of the SECAS conceptual model (CM)… • Ecological response • Habitat connectivity • Streamflow changes • Loss of sensitive species • Changing wildfire regime • Human settlement • Drivers of landscape condition • Climate change • Land cover change • Energy development • Transportation • Sea level rise • Existing policies …is to define a “standard” science study where the problem is narrowly focused in technical terms
Further elaboration of aSECAS CM • Drivers of landscape condition • Climate change • Land cover change • Energy development • Transportation • Sea level rise • Existing policies • Ecological response • Habitat connectivity • Streamflow changes • Loss of sensitive species • Changing wildfire regime • Human settlement • SECAS objectives/endpoints • Environment: Sustainable fish and wildlife populations • Economy: Flourishing communities • Equity: Fairness among generations
3 tasks before conceptual model development • Define the problem or challenge. • Define the priority SECAS objectives: • Various conservation/natural resource sectors; Production/consumption sectors (agr; urban; energy; transportation; other regulators); the public at large • Key: what scale: (eco)regional, state, local? • Coming up with endpoints that can be used and to measure “success” at addressing these priorities • Using these objectives to define an initial set of possible management actions/scenarios
Responding to the SECAS problem/challenge? …to develop and pursue a common vision of habitat conservation that can sustain fish, wildlife, and other natural and cultural resources across ecosystems in a way that meets expectations of the public, the Administration, and the Congress. (Ed Carter, TN WRA) • Conceptual models should • focus and define the science needed to assess the consequences of possible management activities. • We want to know: will these management activities let us accomplish the key objectives associated with this challenge
