How well do we understand the interactions? • How important is one relative to the others? • Do we understand the underlying drivers? • What are the implications to waterfowl management if one or more linkages weakens or disappears? • Is there a need for structured decision-making to ensure coordination and coherence?
Turning Point Question When you have a choice of whether or not to use information from models to make management decisions, you: • Use models a little • Use models some; mostly other factors • Give equal weight to models and other factors • Use models heavily, along with other factors • Use models almost exclusively
Intuitive (implicit) models often create confusion and controversy • The Adaptive Harvest Management lesson • Biological uncertainties • Agree on process; competing models • The scaup controversy • Why restrict hunting when harvest has nothing to do with the scaup decline? • A need to incorporate habitat variables • We’re going to lose diving duck hunters and destroy waterfowling traditions • A need for hunter objectives
Desired outcomes from structured decision-making • Coherentobjectives • Harvest, habitat, and hunter objectives that all flow together • Coherent models • Integrated models that link habitat changes to demographic changes to continental population status to harvest potential
Desired outcomes from structured decision-making • Coherent monitoring • Monitoring of habitat, population, harvest, and hunter satisfaction in an integrated way • Coherentmanagement actions • Habitat management, harvest regulations, and interactions with hunters, all of which are mutually reinforcing
Implications of structured decision-making • Coherence will require explicit, multiple objectives • Multiple objectives will lead to multiple tradeoffs • Structured decision-making offers: • Transparent goals and assumptions • The opportunity for formal, integrated models • A greater opportunity for learning • Increased management efficiencies
Where to from here? • Explore linkages among harvest, habitat and hunters • Mike Runge – harvest in the context of habitat and hunters • John Eadie – habitat in the context of harvest and hunters • Andy Raedeke – hunters in the context of habitat and harvest • From the established/familiar to the un-established/less familiar; not necessarily in rank order of importance!
Expectations • Think strategically, not tactically • Don’t lose sight of the big picture • Be open-minded and objective • Be inquisitive and creative • Be a participant, not an observer • Keep expectations realistic • May not leave with solutions • Hope to identify a clear path forward • Complex, difficult task
The potential upsides… • “Better” waterfowl population and habitat objectives • Derived from explicit estimates of the quantity of birds desired for harvest, and in consideration of environmental and social objectives • “Simpler” hunting regulations • Potential for a harvest strategy that does not chase populations in response to uncontrollable, short-term environmental conditions • “More effective” management • Coordinated population, habitat, and hunter objectives lead to more efficient use of staff and help stretch shrinking budgets
