Presentation Transcript

  1. Habitat modeling for badgers, fishers, and black bears: from research to application Richard Weir Artemis Wildlife Consultants

  2. Outline • Research • Predictive models • PVA • Useful products?

  3. Research studies • American black bears: • Nimpkish Valley • Helen Davis, Tony Hamilton, John Deal • Fishers: • Williston region • Rich Weir, Fraser Corbould • North American badgers: • East Kootenay, Thompson • Nancy Newhouse, Rich Weir

  4. Modeling objectives American black bears • Develop a predictive model from radiotelemetry data • 1:20,000 scale application in coastal forest landscapes

  5. Modeling objectives Fishers • Develop a multi-scale predictive model from radiotelemetry data • 1:20,000 scale application in SBS landscapes

  6. Modeling objectives North American badgers • Conduct conservation assessment • Integrate: • Habitat modeling • Derived from research studies • Population viability analysis • Identify risks associated with various scenarios

  7. Extending research to application • Based on information-theoretic analyses of candidate set of models • Using “probability of use” to estimate habitat quality • Various spatial and temporal applications • Forecasting supply • Determining effects of varying management scenarios • Predicting population effects (?)

  8. Where are we now? American black bears • Analysis complete • Predictive model identified for females • Undergoing peer-review for publication Awaiting application and verification

  9. Where are we now? Fishers • Habitat analysis beginning • Need to develop scale-based approach Awaiting application and verification

  10. Habitat capability for fishers • Completed in 2003 • Expert-based • Based on: • Biogeoclimatic • Ecosection • Harvest information • Currently used as base for population estimate

  11. Where are we now? North American badgers • Habitat analysis completed (both studies) • Habitat models developed for EK and Thompson Determining inputs for PVA

  12. Incorporating selection processes that occur at multiple spatial scales Assessing effects of non-habitat variables Applying and testing HSMs The road ahead
