Habitat Modeling for Badgers, Fishers, and Black Bears: From Research to Application

This document outlines the methodologies employed in habitat modeling for American black bears, fishers, and North American badgers. It discusses the development of predictive models using radiotelemetry data on a 1:20,000 scale, aimed at various forest landscapes. It incorporates conservation assessments, population viability analyses (PVA), and the identification of risks associated with different management scenarios. The analysis and applications for each species are reviewed, highlighting the present status of research and future directions for effective habitat management.

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
