Abstract or Summary
  • This report and especially the accompanying Detail Files and MapFiles provide relatively detailed information on status, trends, distribution, limiting factors, and conservation needs of all of the Willamette’s wildlife species, listed plants, and vulnerable habitats. Data on habitat suitability for each species is provided by watershed (170 HUC6s), elevation (6 zones), and land ownership (2 categories). Tables and maps describing the possible extent of historical and current habitat are presented for 43 focal species. Databases also are provided for helping assess the tradeoffs among species that accompany every restoration or land management decision. Analyses conducted for this project demonstrated that well-managed public lands, when augmented by the 93 Priority Conservation Areas identified by TNC’s Ecoregional Analysis, would collectively offer some level of protection to all of the subbasin’s species. The combination of public lands and Priority Conservation Areas would provide some amount of habitat to all wildlife species in 53% of the 170 individual watersheds. The analyses also showed that focal species described in this report may represent the subbasin’s rarest habitats better than species that have been used previously as HEP (Habitat Evaluation Procedure) indicators for assessing mitigation credits.
