Broad Terrestrial Ecosystem Inventory (BEI) habitat mapping (at 1:250,000) was used to define habitats to be evaluated and Provincial Wildlife Habitat Ratings Standards used to assess the habitat of 26 bird species that when in British Columbia depend on the dry forests and grasslands of the interior of the province for part of their habitat requirements. This study area of this project was the entire province of BC.(Province Wide)

This project was completed in accordance with the Provincial Wildlife Habitat Ratings Standards Resources Inventory Committee 1999) and was based on the Broad Ecosystem Inventory units (Resources Inventory Committee 2000). The project files include project reports and species accounts. The study area covers the entire province of BC. Habitat potential was evaluated and rated for a number of provincially important bird species that rely on steppe, shrub/steppe, dry forests and surrounding habitats for breeding, rearing of young, feeding, or wintering. Twenty-five species were chosen including ten that live in dry forested habitats and 15 that live in mainly open dry grassland and sagebrush steppe habitats, although many species will use both forested and grassland habitats in order to satisfy part of their life requisites. Wildlife Habitat Ratings (WHR) were developed for the following species: B-BAGO - Barrows Goldeneye, B-FLOW - Flammulated Owl, B-SOW - Western Screech-Owl, B-LEOW - Long-eared Owl, B-LEWO - Lewis Woodpecker, B-WISA -Williamsons Sapsucker, B-GRFL - Gray Flycatcher, B-PYNU - Pygmy Nuthatch, B-NAWA - Nashville Warbler, B-CAFI - Cassins Finch, B-STGR_PR - Prairie Sharp-tailed Grouse B-LBCU - Long-billed Curlew, B-SWHA - Swainsons Hawk, B-RLHA - Rough-legged Hawk, B-STGR_CO - Columbian Sharp-tailed Grouse, B-SEOW - Short-eared Owl, B-COPO - Common Poorwill, B-WEBL - Western Bluebird, B-MOBL - Mountain Bluebird, B-SATH - Sage Thrasher, B-BRSP - Brewers Sparrow, B-TISP - Timberline Sparrow; B-LASP - Lark Sparrow; B-GRSP - Grasshopper Sparrow, B-BOBO - Bobolink,and B-WEME - Western Meadowlark.This project was funded by the Habitat Conservation Trust Fund (project 0-251). Tony Button of the Terrestrial Information Branch, Ministry of Sustainable Resource Management was project manager and also provided data management and map production support. Lynne Bonner of the Terrestrial Information Branch, Ministry of Sustainable Resource Management correlated the habitat ratings to comply with the Resources Inventory Committees 1999 British Columbia Wildlife Habitat Ratings Standards.
