Evaluation of wildlife-habitat relationships data base for predicting bird community composition in central California chaparral and blue oak woodlands

The California Wildlife-Habitat Relationships (WHR) database can be used to assist resource managers to evaluate effects of habitat manipulations on wildlife. The accuracy of predictions from WHR was evaluated using data from bird surveys conducted during winter and spring 1984 and 1985 in chamise (Adenostema fasciculata) chaparral, mixed chaparral and blue oak (Quercus douglasii) woodland. Considerable variability between habitat types was found for errors both of commission and of omission.
