Multiple regression models were developed and their predictive power tested for the 5 common secondary cavity-nesting birds in ponderosa pine Pinus ponderosa forests. Variables included 7 vegetation ones and 11 climatic ones. All models were highly significant and explained 50-89% of variation in breeding bird density. Snag density, which appeared as an important variable in 4 of 5 models, had a positive affect on breeding bird density. Snags are the most important variable determining density of most of the secondary cavity nesters.-from AuthorsPonderosa pine inus ponderosa.
