# Vertebrate-habitat relationships: Logistic regression models predict probability of occurrence of bird and small mammal species in western Oregon, 1998-1999 ## Dataset - **Database Code:** WE027 - **Title:** Vertebrate-habitat relationships: Logistic regression models predict probability of occurrence of bird and small mammal species in western Oregon, 1998-1999 - **Abstract:** Logistic regression models predicting probability of occurrence of bird and of small-mammal species were produced using animal-habitat data sets from throughout western Oregon (Garman and Cole 1999 - Vertebrate Habitat Relationships Data Bank (VHRDB), Report to Coastal Landscape Analysis and Modeling Study). Regression coefficients, variables, and metrics related to model predictions are provided here under Entity 1, and in VHRDB as VERTLOGR. - **Keywords:** habitats; populations; trophic structure; modeling; animals; birds; small mammals; Long-Term Ecological Research (LTER); populations - **Temporal coverage:** 1998-01-01 to 1999-01-01 - **Principal Investigator:** Steven L.
