Summary

Values for predicted probabilities of avian species occupancy were determined using colonization-extinction models (MacKenzie and others, 2003) as implemented in R (Version 3.4.4; https://www.r-project.org/) via the ‘colext’ function of the Unmarked package (Version 0.12-0; Fiske and Chandler 2011). Performance of a null model (without covariates) and 153 additional models that assessed the effects of geographic coordinates and habitat context covariates were evaluated using Akaike information criteria (AIC; Burnham and Anderson, 2002). When more than one model had substantial support, their respective model weights were used to spatially predict occupancy relative to covariate influence. Predictive model covariates and weights are [...]

Purpose

Species occupancies, area of sustainable forest habitat, and area of occupied habitat were predicted to aid in assessing the area of sustainable forest habitat supporting the Lower Mississippi Valley joint Venture's population objectives of silvicolous birds within the Mississippi Alluvial Valley Bird Conservation Region.
