Future Distribution of Birds in non-native vegetation, RCP 45

The distributions of 73 bird species were modeled and mapped for the Georgia Basin region within the NPLCC planning area, following Schuster & Arcese (2013). Species maps were developed using a suite of landscape covariates known to influence bird species occurrence (e.g., road density, stand age, tree species presence, proximity to other land uses; Schuster & Arcese 2013), and the results of these ‘occupancy models’ were used to predict species occurrence across the entire study region for 73 bird species using over 90,000 observations of species presence/absence provided from ebird (Sullivan et al. 2009).
