- This research was conducted in two pine savannas (Joseph W. Jones Ecological Research Center and Silver Lake Wildlife Management Area) located in southwestern Georgia, USA, 2011–2013

aInformation-theoretic approach was used to evaluate each larger landscape variable at multiple spatial scales (i.e., 40-, 80-, 120-, 160-, and 200-m radii). The spatial scale for each landscape variable was selected using Akaike’s information criterion (AIC) adjusted for small sample size (AICc). In cases where multiple models for a landscape variable had AICc scores <2.0 units from each other, we selected the scale that corresponded closely to Conley et al.’s (2015) maximum value (≤3 ha) suggested for future turkey nest site selection studies resulting in the selection of the 80-m scale
