R-code, Dataset, Analysis and output (2012-2020): Occupancy and Probability of Detection for Bachman's Sparrow (Aimophila aestivalis), Northern Bobwhite (Collinus virginianus), and Brown-headed Nuthatch (Sitta pusilla) to Habitat Management Practices on Carolina Sandhills NWR
Description
This reference contains the R-code for the analysis and summary of detections of Bachman's sparrow, bobwhite quail and brown-headed nuthatch through 2020. Specifically generates probability of detection and occupancy of the species based on call counts and elicited calls with playback. The code loads raw point count (CSV files) and fire history data (CSV) and cleans/transforms into a tidy format for occupancy analysis. It then creates the necessary data structure for occupancy analysis, performs the analysis for the three focal species, and provides functionality for generating tables and figures summarizing the key findings of the occupancy analysis. The raw data, point count locations and other spatial data (ShapeFiles) are contained in the dataset.
