a Camera trap grid area is defined by a 100% Minimum Convex Polygon around all camera stations.
b We followed two survey protocols, Split-grid: where the entire grid was sequentially surveyed in two halves, and Sim.: Simultaneous, where all camera stations were deployed in a single phase.
c Number of photographic captures of different individuals or images obtained more than 1 hour apart.
d The number of independent adult photographic captures per 100 trap days.
e Values within parentheses represent the number of independent photographic captures that did not permit identification to individual.
f SECR density estimation was possible at these sites.
