An objective of many camera trapping studies is to understand factors that influence the probability a species will occur at a location in space. Interspecific interactions can strongly influence how animals use space, and camera traps allow us to record detection / non-detection of many species within ecological communities. Recent advancements in occupancy modeling techniques have allowed scientists to simultaneously evaluate how both environmental factors and interspecific interactions influence the probability a suite of species will occur at a location in space. This workshop session will introduce users to recently developed multi-species occupancy models. We will first discuss basic sample design issues and identify how to properly format data for analyses. We will then outline a modeling strategy that proceeds by fitting sequentially more complex models of species interactions. Throughout, we will illustrate how to fit multi-species occupancy models within the R environment and will share code used to conduct example analyses with workshop participants.
