With the prolific growth in the use of digital wildlife cameras over the past 15 years, the number of papers on camera trapping have similarly ballooned. We have listed below some key papers pertinent to designing a camera trap study. We are currently working on making this repository interactive, with the hope that our members will be able to add to this repository in the future.
Camera Trap Papers Directory
WildCAM's annotated bibliography: This is a literature synthesis of camera trap methodology papers published in the last ten years. Encompassing literature on study design and data processing, it can be used as a review to give researchers and practitioners insight into what the peer-reviewed literature suggests regarding best practices.
A selection of camera trap papers is listed below (this is not meant to be an exhaustive list).
