Data Do Ranger Stations Deter Poaching Activity in National Parks...

Interesting practical question. The attached analyses that impact and the findings allow an evidence-based optimization of ranger station siting. Another of our Kenyan elephant papers touches upon the impact of patrol routes on elephant distribution.

Thanks Ali! This is one of the only papers that discusses this issue in the literature. I am familiar with it, but still much more needs to be done on this issue.

Thanks Hein for the paper. But do you know of any studies with recommendations on such optimizations? 

Ali, this may be anecdotal to your question, but see the attached article, where Binkley and his colleagues found the Quaking Aspen Ranger Station on the Kaibab Plateau provided refuge to aspens in the 1920s, when they would have been browsed on by mule deer.  Very interesting to think about.  Best, Jeff

Thanks a lot Jeff! Really interesting results.  

Thanks for sharing this paper! This is actually the paper we published related to the question I made here. I wanted to make sure I'm not missing any literature.
