Without data, fate of great apes unknown:
At the end of the article, you say that more evidence is needed to determine the best specific law enforcement and conservation factors. I gather that data were lacking for most of the RMAs to break law enforcement strategies down into factors like level of training, salary, numbers of guards, resources and equipment, etc. Is this something that could be analyzed on a subset of RMAs? After all, since great ape populations are declining so fast, we don’t have the luxury to wait 20 more years for answers.
