PUBLICATIONS AND PRESENTATIONS

Biologists at The Wildlife Project collect and interpret data in as scientifically rigorous a fashion as possible. This not only values the data and justifies the handling of wildlife species, it creates results that are often peer reviewed (outside of our company) for publication, and are open to scrutiny by all.  We feel that our work quality must reflect a level of scientific rigor to support the sharing of data whenever possible.  

We also frequently present new information on wildlife natural history and technique development to conferences and groups of scientists whenever we can.  We believe that sharing "discoveries" promotes best practices in management and protection of wildlife species and populations.
