There's plenty of research out there. The PGC website is full of information. Do a QDMA search for information from them. Other states have a wealth of information as well. I'd do your own figuring and interpreting of the research though. Being a hunter yourself you can make your own calculations and determinations of the data. Just realize when talking to folks on either side of the arguement you'll get facts supporting there side or bits and pieces of information that don't paint nearly as complete or accurrate a picture as you'll need . So you will need to do your own leg work. Good luck, the topic is certainly current and relevant. Juniorpc.
