I am currently majoring in Conservation and Wildlife management. just like everyone said stay in school and do lots of vol. work. I spent the entire summer working on a Whitetail ranch in Texas. it was truly a great experience and i wouldn't have been able to do that without what i had learned in school thus far. My plans for after school are, to either become a game warden, wildlife biologist, or possibly a whitetail biologist on a white farm like where i worked over the summer. the only other thing i can tell you that will be helpful is to check out the texas A&M job board, there are always new jobs being posted everyday and it will give you a feel for what is out there. here is the link
