The first thing you need to do to go to a good college is have at least a GPA of 2.5 or over. Also you need to take classes in college like tree biology and wood anatomy. And you need to have a basic knowledge about trees and wild life so you can have the basic idea about your job.
There are a lot of job openings so there is a good chance that you will get hired straight out of college. You get to see great scenery. Also you can get great retirement and good government benefits.
