To obtain experience, you can volunteer or work as a wildlife biologist for a state or federal agency such as the U.S. Fish and Wildlife Service or National Park Service. Another way to meet the experience requirement is to complete either a master's or Ph.D. degree program in wildlife biology or a related subject. A master's degree counts for one year of experience, a Ph.D. counts for two years, and a person who holds both degrees is granted the equivalent of three years of experience.
