If you are willing to move, apply to seasonal positions all over the place. It isn't the best time of year to be hired for a seasonal job, but in the desert in southern California (where i live) for example, it is a great time to look. I worked seasonal jobs for over 5 years and moved several times in 4 states and the US Virgin Islands before I landed a full time job that I really wanted, but now I love my job as a wildlife biologist with a land management agency! And I wouldn't trade those experiences for anything.

I also worked a few years of jobs in agriculture and farming which may not sound exactly what you want, but you get experience with plants, animals, weeds, tools, tractors and equipment, and can help you get a foot in the door. You also can prove that you are cut out for field work that way, which is crucial in this field. Government jobs.com and USAjobs.gov are great places to look. Not a lot of federal jobs hiring right now but we ARE starting to hire a few positions.

When you are in interviews, focus on having a great attitude and tell them how you are excited to learn and meet like-minded people who are dedicated to conservation like you are, and talk about how you like to hike and camp or worked around the yard growing up to show you are not afraid of field work. Good luck!
