If you're willing to move all the way across the country, there are some intern positions available with the Department of Natural Resources in Washington. These are great jobs for a forestry student, and there are 4 positions available. I work for the DNR myself, and it's a great agency to work for. Here's a link to the intern positions:

There are also a lot of firefighter positions, which can be more difficult work, but most years you will get lots of overtime and the money adds up fast. These are great opportunites for forestry students as well.

Last but not least there are some Engineering Aide positions, working on land survey crews. These positions pay better than the other ones, I believe.

Good luck. Let me know if you have any questions about the Washington DNR.
