The person who put the Land into easement sold basically all rights with the easement to usda. Know that going in.
You basically retain the rights to pay taxes, hunt and fish. All other rights belong to usda. That includes rights to cut trails, food plots, harvest nuts, berries, timber,etc.
You can ask for a compatible use authorization for trails, food plots, manage water levels, etc. It is not a right but typically granted. Ask for a copy of existing compatible use and copy of the warranty easement deed restrictions before you go too far.
It's typically a good deal for hunting and fishing. But not much more.
