I have 173 acres and all but maybe 10 is wildlife friendly, not devoted to wildlife, but every effort is taken to make it work for both wild and farm life at the same time. Most of it costs me nothing, I just adapt whatever I'm doing as I work thru my goals for the homestead.
1. no open areas more than 200' from good cover
2. my pastures feed horses, deer, quail, sandhill cranes, turkey, grey and fox squirrel, and other wild critters as well as cattle starting next spring. My farm had 90 acres of solid pine plantation, and now those 90 acres are silvapasture, so they can feed and shade cattle and horses, produce timber income, and support wildlife at the same time.
3. Any mast producing trees and bushes are left in the pastures. I have about 100 native persimmon I'm trying to encourage.
4. Except for that 10 acres, no more than 50% of the pastures are mowed each year so that the native plant seeds are produced for wildlife feed
5. In a 40 acre portion of the farm that is almost all wild, I plant a deer mix in the openings that were created when I logged the pines. It is the same seed I plant in pastures but in different proportions: brassicas, rape, turnips, rye, milo, cowpeas, millet, and a few other odds and ends. I'm still experimenting with what does best.
6. I've planted 50 trees for the critters that are mast producing, chestnuts, apples, and persimmons mostly. This has been my biggest expense, but the trees are planted where they will serve as pasture divisions and windbreaks, so I get a bit of value out of that. And I'll get my share of apples hopefully.
7. A project for the coming year includes two ponds to provide wildlife water. Both ponds are being dug to provide fill for construction projects. One pond will be well fed and irrigate the orchard/gardens. The other pond will get all the water from my roof and grey water from the house. It will also serve as a fire break, which is critical in my area.
8. Other projects on the list are bat and bird houses. I'll do that with scrap lumber from the home building.
Why? Because it is good for the world. I'm a tree hugger at heart and I think it is everyone's responsibility to leave their piece of the world a little bit better than they found it. And it makes me happy to see the 2 momma bears and the 5 cubs between them. And deer, turkey, wild hog, and quail taste good.
