I'm enrolled in WHIP (wildlife habitat improvement program), through the NRCS. They bought me some native warm season grasses. Also, I'm in Partners for Fish & Wildlife. They dug 8 duck ponds for me, put in a water control structure, and gave me 50 lbs of switchgrass and wildflower seed to plant around the ponds. The only stipulation is I can't fill them in for ten years.
NWTF gave me a bag of corn this Spring. You have to promise to leave it standing for the wildlife , plus sign a form saying you won't sell it.
