75% of the funding for the Walk-In Area program comes from federal funds generated by an excise tax on the sale of most firearms, ammunition, and archery equipment created by the Federal Aid in Wildlife Restoration Act.  The other 25% is from hunting license sales revenue.  Up until September 30, 2018 GFP also offered signing bonuses to Conservation Reserve Program (CRP) participants to palce their CRP lands in the Walk-In Area program for the life of their CRP contracts.  These signing bonuses were funded by a grant from USDA through Voluntary Public Access and Habitat Incentive Program, a program taht was part of the Farm Bill.
