If you are going to use a grants program as a financial incentive, think about what that program can leverage, and perhaps think about the people who will be participating in it and how much money they have to bring to the table. An art grants program would work on a one-to-one match, but your chances are much better if you have two-to-one or three-to-one.
It doesn't have to be money; a lot of these groups get in-kind services. They know the guy who owns the bulldozer on his farm, and he will take it over and help them with their conservation project. There are creative things that can be put into the implementation section of the plan.
