This is kind of a thing, at least at the county level. The county I live in has an annual sapling/seed sale where bunches of Minnesota-appropriate saplings are sold at low cost (average $25 for 2 dozen tree saplings) along with packets of various types of prairie grass and wildflower mixes. My main problem is laziness, so a lot of my plants end up dying before I get them in the ground, or I forget to take care of them after I do. I've planted a bunch of seedlings from the program over the last 10 years and a couple are already over 12' tall. I planted about a half-dozen swamp oaks last year and most of them are doing fine so far.

Part of the problem (as always!) is people. There is the Roadsides for Wildlife program, meaning that the county will not spray herbicide in areas with the sign in order to promote wildlife habitat. But a lot of people will take the signs down. I guess because "dandelions ugly."

Since my "lawn" is already mostly clover and other wild plants anyway, I'm definitely going to look into this program.
