Hi,

Thanks for your questions! 

Check out this page of grant resources by Metro Blooms. You'll be able to eliminate some resources (focused on Twin Cities/residential), but there could be something useful there.

Check out this page by the Minnesota Native Plant Society.

It might be worth doing a pilot first - using ATV club member volunteers and donated plants - both to better understand the needs on a larger scale and to point to later as a demonstration when seeking funding or other kinds of support. Plant or seed donations could be solicited from a nursery or individuals. (If plants will be transplanted, make sure to read this guidance on jumping worms.)

Good luck - sounds like a good project!!
