This is really cool: Virginia has been having its citizens collect acorns and other seeds from a list of wanted tree species. You bring the seeds, (unfortunately they seem to be done for this year), they’ll get them started growing and then distribute the trees to replant formerly forested areas.
Here’s another one, for the DMV (Delaware/Maryland/Virginia) Potomac River area.
Found one for Sacramento, CA, and state-wide, here. Note that Re-Oaks specifies only acorns collected from within California, and that’s probably true of most states.
I wonder how many others have organizations like this?
