I'm trying to work up reward ideas for an upcoming Kickstarter campaign (for a plant database). For one of the rewards, I've currently listed planting a tree in the donor's name, probably in a region damaged by forest fires (appropriate species to the region of course). Theoretically, if I got a few dozen or more people, that's quite a few trees to put in the ground. But I'm wondering if anybody knows of any concerns, logistics, etcetera in doing something like this? Also, maybe somebody has an idea for an alternative thing to do, or better thing to do.
Another thought I had was to include some sort of harmless small plaque with each tree. Something harmless to the environment, that could stay with the tree. But I'm not sure how I might do this. I don't want it to be tied around the tree, then strangle the poor thing as it tries to grow (I don't know what effect it would have. I know it's not exactly girdling, but it can't be good)
I know I could probably contact the local forestry service to find out more, but I thought I'd toss the thoughts out here and see if anybody has comments.
