challenges of tree planting in wild?

Odd question...

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.

I would be concerned about wildlife mostly deer.....they are known for devouring young trees.....there are some deer resistant trees available if you do some research..that depends on your location however.......another thing I would do is try to find trees that like or need fire for survival....some trees like pitch pines (my area) need fire inorder for seeds to drop from cones.....this way the trees you plant wont be killed off by the next wildfire....plaques? perhaps make something out of concrete just use a mould and just before its dry use your finger to write the persons name in....then place it near the tree.

ahh.. good point on deer and other wildlife. I like the concrete idea. I'd want it to be relatively small and unobtrusive. Anything more would just detract from the forest.

I'm in Arizona, and would probably be planting somewhere up north in regions dominated by ponderosa, douglas fir, limber pine, apache pine and a few others generally. I'm not really versed on fire resistance. If I remember right, I imagine the ponderosa is the most fire resistant of these local species?

I can vouch for the deer. If they don't outright eat new trees, they rub them down to nothing when they are getting the velvet off their horns. I have been slowly planting apple trees at my hunting camp and have to surround each one with fencing until they grow up a bit. I reuse the fencing for the next round of trees. Just something to keep in mind. Otherwise sounds like a great idea.

Is there perhaps a minimum size that would increase the odds of deer-tolerance?

Well the bigger the better really.
