I went camping this weekend and I wont have the film back for a few days, but I noticed that A LOT of pine tree's up where I camp have had two rings cut in them about 18" off of the ground and into the tree about 3/4" all around the tree, all of the trees that had this also had some sort of boring insect into them so my guess is it was done to kill the tree while the insects where inside of it (I dont know why) anyway the hole the insects where making where about the size of a pencil lead and there would be several hundred holes like that in a 10' length of the tree (once I get the film back I will scan it and put a photo up) why would they cut the tree when the insects are in it? once the tree died wouldn't that just cause the insect to migrate to another living tree or would the insect larva need the tree to be alive to make it so by killing the tree you help stop the numbers of new insect? It is obvious that they have been fighting this battle for a long time cause there are tree's all over there that have died and lost the bark but are still standing or either hung up (a bunch of them) into other trees with these cuts in them.
