Most of the green you see on the forest floor in this picture are sugar maple seedlings that sprouted this spring. There are tens of thousands of seedlings per acre. What happens to all the seedlings? Well, most of them die.
You can see a few of the mature trees marked for harvest in the background. When the mature trees are cut, there will be a lot more light on the forest floor, and some of the maple seedlings will grow like crazy and turn into maple saplings. Here’s a natural gap that was created a few years ago by blowdown, and look at all those nice maple saplings. They sure look good.
