Forest - Free stock photo

It is a stock photo that took a picture of a lot of trees that grow up richly on the slope in the mountain. Big trees are shaggily the space and grow up. Sunlight doesn’t stream so much ..these trees.. below in such a space’s there. I think that there will be a lot of insects. When the night comes, animals in the wild might be strolling, and it is scary somehow when imagining it.
There seems to be a little ..dark green color.. reddish ..thin.. color tree when often seeing though the tree is seen all things that looked like, too. Which kind of tree prospers most, and is there a power duel?
