Tom, you are looking at a black and white photo, sand dunes in the desert, especially dry sand with cracks looks the same as your pictures. It is not"clearly" trees. If you see the pictures in true color you would see that it is just landscape. Yes there are lakes, but no trees. I could take a picture that looked exactly like the one you posted here on earth, in a place where no vegetation or trees existed.
If mars were covered with treesm someone would be able to see it and take a picture. Ameature astronomers would have picked this up a long time ago.
