By building dams and preventing flooding we have seen some trees like maple begin to invade the river edge habitat. As succession occurs in these habitats trees like the cottonwoods and willows lose out and are replaced. Back away from the river we see clearcutting and other disturbances that have left the habitat scarred. So, species richness and abundance are changed. Describe the potential cummunity interaction between trees, mosses, and ferns.
Mosses grow just about anywhere that it is wet enough, including on trees.
Ferns are epiphytes and do not grow in soil, but they cannot simply grow on the trees since they can't sink their roots into the bark. If there is moss on the tree the ferns can sink their roots into it. So, whereever the moss grows it provides potential habitat for ferns. Describe the sequences of events that occurs during succession. After a disturbance pioneer species quickly invade and colonize the area.
