There is a large area that's cleared of all plants except for mosses what do you think happened?How do u know?

Answer 1

I think if you observed very closely, there are more plants there than mosses. Look for ferns and low-light wildflowers.

It could be too that there was some disturbance there (like a fire, etc.) that cleared out the major plants and then the mosses "pioneered" the site. Mosses, if give the right amount of light, moisture, etc., can be pioneers in the plant world. Mats of moss oftentimes seem to stabilize disturbed soil.

Answer 2

It may have been the area of a fire. Fires are a common way to clear lands, especially tall grass prairies.

Answer 3

Herbicide - guessing.

Answer 4

nothing too humid
