This was once a forested hillside. The county where this hill is located decided to widen the roads in the area. All of the trees and shrubs were cut down. This area was plowed up and all that was left was large boulders, gravel, and a thin layer of soil. After a year, left undisturbed, these low-growing plants appeared. If left undisturbed, what can we expect to see in this space a few years form now?

Unwanted/unplanned growth weeds will cover the whole area.

Explanation:

Because the area was previously forested hillside, it has all the environmental conditions (nutrients, rainfall, etc.) to support the vegetation. Hence, Although the soil layer is thin, natural weathering process would increase the depth of soil layer over the years. Later on, biogeochemical cycles on top layer will result into successful nutrients release to support vegetation. Hence, in a few years, there will be growth of weeds (unplanned vegegation).
