The microhabitat would be barren because it did not occur naturally.
The microhabitat would contain only a variety of grasses.

Weeds are plants that grow in areas where they are unwanted. Often they spread aggressively and damage garden plants by competing with them for sunlight, water, and nutrients. The growth of weeds is the first stage of ecological succession, which acts to —
restructure a habitat and allow only the most hardy plants to survive.
clear-cut a habitat and allow only the smallest plants to survive.
bring water to a habitat and allow only the most water-loving plants to survive.
drain water from a habitat and allow only the most fibrous plants to survive.
