Can termites create islands?

Termites construct a wide-reaching network of corridors under their 13-foot-high hills, which ensures a high level of aeration of the soil. Through this tunnel system nutrients are transported upward from the deeper layers. For this reason the ground that surrounds termite hills is much more fertile than elsewhere. If flooding occurs the termites drown, but many green plants and bushes sprout from the fertile soil around their hills, thereby enabling small wooded islands to form.
