Can ter­mites cre­ate is­lands?

iD magazine - - Questions & Answers -

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.

HUGE OA­SIS Up to 150,000 is­lands built by ter­mites have arisen in Botswana’s Oka­vango Delta.
