Why termites are important in rainforests during drought


January 24, 2019



What are termites doing when they’re not pests? Turns out they have a pretty important role in rainforest ecosystems.

A group of researchers revealed that termites were particularly beneficial to rainforests during periods of drought. The new termite research was published in the journal Science. The team of researchers set up an experiment during the El Nino drought in Borneo rainforests.

Turns out, termite activity doubled during the drought and actually helped increase the soil’s moisture. This means “termites were manipulating the water in the soil,” says Theo Evans, from the University of Western Australia in Perth and co-author of the research. “This is the first time this has been discovered.”

According to Discover magazine, Louise Ashton, an ecologist at the University of Hong Kong, says “We tend to think of termites only as pests, but they are also helping the maintenance of healthy ecosystems during periods of environmental stress.” With droughts in rainforests expected to be more common due to logging and climate change, termites will only be more important.
