TERMITE MOUNDS CAN PREVENT DESERTIFICATION Corina E. Tarnita

Desertification due to: overgrazing; climate change

Sudden switch to desert; hard to recover Decreasing rainfall Increasing rainfall Rainfall (mm day -1 ) Vegetation biomass (g m -2 )

Termite mounds are islands of fertile vegetation

In Laikipia: black cotton soil termites

Termites:  Improve nutrients on mounds  Allow water to infiltrate better

Decreasing rainfall Increasing rainfall Vegetation biomass (g m -2 ) Rainfall (mm day -1 ) No mounds With mounds
