1 TERMITE MOUNDS CAN PREVENT DESERTIFICATION Corina E. Tarnita

2 Desertification due to: overgrazing; climate change

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

4 Termite mounds are islands of fertile vegetation

5 In Laikipia: black cotton soil termites

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

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

8 Thank you!
