Welcome! Our research focuses on the impact of natural disturbances and global environmental change on mesic and arid grassland ecosystems. We are particularly interested in the interactive effects of fire, grazing and drought in mesic grasslands in North America and South Africa, and how rainfall variability, temperature change, and shrub encroachment affect aridland ecosystems in the southwestern US.


EDGE construction is moving along at SEV

Construction of our EDGE rainout shelters at SEV was completed this fall. Manufacturing the roof panels is underway and all sensors have been ordered! Shelters have also been constructed at the other study sites in Kansas, Colorado and Wyoming. Our goal is to be ready to start the rainfall manipulation treatments in April 2013.
