Dryland Ecosystems

Drylands are arid and semi-arid zones around the world where water resources are scarce. In the U.S., 40 percent of the land is considered dryland. USGS scientists are researching how predicted climate changes in dryland ecosystems--increases in temperature and declines in precipitation--will affect vegetation and wildlife in these areas as well as the ecosystem services they provide.
