Impacts of grazing,wildfire and drought on rodent populations in a semi‐arid grassland of southwestern north America
Rodents are ecologically important vertebrates in semi‐arid grasslands of North America, both for their effects on plant community structure and because they support a wide range of predators.Previous work has indicated the importance of both livestock grazing and wildfire to southwestern U.S.rodent populations, but little is known about their possible combined effects.A 2002 wildfire burned both grazed and ungrazed grasslands in southeastern Arizona where rodent populations were being monitored, providing an opportunity to compare rodent responses to the interactive as well as independent effects of grazing and fire.
