ALBUQUERQUE—Cellulosic biofuels extracted from native switchgrass could lend a helping hand to imperiled birds that depend on vanishing prairies in the Midwest.
With palm oil plantations overrunning Indonesian rainforests and corn-based ethanol in the U.S. spurring new deforestation abroad, it may seem like biofuels and biodiversity don't mix. That's why ecologist Bruce Robertson at Michigan State University's W. K. Kellogg Biological Station and his colleagues wanted to know how birds and bugs would fare if the U.S. switches from corn-based ethanol production to cellulosic biofuels based on grasses. The U.S. Environmental Protection Agency is pushing these biofuels to help achieve further reductions in greenhouse gas emissions. Switchgrass has been singled out for biofuel production because of its low water requirements and high nutrient efficiency, along with the fact that it is native to the U.S.
