In the grip of winter, the North American prairies can look deceptively barren. But many wild animals have evolved through harsh winters on these open grasslands, foraging in the snow and sheltering in dens from cold temperatures and biting winds.
Today most of our nation’s prairies are covered with the amber waves of grain that Katharine Lee Bates lauded in “America the Beautiful,” written in 1895. But scientists know surprisingly little about today’s remnant biodiversity in the grasslands – especially the status of what we call “big small mammals,” such as badgers, foxes, jackrabbits and porcupines.
Land conservation in the heartland has been underwhelming. According to most estimates, less than 4% of the tallgrass prairie ecosystem that once covered some 170 million acres of North America is left. And when native grasslands are altered, populations of endemic species like prairie dogs shrink dramatically.
Together, we have more than 60 years of experience using field-based, hypothesis-driven science to conserve wildlife in grassland systems in North America and across the globe. We have studied and protected species ranging from pronghorn and bison in North America to saiga and wild yak in Central Asia. If scientists can identify what has been lost and retained here in the U.S., farmers, ranchers and communities can make more informed choices about managing their lands and the species that depend upon them.
