The US Has Lost Nearly Half of its Historical Grasslands

The United States of America has lost about half of one of its most prominent and iconic landscapes; protecting what's left is key to ensuring healthy ecosystems and biodiversity in the future, experts told ABC News.

The continental U.S. has lost about half of its historic grasslands prior to European settlement, according to a press release from America's Grasslands Coalition, a network of conservation organizations, researchers and government agencies that aims to restore North America's native prairie and grassland ecosystems. An estimated 98 percent of native tall grass prairies has been eradicated, Ryan Sensenig, a grassland ecologist at the University of Notre Dame, told ABC News.

While grasslands are typically associated with the Great Plains, they used to exist in nearly every region of the U.S., Dwayne Estes, co-founder and executive director of the Southeastern Grasslands Institute told ABC News.
