Rocky Mountain PEER covers the states of the Rocky Mountain region. These states contain millions of acres of federally protected lands. These unique areas, which include Yellowstone National Park, Arches National Monument, the Maroon Bells-Snowmass Wilderness Area, Grand Teton National Park, and Rocky Mountain National Park, bring countless visitors to the breathtaking landscapes that define the Rocky Mountains. Major environmental issues facing the region include habitat protection, roadless forests and wilderness areas, urban and suburban sprawl, and water issues.
Chandra Rosenthal, a Colorado native, heads up the office as Rocky Mountain PEER Director. Chandra, formerly staff attorney with Defenders of Wildlife specializing in endangered species and public lands issues, has also worked for the U.S. Department of Justice and, under a legal fellowship, worked on a Superfund site with the Department of Energy.
“I view my job as helping the region’s public service professionals do their jobs of protecting the diverse and abundant natural resources of the Rockies,” states Rosenthal.
