IMPROVE Calendars

IMPROVE sites are located in beautiful Class I areas: visibility protected national parks and national wilderness areas larger than 6,000 acres and 5,000 acres—respectively—and include lands managed by Native American Tribes, U.S. Fish and Wildlife Service, U.S. Forest Service, and the National Park Service. The IMPROVE calendars showcase these Class I areas with stunning images captured by AQRC/IMPROVE staff on location.
