Hart Mountain National Antelope Refuge in southeastern Oregon encompasses 1,095 square kilometers of high desert. The refuge is administered by the U.S. Fish and Wildlife Service and had a significant amount of cattle grazing until 1990 when the cattle were removed. This abrupt removal of cattle provides a rare opportunity to see how ecosystems respond naturally with the cessation of grazing, a process termed “passive restoration”.
This project documents the restoration of Hart Mountain’s riparian systems through the use of repeat photography. Sixty four images from 1985-1991 were relocated and photographed in 2013 and 2014. These images are available to view and download in the images tab and are also viewable as part of an interactive map in the map tab.
