Crater Lake National Park’s Rim Drive Rehabilitation Revegetation project aims to mitigate impacts to the rim environment from the Federal Highway Administration-sponsored Rim Drive Rehabilitation project. This major construction project is correcting many deficiencies present along the Park’s historic Rim Drive and has been split into “Phases” encompassing iterative work progression. Work to date has fallen under Phase I of this project. Through surveying for and controlling invasive plant species, salvaging and reestablishing rare plant populations disturbed by the construction project, and restoring disturbed areas using site-specific native plants and seed it is hoped that long-term impacts from this construction project to the Park’s natural resources will be minimized. During the 2019 field season, over 920 invasive plants were removed from the project area. For the seventh year in a row, plant materials were collected from five distinct seed zones representing the floral diversity of the project area. Thirty-four seed accessions were provided to the Corvallis Plant Materials Center by Park staff for cleaning. Site documentation was refined for each disturbed site to inform future restoration efforts and monitor revegetation status of the project. In 2019, Crater Lake National Park staff planted 580 native plants, and dispersed 1,922 grams of native seed throughout disturbed areas along East Rim Drive. On West Rim Drive, 1,125 native plants were outplanted in disturbed areas and 9,565 grams of native seed were broadcast in disturbed areas along the road corridor.
