In 2019, the Botany program at Crater Lake National Park received funds to repair visitor-use damaged landscapes immediately adjacent to the park’s Rim Trail. This project was planned to complement cyclical trail maintenance efforts, with the intent of restoring areas of trampled vegetation and compacted soils created by the numerous social trails and excessively large viewpoints along the length of the trail. Damaged areas identified within the project’s boundaries total over five acres. Work conducted in 2019 by the Botany program focused on project area assessment, revegetation (native seed collection and processing, plant propagation), and social trail obliteration. Results consisted of the partial development of a restoration framework; collection and processing of 12,127 g of native seed from three distinct seed collection zones; care of 2,569 containerized native plants propagated in fall 2018; sourcing propagation of an additional 4,746 plants; and a preliminary round of social trail obliteration at fifteen sites totaling approximately 0.7 acres.
