Pumice Desert Revegetation Project 2019 Annual Report
Heisler SE, Wyler CS, Hooke J. 2020. Pumice Desert Revegetation Project 2019 Annual Report. National Park Service. Crater Lake National Park
In 2018, a visitor to Crater Lake National Park was cited for illegally driving 3.26 miles off-road through the park’s Pumice Desert area. The incident created large areas of deep, persistent ruts in the fragile pumice soil, killing most of the impacted vegetation within the tire tracks. Through the System Unit Resource Projection Act, the Botany program received funds to restore the damaged area to its pre-disturbance condition by smoothing out displaced soils, monitoring for invasive vegetation, and revegetating the area with locally sourced native plant materials through broadcast seeding and outplanting. Results of restoration efforts in 2019 include the development of revegetation prescriptions and plant material collection lists; collecting and processing 366 g of native seed; propagation of 396 native plants; smoothing out vehicle tracks; broadcasting 328 g of native seed; and monitoring for the establishment of invasive plant species.
