Pacific Crest Well Pipeline Revegetation Project 2019 Annual Report

In 2017, Crater Lake National Park converted an existing exploratory groundwater well into a supplemental potable water source, the Pacific Crest Well. Development of pumping infrastructure and a transport pipeline created approximately 2.3 acres of bare-ground disturbance alongside a popular Park entrance road and regional transportation corridor. The Crater Lake National Park Botany program received funding to carry out restoration of this impacted area, with a project length of four years. In the third year (2019) of the project, restoration efforts consisted of continued site monitoring; care of plants propagated during the 2018 field season; native seed collection, cleaning, and storage; and invasive vegetation management. Results of these efforts consisted of collecting 1,414 grams of native seed; care of 3,235 containerized plants; and invasive vegetation management surveys which investigated 150 historic invasive plant populations and treated 27 current populations. Due to continued delays in the construction schedule, large sections of the project area remain excluded from restoration efforts and will be restored when possible.
