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 vegetative restoration of this impacted area, with a project length of three years. In the second year (2018) of the project, restoration efforts consisted of continued site monitoring; propagation of native plant materials from seed collected during the 2017 field season; soil rehabilitation; outplanting of plants salvaged from the area before it was disturbed; native seed collection, cleaning, and storage; and invasive vegetation management. Results of these efforts consisted of propagating 3,136 plants; outplanting 189 salvaged plants; collecting 2,587 grams of native seed; rehabilitating disturbed soils; and invasive vegetation management surveys which investigated 57 historic noxious weed population sites and documented and treated 13 current populations. Due to continued delays in the construction schedule, large sections of the project area were excluded from these restoration efforts and will be addressed during the 2019 field season.
