Hasty H, Hooke JS, Heisler SE. 2021. Invasive Vegetation Management 2020 Annual Report. National Park Service. Crater Lake National Park
Work performed in 2020 by Crater Lake National Park’s Invasive Vegetation Management program continued a steady 18-year effort to detect, contain, and reduce infestations of invasive plant species within the Park. The 2020 season marked the fourth year in which the Invasive Vegetation Management Plan was implemented, and the third full field season of Park-wide herbicide application. Using manual and chemical methods an estimated 112,328 invasive plants were treated in 2020. One new-to-the-park invasive plant species was discovered this year: sulfur cinquefoil (Potentilla recta) was found at Pole Bridge Creek Quarry, a staging area in the Park.
