NCCN Inventory Exotic Plants Mount Rainier, North Cascades, and Olympic National Parks

Regina R. NCCN Inventory Exotic Plants Mount Rainier, North Cascades, and Olympic National Parks. 2001-2002. National Park Service

Exotic plant inventory in Mount Rainier, North Cascades, and Olympic National Parks, 2001-2002. The objectives for these inventories were to: 1) document exotic plant species that occur in susceptible habitats in each park, 2) describe distribution and abundance patterns of exotic plant species across vulnerable habitats, 3) identify habitats with the greatest exotic species richness, 4) identify patterns of exotic species richness with respect to elevation and distance from trailhead, and 5) identify priority exotic species for control based on biologic and management considerations. We surveyed 697 plots across the three parks and documented 112 exotic species in 348 (~50%) of the plots. We documented 42 species in MORA, 64 at NOCA, and 81 in OLYM. At all three parks, exotic species richness was generally highest in plots located in roadsides or developed zones. Our study documented 8 species that were not on the parks’ comprehensive online species lists (NPSpecies 2016): 2 at MORA and 6 at OLYM. Although we did not document any new species at NOCA, our study provided previously unavailable abundance information for that park.
