Vascular Plant Inventory of Mount Rainier National Park tabular data

Vascular plant inventory of Mount Rainier National Park tabular data, 2000-2007.The objectives for the vascular plant inventory were: 1) improve the quality of the species verification by increasing the number voucher specimens and 2) to verify the presence of sensitive plants that were listed as occurring within the park. The vascular plant inventory for Mount Rainier National Park was conducted between 2000 and 2007. Initially, the park had a vascular plant species list of 959 species, 56% of which were verified by herbarium specimens, 39% were documented by scientific studies, and the remaining 5% were unverified but were on the list based on species ranges. Our objectives for the vascular plant inventory were: 1) improve the quality of the species verification by increasing the number voucher specimens and 2) to verify the presence of sensitive plants that were listed as occurring within the park. Data mining was the first step of the project and involved in-person and on-line searches of 9 collections. Data mining located 1,099 specimens which increased the voucher-based verifications by 14%. Field inventories of undersurveyed areas and likely habitats of sensitive species were conducted from 2004 to 2007 in partnership with the University of Washington. These Botany Forays resulted in a final vascular plant species list of 973 species, verified at the 97% level: 74% by vouchers, 23% by scientific studies, and only 3% are unverified.
