Inventory of rare plant species in Theodore Roosevelt National Park

Heidel, Bonnie

THRO in southwestern ND is among the largest expanses of public lands and intact plains habitat in the Northern Great Plains. It is a living monument to the conservation philosophy expounded by Theodore Roosevelt. Management of THRO encompasses hundreds of native plant and animal species and their habitats. Special attention is given to plant and animal species considered endangered or threatened at federal or state levels, by way of surveying rare species resources, and directing appropriate monitoring, research, impact analysis and management(NPS 1984; Project Statements THRO-N-0015, 0008). The purpose of this project was to conduct a field inventory of THRO rare vascular plant resources and compile available information on their protection and preservation needs. Inventory work spanned the 70,416 acres of TRNP, including the South Unit with 46,346 acres, and the North Unit with 24,070 acres, lying within Billings and McKenzie Counties. This report includes information on each rare species documented in the park, including its park habitat, park distribution, park management concerns, close-up and habitat photographs, as well as state and global rarity status. This written report and accompanying maps, printouts, documentation and field forms are organized for information storage and retrieval needs as cited in Bratton (1981) with intent to keep them accessible and current.
