This project was funded as part of the Columbia Basin Living Landscapes Program – a joint initiative of the Royal BC Museum and the Columbia Basin Trust. The purpose of the Columbia Basin Living Landscapes Program is to improve the understanding of the human and natural history of the Columbia Basin region of British Columbia. Key elements of the natural history of the basin are threatened due to human encroachment, accessibility, hunting, habitat loss or fragmentation, climate change, and a myriad of other reasons – many not well understood. Even the creation of protected areas does not ensure their survival.

This report identifies rare, threatened and endangered species of the Columbia Basin at the close of the 20th Century. Relevant information is provided on provincial Red and Blue-listed vertebrates, invertebrates, vascular and non-vascular plants, as well as a brief discussion of plant communities, exotic species, and protected areas. Distinguishing features, distribution, habitat, biology, population size, vulnerability and other pertinent information on species is provided, such as the reason for endangerment, if known.
