Abstract:

With the development of various plant conservation programs on the part of federal and state agencies, it can often seem bewildering to know exactly what the status of a given rare plant is, and how decisions are made as to whether a species should be included on a list of species of conservation concern. The objectives of this article will be to provide an overview of the coarse and fine filter concepts as they are applied to conservation of biological diversity; to discuss the ideas of rarity and endangerment; to describe the types of rare plant species that are found in Idaho on the basis of their geographic distribution patterns; and to quickly summarize the various lists of rare plant species that are used to address conservation concerns at different scales.
