Propagation of Oregon's Rare and Endangered Plants
Linda C. McMahan
The Need to Conserve Native Species. Of the estimated 250,000 different kinds of plants on earth—species, subspecies, and varieties—over one in every ten is threatened with extinction in their wild habitats. Approximately 25,000 of these rare and endangered plants are in the continental United States, Hawaii, and Puerto Rico. The Pacific Northwest has 250 to 300 of them.
In 1984, a national organization called the Center for Plant Conservation (CPC) was formed to use the resources of botanical gardens and arboreta to help conserve rare and endangered native plant species. The Berry Botanic Garden was one of the charter participating institutions for the CPC, and is responsible for the plants of our region, including Oregon, Washington, and northern California. We are joined by 19 other botanic gardens, including the Missouri Botanical Garden, New York Botanical Garden, the University of California at Berkeley Botanical Garden, and the Rancho Santa Ana Botanical Garden in Claremont,
