Excerpt from Surveys of Springs in the Colorado River Drainage in Arches National Park, Canyonlands National Park, Glen Canyon National Recreation Area, and Grand Canyon National Park, Vol. 1: Final Report, February 2004The vascular plant ¿ora of the sampled springs comprised 125 native species and 19 exotic species. Beta diversity was high between sites, and jackknife estimates indicated the total native ¿ora of the site was likely under-sampled by with an estimated 159 species present. The majority of the ¿ora consisted of species with southwestern North America, widespread North America, or widespread temperate North America distributions. Additional data on distributions, pollination ecology, dispersal mechanisms, and growth forms is presented. A small Colorado Plateau endemic element of 12 species was documented, representing 10% of the native flora. T he fern Adiantum capillus-veneris and the orchid Epipactus gigantea were the most widely distributed species. T amarisk (tamarix ramosissima) was the most widespread exotic species. A variety of unusual and interesting relict species from other elevations and regions were found.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
