The Santa Clara River is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed March 15, 2011 river whose three forks join above Pine Valley in the Pine Valley Mountains in Washington County, Utah, United States. It flows west, then south, then briefly southeast before joining the Virgin River just south of downtown St. George. It is southern Utah's largest tributary to the Virgin River. History The river was named Santa Clara by the early travelers of the Old Spanish Trail that followed the river. It was also known as the Tonaquint River, for the Tonaquint Band of Indians who lived near the river's mouth. Archaeological evidence shows that Ancestral Puebloans (also known as the Virgin Anasazi) lived in the area from 700 B.C. to A.D. 1200 and that they had developed irrigation for their farmed crops. Their population increased until about A.D. 1200 when all Anasazi populations collapsed. They were replaced by the Sou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Threatened Species
Threatened species are any species (including animals, plants and fungi) which are vulnerable to endangerment in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of '' critical depensation'', a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment. IUCN definition The International Union for Conservation of Nature (IUCN) is the foremost authority on threatened species, and treats threatened species not as a single category, but as a group of three categories, depending on the degree to which they are threatened: *Vulnerable species * Endangered species * Critically endangered species Less-than-threatened categories are near threatened, least concern, and the no longer assigned category of conservation dependent. Species which have not been evaluated (NE), or do not have sufficient data ( data deficient) also are not consid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesquite
Mesquite is a common name for several plants in the genus '' Prosopis'', which contains over 40 species of small leguminous trees. They are native to dry areas in the Americas. They have extremely long roots to seek water from very far under ground. As a legume, mesquites are one of the few sources of fixed nitrogen in the desert habitat. These trees bloom from spring to summer. They often produce fruits known as "pods". ''Prosopis'' spp. are able to grow up to tall, depending on site and climate. They are deciduous and depending on location and rainfall have either deep or shallow roots. ''Prosopis'' is considered long-lived because of the low mortality rate after the dicotyledonous stage and juveniles are also able to survive in conditions with low light and drought. The Cahuilla indigenous people of western North America were known to eat the seeds of mesquite. History ''Prosopis'' spp. have been in North America since the Pliocene era and their wood has been dated to 33 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
