Orr Branch
Orr Branch is a roughly 2-mile (3.22 km) creek in the White Rock/ Trinity River watershed in eastern Texas. From its uppermost source near the intersection of Tibbs and West Ricks Circle streets, it runs northeast through a portion of suburban Dallas until it flows into White Rock Creek (of which it is a tributary) and ultimately feeds into White Rock Lake. History From the end of the Pleistocene Epoch and into historic times, the Texas blackland prairie surrounding Orr Branch supported scattered herds of bison and (prior to European contact) the Indian tribes who utilized bison as a resource. In north central Texas, these tribes would have included the Kitikiti'sh ( Wichita), Comanche, Caddo, and Cherokee. By the mid-19th Century, cattle and other livestock had replaced the bison. Prairie grasses and forbs were vital forage for Texas Longhorns and other breeds being moved north along the ancient trace that came to be known as Preston Trail, the present-day Preston Roa ...

Prairie Soil
Prairies are ecosystems considered part of the temperate grasslands, savannas, and shrublands biome by ecologists, based on similar temperate climates, moderate rainfall, and a composition of grasses, herbs, and shrubs, rather than trees, as the dominant vegetation type. Temperate grassland regions include the Pampas of Argentina, Brazil and Uruguay, and the steppe of Romania, Ukraine, Russia, and Kazakhstan. Lands typically referred to as "prairie" (a French loan word) tend to be in North America. The term encompasses the lower and mid-latitude of the area referred to as the Interior Plains of Canada, the United States, and Mexico. It includes all of the Great Plains as well as the wetter, hillier land to the east. From west to east, generally the drier expanse of shortgrass prairie gives way to mixed grass prairie and ultimately the richer and wetter soils of the tallgrass prairie. In the U.S., the area is constituted by most or all of the states, from north to south, of North ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
