Identifying land cover variability distinct from land cover change: Cheatgrass in the Great Basin
An understanding of land use/land cover change at local, regional, and global scales is important in an increasingly human-dominated biosphere. Here, we report on an under-appreciated complexity in the analysis of land cover change important in arid and semi-arid environments. In these environments, some land cover types show a high degree of inter-annual variability in productivity. In this st...
متن کاملRangeland Conservation Analysis # 2 Controlling Cheatgrass and Woody Species Invasion in the Great Basin
The Issue Invasive species, widely distributed across the western United States, pose critical conservation challenges on both non-Federal and Federal rangelands. Two of the biggest threats to ecosystem stability and integrity in the Great Basin (most of Nevada, a large part of Utah, and smaller sections of Oregon, Idaho, and California) are invasive annual grasses, particularly cheatgrass and ...
متن کاملSoil Polygenesis as a Function of Quai”eiinary Climate Change, Northern Great Basin, Usa
The Quaternary environmental history of the northern Great Basin is characterized by a combination of lower temperature and higher moisture than present. Using water-balance analysis of soils sampled along a climatic gradient, we demonstrate that long-term average effective moisture was about 2-4 cm yr-1 greater than present. Although this long-term average represents most of Quarternary time, ...
متن کاملRegional Surficial Geochemistry of the Northern Great Basin
The regional distribution of arsenic and 20 other elements in stream-sediment samples in northern Nevada and southeastern Oregon was studied in order to gain new insights about the geologic framework and patterns of hydrothermal mineralization in the area. Data were used from 10,261 samples that were originally collected during the National Uranium Resource Evaluation (NURE) Hydrogeochemical an...
متن کاملthe analysis of precipitation time regime in great karoon basin
â abstract â in this study by data of synoptic stations in karoon basin, the intensive showers with 1,2,6 and 9 hour duration have been extracted and the precipitation time regime has been evaluated by ranking method and non dimensional accumulation curve. in ranking method, first the showers of each time base have been divided to smaller periods and on this basis different periods of showers...
