Mississippi Basin Carbon Project: Upland soil database for sites in Nishnabotna River basin, Iowa Mississippi Basin Carbon Project: Upland soil database for sites in Nishnabotna River basin, Iowa
The conversion of land from its native state to an agricultural use commonly results in a significant loss of soil carbon (Mann, 1985; Davidson and Ackerman, 1993). Globally, this loss is estimated to account for as much as 1/3 of the net CO2 emissions for the period of 1850 to 1980 (Houghton and others, 1983). Roughly 20 to 40 percent of original soil carbon is estimated to be lost as...

Recovery of perennial vegetation in military target sites in the eastern Mohave Desert, Arizona Recovery of perennial vegetation in military target sites in the eastern Mohave Desert, Arizona
The effect of the age of geomorphic surfaces on the recovery of desert vegetation in military target sites was studied in the Mohave and Cerbat Mountains of northwestern Arizona. The target sites were cleared of all vegetation during military exercises in 1942-1943 and have not been subsequently disturbed. The degree of recovery was measured by calculating percentage-similarity (PS) and
