Soil movement across black grama and mesquite ecotone transects in the Jornada Basin, southern New Mexico, USA, 1933-2011
<p>This package contains data from a study that measured long-term soil movement in areas undergoing mesquite invasion on the Jornada Experimental Range from 1933-2011. Data consist of height measurements of soil on two long-term transects established in the Natural Revegetation Exclosure (NatReveg) in 1933 and an exclosure in Pasture 8b in 1935. In 1933, about half of the NatReveg exclosure was covered with mesquite dunes. Grasses dominated the non-dune portion, but mesquite plants were present. Approximately one-third of the NatReveg site exclosure was sprayed with 2,4,5-T herbicide for mesquite control in 1966-68. Additional herbicide treatments were conducted upon the sprayed portion in 1969-72. The 1731-m NatReveg exclosure transect runs north-south through the center of the exclosure and extends 61 m (200ft) beyond the boundary fence on either end. The 457-m Pasture 8b transect is oriented WSW-ENE and was established in an area where mesquite dunes were large and well established. The predominant soils in this exclosure are deep loamy sands. Soil movement was measured by the distance between the soil surface and a notch in 50 cm T-posts located every 15.2 m (50 ft). Transects were measured in 1950 (8b only), 1955 (8b only), every five years from 1980-2000, and most recently in 2011. Most steel posts were re-measured at these intervals, but some were lost due to excavation or burial. These were replaced with a new baseline notch height initiated on the posts. Data correspond to each year of collection, as well as measures (in cm) of soil deposition or deflation during the intervals. This study is complete.For further information, see:Gibbens, R.P., J.M.
