Abstract:

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 consists of height measurements of soil on two set transects (NatReveg, 1933; Pasture8B, 1935). In 1933, about half of the NatReveg site exclosure was covered with mesquite dunes. Grasses dominated the nonduned portion, but mesquite plants were present. Approximately one-third of the NatReveg site exclosure was sprayed with 2,4,5-T for mesquite control in 1966-68. Further plot treatments were superposed upon the sprayed portion in 1969-72. The Pasture 8B site exclosure was established on an area where mesquite dunes were large and well established. The predominant soils in this exclosure are deep, loamy sands. Soil movement at these transects was measured by the distance between the soil surface and a notch in 50 cm t-posts located every 15.2 m (50 ft) The 1731-m Natural Revegetation Exclosure transect runs north-south through the center of the exclosure and extends 61 m (200ft) beyond the boundary fence on either end. It is located in primarily deep, loamy sand soils. The 457-m Pasture 8b transect is oriented WSW-ENE, and is located in shallower soils. These 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 for the most part replaced, with a new baseline notch height initiated on the posts. Data correspond to each year of collection, as well as measures of soil deposition or deflation during the intervals. This study was complete in 2011.

Design, treatments, and vegetation measurements

===============================================

This study was conducted on the Jornada Experimental Range (JER) from 1933-2011 and is described in detail in Gibbens et al. 1983. The study area is located on pasture exclosures in the basin where typic haplargids of the onite series and typic torripsamments of the pintura series dominate. Vegetation is dominated by large honey mesquite dunes (Prosopis glandulosa) and black grama grass (Bouteloua eriopoda). The Pasture 8B exclosure was established on an area where mesquite dunes were large and well established. Many seeding and transplanting trials were conducted from 1934-36 in unsuccessful attempts to establish forage grasses and browse species. In 1933, about half of the Site B exclosure was covered with mesquite dunes. Grasses dominated the non-duned portion of the exclosure but mesquite plants were present. To facilitate vegetation type mapping, a 201.1 X 201.1 m (10 X 10 chain) grid was laid out on the site Pasture 8B exclosure. Intersections of grid lines (81 points) were marked by steel fence posts. In February, 1935, the soil level at each grid point post was marked by filing a notch in the post 15.2 cm above the upper face of a 30.5 cm wooden ruler laid on the soil surface in a north-south direction on the east side of the post (Little 1935a). In I931, a 201.1 X 100.6 m (10 X 5 chain) grid was laid out on the Natural Revegetation (NatReveg) exclosure. Grid line intersections (153 points) were marked with a 1.2-m length of 3.2-cm pipe. Soil levels were marked, as described above, on the pipes in May, 1933 (Little 1935a). A re-measurement of soil levels at the grid markers was made in February, 1935 (Little 1935b). A transect was established across the NatReveg exclosure in 1935. Stakes 66 cm long cut from steel fence posts were driven 43 cm into the ground at 15.2-m intervals. The transects, which followed a north-south grid line 604 m from the west side of the exclosure, extended 61 m beyond the exclosure fence on the north and south sides. Soil levels were marked, on the 104 transect stakes in April, 1935.

For re-measuring, a metal detector was used to locate completely buried stakes. These were carefully excavated, preserving a reference to the current soil surface level.Frequency of re-measurement occured every 5 years except for after 2000 (1933/35, 1950, 1955, 1980, 1985, 1990, 1995, 2000, 2011).
