Title:	Rainfall runoff and sediment deposition from 2 x 2 meter plots in grassland and creosotebush communities at the Jornada Basin LTER, 1982-1994
Alternate Identifier:	DOI PLACE HOLDER
Abstract:	This data package contains data from natural rainfall-runoff plots installed on lands managed by the Chihuahuan Desert Rangeland Research Center (CDRRC) and the Jornada Experimental Range (JER) during the early years of Jornada Basin LTER (LTER-I and II). The purpose of this study was to measure infiltration and runoff rates related to rain event duration and intensity, and soil and organic movement in creosotebush and grassland areas. In addition, some plots were treated with chlordane to remove termites. Nine hydrology runoff plots in the creosotebush sites (Larrea tridentata) were established in 1983 and 12 black grama (Bouteloua eriopoda) grassland runoff plots were established in 1989. Each plot was 2 × 2 square meters and surrounded on 3 sides by a metal frame. Rainfall was collected using a 10-cm diameter PVC pipe and a 120-liter tub. There are 4074 plot-events or observations in the data set. The data set includes the date of the rainfall event, relative cover of vegetation, sediment concentration in runoff (mg/l), precipitation (mm), deposited sediment, and percent carbon. This study began in fall 1982 and was completed in fall 1994.

Description:

This study was conducted on lands managed by the Chihuahuan Desert Rangeland Research Center (CDRRC) and the Jornada Experimental Range (JER). Runoff plots were located in 3 areas of creosotebush and two areas of black grama (Bouteloua eriopoda) grassland. The creosotebush site is located on the Jornada LTER exclosure at Mt. Summerford and is dominated by Larrea tridentata. This site contains termite treated plots (CT, 1-5), non-treated control plots (CC, 1-4), and caliche layer plots (CL, 1-4). CT plots were treated with chlordane to remove termites. Grassland site, GS, contained 4 plots and is located on the alluvial piedmont of Mount Summerford, where runoff drains eastward. The second grassland site (GI, plots 1-4) were located to the north of Mt. Summerford at the IBP (International Biosphere Project) grassland exclosure. Attempts were made to examine plots after each rain event (but not more frequently than 24 hours) to determine if runoff occurred, however some samples may represent more than one precipitation event.

Each plot was 2 × 2 square meters and surrounded on 3 sides by a metal frame that prevented overland flow from crossing the area of study. Overland flow generated by precipitation falling on the plot itself was collected along the downslope edge using a 10-cm diameter PVC pipe split lengthwise to channel the discharge into collection buckets. Runoff from small events was collected in a 19-liter bucket; runoff from larger events that overflowed this bucket were collected into a subtending 120-liter tub. At each site, an 8.00 inch (20.32-cm) diameter tipping bucket rain gauge was used to measure the incident rainfall associated with each runoff event. Each plot was chosen based on initial relative plant cover, where each site had at least 2 plots with low cover and 2 with high cover. Relative plant cover was measured as bush or higher (B) or as no bush or lower (N). In the creosotebush sites, the low cover (N) plots, contained little to no herbaceous and subshrub vegetation and no creosotebush. Runoff volume derived from individual precipitation events was measured for 7 years (1988–1994) in the shrubland and 5.5 years (1989–1994) in the grasslands. The data set includes the date of the rainfall event, relative cover of vegetation, sediment concentration in runoff (mg/l), precipitation (mm), deposited sediment, and percent carbon. This study began in fall 1982 and was completed in fall 1994.
