Alternate Identifier:DOI PLACE HOLDER
Abstract:

This data package contains biomass of annual and perennial forbs and grasses collected in grazing exclosures at fertilized and unfertilized transects at the Jornada Basin. The exclosure site was established in spring of 1982 and treatment transects were treated annually with NHNO3 at a concentration of 10g N/m2. Treatment application ceased in 1987. Biomass of annual and perennial forbs and grasses were then collected at control and treatment transects in 1989. This dataset consists of the date of collection, transect type, collection station, collection quad, plant species, dry weight, and quality of dry weight data. This dataset is complete.

Description:

Sampling design and laboratory analysis

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

This data was collected in 1989 as part of the Jornada Basin LTER program.

Starting in 1982, a 135 ha portion of a 1500 ha, internally drained, moderately-to-highly grazed watershed was exclosed from grazing by domestic livestock. Previous to this, the landscape had undergone a shift from desert grassland to shrubland as a result of grazing. Three parallel transects ran through the exclosure. Each transect is 30 meters wide with a 45 meter buffer zone between each transect. The Treatment transect was treated annually until 1987 with NHNO3 in a concentration equal to 10g N/m2. The station markers were placed at 30 meter intervals along each transect. Perpendicular to each transect and crossing at each station marker is the 30 meter plant line intercept transect. This extends 15 meters on either side of the station marker. The ends of the plant line intercept transect are marked by short rebars sticking up about 6 inches aboveground. The plant line intercept transects are thus perpendicular to the direction of major drainage flow.

Data was recorded by identifying the station number (metal tag located on fence post) and the segment number corresponding to those of the 30 meter plant line intercept running perpendicular to the main transect and station marker. The 5-meter segments are numbered 1 through 6 beginning at the west end of the line (right end if facing upslope). Biomass quads were located just downslope of the line intercept segments. One 1-meter section of the 5-meter segment was selected randomly for the 1-meter quadrat. Annual and perennial forbs and grasses were selected for biomass removals.
