Abstract: 

This primary purpose of this data set is to validate the LTER Weather Station tipping bucket rain gauge data. The dipstick rain gauge (DSRG) data is measured at least weekly during scheduled maintenance trips to the LTER Weather Station to maintain the evaporation pan water levels. During the summer months this may be twice a week.

Additionally, DSRG data is collected after any rain event that requires the collection of the Wetfall/Dryfall precipitation buckets which are located about 10 meters from the DSRG. This is usually any amount greater than 0.02". DSRG data is also collected after very small events when personnel are in the vicinity.

Abstract: 

Beginning in 1996, annual photos are taken from each of the 4 corners of each of the 15 70-meter x 70-meter NPP sites between August and November depending on other research activity constraints. The plots were established in early months of 1989. From 1996-2002 photos were taken using 35mm color slide film. Beginning in 2003, digital photos were taken in JPG format.

Occasionally, supplemental photos may be taken at the same time that provide additional habitat information at the landscape, patch, or plant species level

Abstract: 

A 4" diameter cylindric graduated rain gage (11" x 0.01" capacity) is mounted on a 4x4 inch diameter redwood post or on a wooden exclosure post next to gate at or near the 15 LTER-II NPP sites. Collection is made monthly on the day that monthly soil water content measurements are made to correlate precipitation input with belowground water content.

Data is collected primarily from graduated rain gauges. However, when missing data would result otherwise, amounts from the closest rain gauge are used in order to maintain as complete a data set as possible for that site. The rain gauge used is identified with each rainfall record. Other types that may be used are the Standard Can Gauge (DSRG or dipstick rain gauge), Belfort Weigh Bucket Rain Gauge (WBRG), and Qualimetrics Tipping Bucket Rain Gauge (TBRG).

Abstract: 

Daily summary values of averages of readings of the following parameters are made which are based on data recorded on a Campbell CR10(X) data logger: maximum, minimum, and average air temperature; maximum and minimum relative humidity; total precipitation; average wind speed; maximum wind speed; average wind direction; total incoming solar radiation; average soil temperature at 5cm and 20cm; me

an dew temperature. From 1983 - 5 June 1991, readings on which daily averages are based were made at 12 second intervals. From 6 June 1991 to present, readings on which daily averages are based are made at 10 second intervals.

Abstract: 

Soil water content measurements in the form of raw count readings are made at 5 depths at each of 89 (2" O.D. diameter) aluminum access tubes on the Control transect and at every 5th station on the nitrogen fertilized Treatment transect using a neutron probe (Campbell Model 503DR Hydroprobe). Access tubes are installed such that there are 6 inches of tube aboveground.

Stations are 30 meters apart. Measurements are taken at 30cm, 60cm, 90cm, 110cm, and 130cm. Neutron probe readings taken in 6 lysimeters along transects are also included. 5 standard readings are taken at beginning and end of each transect, and after every 20 stations. Measurements taken at 2 week intervals from April 1982 to 1987, monthly since.

Abstract: 

Average percent coverage of each plant species per 5-meter segment along a 30-meter line intercept perpendicular to each of 91 stations on each of the three LTER-I permanent transects. Data consists of week number, transect, station number, species, carbon reduction pathway, habit, form, and average percent cover. It is sorted by transect, station number, then plant species.

Measurements are made on 30-meter line intercept transects located perpendicular to each of 91 stations on each of the 2.7 km long Control, Treatment, and Alternate Control Transects established at the beginning of LTER-I. Following January 1, 1987, spring line- intercepts will only record cover of annual species. All perennial cover data will be limited to fall samples. Both annuals and perennials are measured during the fall. Measurements were made biannually from 1982 - 1988. After this they are measured every 5 years. Annuals are measured through 1998; however, after this only perennials are measured and only in the fall. Each plant line transect is divided into 6 5-meter segments. Annuals are measured only in the first meter of segments 1, 2, and 3 and in the last meter of segments 4, 5, and 6. Perennials are measured for the full length of all segments. BACKGROUND. In the spring of 1982, as part of the establishment of the Jornada Long-Term Ecological Research site in southern New Mexico, a 135 ha portion of a 1500 ha, internally drained, watershed was exclosed from grazing by domestic livestock. Prior to exclosure the watershed, as well as the rest of the Jornada basin, had been moderately to heavily grazed for the past 100 years. Concurrent with grazing, the vegetation had undergone a dramatic change from desert grassland, with an almost continuous cover of C4 perennial grasses, to isolated patches of the original grassland in a mosaic with desert shrub dominated plant communities (Buffington and Herbel, 1965). The exclosure lies along a northeast facing piedmont slope at the base of a steep isolated mountain peak, and covers a variety of component landforms from the foot of the mountain to the basin floor. This provided the opportunity to investigate the response of vegetation with respect to landscape characteristics as well as release from grazing.
