| Abstract: |
| This data set provides soil moisture data in each plot of the warming experiment (see
SEV176). Data are collected with automated soil moisture probes at 30-minute intervals
at two soil depths under grass and bare patches in each of the 40 plots.

| Study Area Name: Warming siteStudy Area Location: Within the Sevilleta, the site is
located just Northeast of Deep Well meteorological station. The site can be reached
by parking on the main road next to the signs for deep well and the minirhiztron study.
Note that the road to Deep Well met station does not permit vehicles. Travel on foot
towards deep well and look for a well-trod path off to the right shortly before the
met station. Vegetation: The vegetation is Chihuahuan Desert Grassland, dominated
by black grama (Bouteloua eriopoda and B. gracilis).North Coordinate:34.35946709South

| Geographic Description: |
Location: The Warming site is located just to the northeast of the Deep Well meteorological
station. The site can best be accessed by parking on the main road next to signs for
Deep Well and the mini-rhizotron study. Note that vehicles are not permitted on the
road to the Deep Well meteorological station. Travel on foot towards Deep Well and
look for a well-trod path to the northwest shortly before the meteorological station.
For plot maps, see power point slides in the on-line Sevilleta LTER WIKI page. On
August 4, 2009, a lightning-initiated fire began on the Sevilleta National Wildlife
Refuge. By August 5, 2009, the fire had reached the Warming site, which was burned
extensively though not entirely. Approximately 50% of plots burned on August 5 and
those plots which did not burn were burned within three weeks by US Fish and
Wildlife. Thus, the condition of all plots at the Warming site was comparable
by early September 2009.Vegetation: The vegetation is Chihuahuan Desert Grassland,
dominated by black grama (Bouteloua eriopoda) and blue grama (B. gracilis)., siteid:

| Method Step: |
| Description: |
| Experimental Design Our experimental design consists of three fully crossed factors
(warming, increased winter precipitation, and N addition) in a completely randomized
design, for a total of eight treatment combinations, with five replicates of each
treatment combination, for a total of 40 plots. Each plot is 3 x 3.5 m. All plots
contain B. eriopoda, B. gracilis and G. sarothrae. Our nighttime warming treatment
is imposed using lightweight aluminum fabric shelters (mounted on rollers similar
to a window shade) that are drawn across the warming plots each night to trap outgoing
longwave radiation. The dataloggers controlling shelter movements are programmed to
retract the shelters on nights when wind speeds exceed a threshold value (to prevent
damage to shelters) and when rain is detected by a rain gauge or snow is detected
by a leaf wetness sensor (to prevent an unintended rainout effect).Each winter we
impose an El Nino-like rainfall regime (50% increase over long-term average for non-El
Nino years) using an irrigation system and RO water. El Nino rains are added in 6
experimental storm events that mimic actual El Nino winter-storm event size and frequency.
From January-March, there are 4x5mm applications, 1x10mm application, and 1x20mm application.
During El Nino years we use ambient rainfall and do not impose experimental rainfall
events. For N deposition, we add 2.0 g m-2 y-1 of N in the form of NH4NO3 because
NH4 and NO3 contribute approximately equally to N deposition at SNWR (57% NH4 and
43% NO3; Bez et al., 2007). The NH4NO3 is dissolved in 12 liters of deionized water,
equivalent to a 1 mm rainfall event, and applied with a backpack sprayer prior to
the summer monsoon. Control plots receive the same amount of deionized water.Soil
moisture in each plot is measured at 5 and 15 cm beneath grass and bare soil using
10 cm ECH2O probes buried horizontal to the surface. Measurements are taken at 15
minute intervals.
