| Abstract: |
| The line-intercept transects included in this data set have been discontinued. These
transects were installed to evaluate temporal and spatial dynamics in vegetation transition
zones (e.g.black grama grassland/creosote shrubland) at one centimeter resolution.
Each study site originally contained four 400 m transects, representing total coverage
of 1 sq km. The transects were placed along a roughly north/south azimuth. The northwestern
and southwestern transects were 100 meters from the western edge of the 1 sq km study
area and the northeastern and southeastern transects were 100 m from the eastern edge,
providing 800 meters between the eastern and western transects. The northeastern and
northwestern transects began to the north and, after an interval of 200 meters, the
southeastern and northeastern transects began, terminating at the southern edge of
the study area. Ongoing line-intercept transect data for transect 1, which continues
to be sampled at both Deep Well and Five Points, can be found in SEV004.

The Rio Salado is an ephemeral tributary of the Rio Grande on the west side of the
Sevilleta NWR, flowing west by northwest to east by southeast. Rio Salado Grassland
& Rio Salado Larrea are two study sites established in 1989. These sites were established as
counterparts to sites at Five Points. Between 1989 and 1998, vegetation, litter decomposition,
and ground dwelling arthropod and rodent populations were studied at both sites. Core
studies at these sites were largely terminated in 1998, although rodent populations
are still monitored at the Rio Salado Larrea site as the Small Mammal Exclosure Study's
Larrea plots are co-located there. Rio Salado Grassland is the location of Met Station
44. The Rio Salado study sites are accessed by taking the San Acacia exit, going west
and then taking the frontage road back north to the Sevilleta NWR gate. After entering
the refuge turn left after 0.2 mi and take this road 1.4 mi to a "T" in the road at
the power lines. An earthen berm stops road travel here and the met station is located
about 300 m west on the blocked road.

Sepultura Canyon is one of the largest ravines coming down from the Los Pinos Mountains
to McKenzie Flats. Originally a core site, rodent webs and vegetation line-intersept
transects were located in Sepultura Canyon through 1992, when the US Fish and Wildlife
Service established the Sevilleta Wolf Management Facility in the area.

Five Points is the area which encompasses the Five Points Black Grama and Five Points
Creosote Core study sites and falls along the transition between Chihuahuan Desert
Scrub and Desert Grassland habitats. Both sites are subject to intensive research
activity, including NPP measurement, phenology observation, pollinator diversity studies,
and ground dwelling arthropod and rodent population assessments. There are drought
rain-out shelters in both the Black Grama and Creosote sites, as well as the mixed-ecotone,
with co-located ET Towers.

Deep Well is located on McKenzie Flats and is site of the longest running SEV LTER
met station, number 40, which has been active since 1988. In addition to studies
of meteorological variables, core line-intercept vegetation transects and line-intercept
transects from the 1995 & 2001 Deep Well fires are sampled here. The mini-rhizotron
study, blue and black grama compositional comparison, blue and black grama patch dynamics
investigation, and kangaroo rat population assessement are all ongoing here. Deep
Well Blue/Black Grama Mixed is also the location of the warming and monsoon experiments,
as well as portions of the line-intercept and vegetation removal studies. On August
4, 2009, a lightning-initiated fire began on the Sevilleta National Wildlife Refuge.
By August 5, 2009, the fire had reached the area of Deep Well Blue/Black Grama Mixed.
While portions of this site were burned, the entirety was not. See individual projects
for further information on the effects of the fire.

| Description: |
| Changes to the data: This dataset (SEV200) includes all discontinued line-intercept
transect data files. In particular, data is included from Bronco Well, Valle de la
Jornada, Rio Salado and Sepultura Canyon, as well as transects 2-4 from Deep Well
and Five Points. Transect 1, season 2 data from Deep Well and Five Points in 1994
is also included (1994 was the only year that three seasons od data were collected).
Otherwise, SEV004 contains transect 1 data from Deep Well and Five Points. The data
in this file has not been rigorously QA/QCed. Old metadata and individual year data
can be found in: /export/db/local/htdocs/data/archive/plant/transect/data_oldformat.
This data will not be available online. See the Sevilleta data manager for data and
metadata in this old format.

| Method Step: |
| Description: |
| Measuring the Transects: A 100 m tape was attached to permanent pieces of rebar at
each of the four segments of a 400 m transect. The tape was stretched as tightly as
possible to get the straightest line. Windy days were avoided as this became impossible.
Crew members worked independently, each sampling a 100 m segment simultaneously. Microcassette
recorders and standard microcassettes were used to record data. At each 100m segment,
the following sequence was followed: Each species or substrate encountered along a
transect was recorded at the centimeter level. The distance at which a species or
substrate first crossed the tape was recorded. Starting points only were recorded
as the ending point of a species or substrate was the starting point of the next.
It was also noted whether vegetation was fully alive, fully dead or a mix of both.
