Arroyo Milagro is the site at which much of the Colorado pinyon (Pinus edulis) tree ring research was conducted on the Sevilleta LTER, as well as re-sampling of historic BLM 1976 vegetation transects, and juniper-creosote distribution. Most of the pinyons and junipers that were at this site died out in the 50's drought. This is the general area of Mesa Del Yeso, where there are extensive gypsum deposits.
The Blue Grama core site is one of five core SEV LTER study sites. Meteorological trends, rodent abundance, pollinator diversity, phenology, and NPP are all being investigated. Additional studies have examined the Bootleg Canyon fire of 1998 and subsequent effects on the patch dynamics of grasses.
Bronco Well is located near the northern boundary of the Sevilleta NWR, approximately four miles west of the AT&T on the road to Red Tank.
The BurnX study area is located on the southern end of Mckenzie Flats.
The Cerro Montosa Pinyon-Juniper site has been the location of major Sevilleta LTER research since 1989. Meteorological trends, net primary productivity, rodent and ground-dwelling arthropod populations, mycorrhizal responses to fertilizer, pinyon-juniper fruit and nut production, and pinyon mortality are all being investigated at this site. Previous studies have included analyses of pinyon tree rings for regional climate reconstruction.
The UNM Field Station and USF&WS Headquarters are the primary support facilities for all research conducted on the Sevilleta NWR. As such the area has also been important as a research site - especially as regards meteorology and monitoring of rodent populations for Hantavirus.
Five Points Black Grama is on the transition between Chihuahuan Desert Scrub and Desert Grassland habitat. The site is subject to intensive research activity, including assessments of net primary productivity, phenology, and pollinator diversity, amongst other projects. It is the site of the unburned black grama (GU) component of the Burn NPP study.
The Five Points area emcompasses both the Five Points Black Grama and Five Points Creosote study sites. Five Points falls along the transition between the Chihuahuan Desert Scrub and Desert Grassland habitats. Both core sites are subject to intensive research activities, including NPP measurements, phenology observations, pollinator diversity studies, and ground dwelling arthropod and rodent population assessments. There are rain-out shelters for drought studies in both the Five Points Black Grama and Five Points Creosote sites.
