Abstract
This file contains mark/recapture trapping data collected from 1989-2012 on permanently established web trapping arrays at 8 sites on the Sevilleta NWR. At each site 3 trapping webs are sampled for 3 consecutive nights in spring and fall. Not all sites have been trapped for the entire period. Each trapping web consists of 145 rebar stakes numbered from 1-145. There are 148 traps deployed on each web: 12 along each of 12 spokes radiating out from a central point (stake #145) plus 4 traps at the center point. The trapping sites are representative of Chihuahuan Desert Grassland, Chihuahuan Desert Shrubland, Pinyon-Juniper Woodland, Juniper Savanna, Plains-Mesa Sand Scrub and Blue Grama Grassland.

Spatial coverage
Location: 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.Vegetation: The Five Points Creosote site is characterized as Chihuahuan Desert Scrub, dominated by a creosote overstory, with broom snakeweed, purple pricklypear (Opuntia macrocentra), and soapweed yucca as co-occurring shrubs. The site is also characterized by numerous, dense, grass-dominated patches, reflecting proximity to the Five Points Black Grama Site. Dominant grasses are black grama, fluffgrass (Dasyochloa pulchellum), burrograss (Scleropogon brevifolia), bushmuhly (Muhlenbergia porteri), and galleta (Pleuraphis jamesii). Notable forbs include field bahia (Bahia absinthifolia), baby aster (Chaetopappa ericoides), plains hiddenflower (Cryptantha crassisepala), Indian rushpea (Hoffmannseggia glauca), Fendlers bladderpod (Lesquerella fendleri), and globemallows (Sphaeralcea spp.)., siteid: 3Location: 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. On August 4, 2009, a lightning-initiated fire began on the Sevilleta National Wildlife Refuge. By August 5, 2009, the fire had reached the Five Points Black Grama site. Portions of this site were burned, but not the entirety. See individual projects for further information on the effects of the burn. Vegetation: The Five Points Black Grama site is ecotonal in nature, bordering Chihuahuan Desert Scrub at its southern extent and Plains-Mesa Grassland at its northern, more mesic boundary. Characteristically, the dominant grass is black grama (Bouteloua eriopoda)., Location: 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 and 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 because the Small Mammal Exclosure Study's Larrea plots are co-located there. Rio Salado Grassland is the location 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. Vegetation: The Rio Salado Larrea site is characterized as Chihuahuan Desert Scrub, dominated by creosotebush (Larrea tridentata), with honey mesquite, fourwing saltbush, purple pricklypear (O. macrocentra), and broom snakeweed as co-occurring shrubs. Dominant grasses are black grama (Bouteloua eriopoda), galleta (Pleuraphis jamesii), burrograss (Scleropogon brevifolia), and fluffgrass (Dasyochloa pulchellum). Common forb species include desert holly (Acourtia nana), spectaclepod (Dimorphocarpa spp.), blackfoot daisey (Melampodium leucanthum), twinleaf (Senna bauhinoides), globemallow (Sphaeralcea wrightii), and plains hiddenflower (Cryptantha crassisepala). While individual creosote bushes tend to be larger, overall plant cover is less than at the creosote core site at Five Points, with more exposed embedded stones and gravel on the soil surface, creating a pavement-like appearance., Location: 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 and 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. Vegetation: The Rio Salado Grassland site is Plains-Mesa Sand Scrub habitat characterized by stabilized deep-sand dominated by coppice dunes of honey mesquite (Prosopis glandulosa). Co-dominant shrubs are sand sagebrush (Artemesia filifolia) and fourwing saltbush (Atriplex canescens), with winterfat (Krascheninnikovia lanata), Mormon tea (Ephedra torreyana), broom indigobush (Psorothamnus scoparius), soapweed yucca (Yucca glauca), and broom snakeweed (Gutierrezia sarothrae) as other notable shrubs. One-seed juniper (Juniperus monosperma) is present as well, especially along shallow washes. Compared to the Black Grama Core Site, grass cover is sparse and dominated by poverty threeawn (Aristida divaricata), Indian ricegrass (Oryzopsis hymenoides), mesa and spike dropseed (Sporobolus cryptandrus and S. contractus), as well as patches of black grama (Bouteloua eriopoda). Notable forbs included spectaclepod (Dimorphocarpa wislizenii), tansy aster (Machaeranthera tanacetifolia), desert marigold (Baileya multiradiata), Abert buckwheat (Eriogonum abertianum), dwarf gilia (Ipomopsis pumila), rattlesnake weed (Chamaesyce albomarginata), blunt tansymustard (Descarania obtusa), plains hiddenflower (Cryptantha crassisepala), and Rocky Mountain zinnia (Zinnia grandiflora)., siteid: 13Location: Ladron Foothills sites include Red Tank and Two-22 in the foothills of the Sierra Ladrones on the West side of the refuge.Soils: Soils in the Arroyo Riparian area are loose granitic gravel with many rocks and boulders., Vegetation: Two-22 site is characterized as Juniper Savanna/Arroyo Riparian (Dick-Peddie 1993). Two-22 trapping webs span 2 two vegetation types. The upland Juniper Savanna portion of the site is dominated by widely scattered, relatively small stature one-seed Juniper. Other shrubs are sparse, including scrub liveoak, skunkbush, tree cholla, pricklypear, and banana and soapweed yucca. Rocky open spaces are dominated by black, hairy, and blue grama. The lower Arroyo Riparian area consists of a more dense, more diverse vegetation, dominated by large specimens of scrub liveoak, one-seed juniper and Apache plume, as well as tree cholla, Engelman cholla (O. engelmanii), pricklypear, broom snakeweed, tarragon (Artemesia dracunculus), sacahuista, chamisa (Chrysothamnus nauseosus), fourwing saltbush, wolfberry (Lycium pallidum), and skunkbush. Grass diversity is relatively high and dominated by blue grama and bush muhly., Location: 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.Vegetation: The vegetation is New Mexico Pinyon-Juniper Woodland, dominated by Colorado pinyon (Pinus edulis) and one-seed juniper (Juniperus monosperma), and accompanied by gray oak (Quercus grisea). There is a diverse shrub component, including scrub live oak (Q. turbinella), mountain mahogany (Cercocarpus montanus), broom snakeweed (Gutierrezia sarothrae), sacahuista (Nolina microcarpa), red barberry (Mahonia haematocarpa), Apache plume (Fallugia paradoxa), tree cholla (Opuntia imbricata), skunkbush (Rhus trilobata), and banana yucca (Yucca baccata). Grass diversity is also high, and open spaces between trees are dominated by blue grama (Bouteloua gracilis), with hairy and sideoats grama (B. hirsuta and B. curtipendula) and black grama (B. eriopoda) also being significant. Other common grasses include purple threeawn (Aristida purpurea), wolftail (Lycurus phleoides), mountain and ring muhly (M. montanus and M. torreyi), and New Mexican porcupinegrass (Heterostipa neomexicana). Common forbs include small-flowered milkvetch (Astragalus nuttallianus), white sagebrush (Artemesia ludoviciana), Fendler’s arabis (Arabis fendleri), Fendler’s sandmat (Chamaesyce fendleri), New Mexico thistle (Cirsium neomexicanum), false pennyroyal (Hedeoma oblongifolia), bastard sage (Eriogonum wrightii), pingüe rubberweed (Hymenoxys richardsonii), large four o’clock (Mirabilis multiflora), Fendler's penstemon (Penstemon fendleri), and globemallows (Sphaeralcea hastulata and S. wrightii). , Location: The Goat Draw Juniper Savanna Core Site was established in 1998 in order to provide data at the lower end of the transition from the Pinon-Juniper Woodland habitat at the Cerro Montoso site to Juniper Savanna.Vegetation: While the site is positioned between two ridgelines, the vegetation is best characterized as Juniper Savanna, dominated by one-seed juniper (Juniperus monosperma), scrub liveoak (Quercus turbinella), and grama grasses (Bouteloua curtipendula, B. gracilis, B. eriopoda, and B. hirsuta), with scattered Colorado pinyon pine trees (Pinus edulis) in the upper reaches. There is also a significant influence of Arroyo Riparian vegetation in the main arroyo, Goat Draw, and its tributaries., siteid: 39Location: 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.Vegetation: Vegetation is characterized as Plains-Mesa Grassland, dominated by blue and black grama (Bouteloua gracilis and B. eriopoda) and galleta grass (Pleuraphis jamesii).
