Abstract
This study was designed to monitor the occurrence of various phenological events of plant species at seven research sites on the Sevilleta National Wildlife Refuge (i.e., Black Butte, Goat Draw, Five Points, Deep Well, Rio Salado, Sepultura Canyon and Los Pinos foothills watershed (Red Tank/222)). The phenological events monitored included germination, vegetative growth, budding (flowers), flowering, fruiting, dormancy, senescence, and death. All transects were placed close to Sevilleta LTER meteorological stations, allowing the coupling of biotic and abiotic data to detect relationships between climate and phenology.

Spatial coverage
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: 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.

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: This site is located in the foothills of the Sierra Ladrones on the west side of the Sevilleta NWR. Red Tank is a man-made earthen drainage pool and is the location of Met Station 43. Research conducted at the site includes soil moisture and erosion studies related to the Sierra Ladrone watershed project.Vegetation: The woody vegetation in this stream bed includes juniper (Juniperus monosperma), Brickellia californica, Apache plume (Fallugia paradoxa). On the hills are Junipers and shrubs such as cane cholla (Opuntia imbricata), beargrass (Nolina microcarpa), and Oreganillo (Aloysia wrightii). The herbs in the washes include Lesquerella ovalifolia, and Mirabilis multiflora. The grasses found at this site include three-awn (Aristida sp.), fluff-grass Erioneuron pulchellum, and four species of grama grass (Bouteloua spp.). , siteid: 12Location: 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 and 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.Vegetation: The vegetation of Deep Well Blue/Black Grama Mixed is Chihuahuan Desert Grassland, dominated by black grama (Bouteloua eriopoda) and blue grama (B. gracilis). Other grasses found at the site include dropseeds (Sporobolus spp.) and threeawns (Aristida spp.). Shrubs are uncommon but those that occur include Yucca glauca, Ephedra torreyi, and four-wing saltbush (Atriplex canescens). Herbaceous plants include Plantago purshii, Hymenopappus filifolius, and globe mallows (Sphaeralcea spp.).
