Abstract
A natural burn occurred in the Deep Well area of McKenzie Flats in June, 1995, following which studies were initiated to evaluate the effect of fire on plant species composition and the spatial and temporal dynamics of regrowth. The burn area was approximately 24 hectares, forming a swath about 200 m wide from the initial lightning-ignition source. The fire moved in a westward direction from the ignition point, leaving a relatively straight border along the southern boundary and an irregular edge along the northern boundary. The fire was extinguished naturally.One week after the burn, four 100 m line-intercept transects were established along the southern boundary of the burn. Transects were installed perpendicular to the burn, so that 50 m lay inside the burned area and 50 m outside, in unburned grassland. The first transect (nearest the road) was placed 100 m from the west end of the burn and identified as Transect A. The remaining transects (B,C,D) were located at 200 m intervals from Transect A. Rebar was placed at 0 m, 50 m, and 100 m and these points recorded with a GPS unit. Initial measurements were made in October, 1995. In subsequent years, measurements have been made in late May and late September to evaluate the response of "cool season" and "warm season" plant species. Another fire occurred on June 24, 2001. This burn only affected the unburned southern end of one transect. A prescribed burn in 2003 did not affect the transects.

Location: 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.).
