“…Many bunchgrass clumps and dalmatian toadflax rosettes were still green after burning and dalmatian toadflax rhizomes were generally below 10 mm of soil and not damaged by fire generated heat (Hayward 1938). It is doubtful that the thermal death point for plant tissue was reached during the fires (Write 1970, Wright et al 1976). …”

“…Previous vegetation mapping (Labor 1997) suggested that all study plots were similar in regards to dominant woody species and total woody plant canopy cover before application of burning treatments; however, pretreatment differences in species composition, especially less common (frequency of occurrence < 15%) species may have existed. Wright et al 1976, Cable 1965). Mesquite cover declined on both burning treatments but fire did not appear to induce significant mortality.…”

“…Ecological literature is rich in information about wildfire and prescribed fire effects on individual plant species where plant responses are typically measured with estimates of cover, biomass (Ansley and Castellano 2007) or individual mortality [the latter is particularly common with woody species (Wright et al 1976) and cacti (Vermeire and Roth 2011)]. At the plant community level in grasslands, fire impacts are usually measured by effects on forage production (Wright and Bailey 1982 and references therein)-that is, biomass is either harvested en masse (e.g., Scheintaub et al 2009) or by individual plants (e.g.…”

Abstract:Severe wildfires are increasing in extent in the western US. We used a matched-pairs design with plots in burned and non-burned areas to study effects of the East Amarillo Complex (EAC) wildfires on mixed grass prairie mean community composition and variability in composition. Species composition and ground cover data were collected at 5 study sites each year for three years following the EAC. Fire effects on mean species composition were analyzed with permutational analyses of variance; temporal patterns were analyzed with permutational anova and nonmetric multidimensional scaling; and an index of multivariate dispersion was used to assess variability in plant community composition. We found weak immediate impacts (year 1) of wildfire on mean species composition, but strong impacts by year three. Two general patterns of changes in mean species composition emerged: at 3 study sites, there was a progressive divergence in similarity between burned and non-burned areas following wildfire whereas at 2 study sites, wildfire effects lessened over time. In contrast, a trend of increased homogeneity in burned vegetation relative to non-burned vegetation was apparent at all 5 study sites 2 to 3 years post-fire; burned areas also had higher species diversity, higher evenness but similar species richness 3 years post-fire. Ground cover composition, which was immediately impacted by wildfire through removal of residual dry matter, was fully recovered to non-burned conditions 3 years after wildfire. We observed little seedling recruitment either of native or exotic species following wildfire. Community composition changes in burned areas were likely the result of changing dominance relationships among plants that survived the wildfires rather than the result of recruitment of new individuals in gaps created by dead plants. Given the growth form of perennial C 4 grasses and the fact that these grasslands evolved in the context of repeated fire, it is likely that changes in mean species composition and compositional variability are short-term responses.

“…Fire effects can be evaluated by collecting data on the intensity and duration of the fire or by observing fire parameters such as energy release, flame length, and residence time (Sapsis and Kauffman 1991). Ideally, this information is collected using thermocouples linked to data recorders (e.g., McDaniel et al 1997) or evaluated using time-temperature curves and fuel loading for a particular fuel type (e.g., Wright et al 1976). However, limitations imposed by study design, time, or other factors may make these methods impractical.…”

An experimental design required burn treatments for 10-m2 circular plots. We constructed a fire enclosure for the plots using sheetmetal, electrical conduit, and other commonly available materials. We field tested the enclosure in sagebrush-grass ecosystems in central Nevada and central Utah, and evaluated peak fire temperatures using small metal tags striped with temperature sensitive paint. We obtained average peak surface temperatures of 310, 307, and 381° C in bare ground, under grass, and under shrub microsites, respectively, for the Nevada sites and 253, 299, and 337° C for the same microsites, respectively, in Utah. Subsurface (2-cm depth) temperatures rarely exceeded 79° C, the lowest temperature detectable by our method. The enclosure contained the fire and did not permit escape of any embers or firebrands. The fire enclosure, burn technique and temperature monitoring method used are inexpensive, easily deployed, and desirable for experiments where larger-scale burns are impractical.Key Words: Fire, Great Basin, sagebrush, burn barrel, temperature, temperature monitoring Resumen Un diseno experimental requirio tratamientos de quema en parcelas circulares de 10 m2. Construimos una exclusion contra fuego para las parcelas utilizando hojas de metal, tubes metalicos para conduccion de cables de electricidad (conduit) y otros materiales comunmente disponibles. Probamos la exclusion en campo en ecosistemas de "Sagebrush-zacate" de la region central de Nevada y Utah y evaluamos las temperaturas pico del fuego usando pequenas etiquetas de metal marcadas con pintura sensible al calor. En los sitios de Nevada obtuvimos una temperaturas pico promedio de la superficie de 310, 307 y 381° C en suelo desnudo, bajo el zacate y en los micrositios de los arbustos respectivamente, en tanto en Utah registramos 253, 299 y 337° C respectivamente para los mismos micrositios. Las temperaturas subsuperficiales (2 cm de profundidad) raramente excedieron los 79° C, esta fue la temperatura mas baja detectable por el nuestro metodo. La exclusion contuvo el fuego y no permitio el escape de rescoldos ni llamaradas. La exclusion para fuego, la tecnica de quemado y el metodo de monitoreo de temperatura son baratos, facilmente desplegados y deseables para experimentos donde las quemas a gran escala son impracticas.The consequences and benefits of wildland fire have recently received greater attention from researchers and land managers, particularly in the western U.S. Effects of large wildland fires or prescribed burns can be examined without the use of experimental equipment at any spatial scale, but experiments at smaller (i.e., microhabitat) spatial scales often require control and monitoring of fire effects and environmental factors. In many of these experiments, it is necessary to restrict fire effects to small study plots, prevent disturbance of nearby control plots, maintain control of the fire, and ensure worker safety.
