Prescribed Fire, Soil, and Plants: Burn Effects and Interactions in the Central Great Basin

“…5). The negative relationship between total soil N and exotic annual grass may seem to contradict research that suggests that cheatgrass is more competitive where N, particularly NO 3 À , is readily available (Kay and Evans 1965;Wilson et al 1966;Lowe et al 2003). However, sites with higher total N typically have finer texture soils and soil water holding capacity.…”

“…Many of these treatments tend to increase soil resources and may actually be facilitating exotic annual grass invasion (Prevey et al 2010). Much of the research surrounding annual grass invasion and sagebrushsteppe restoration has focused on soil water and N with significantly less attention being given to other nutrients and the interacting effects of abiotic factors (Kay and Evans 1965;Wilson et al 1966;Booth et al 2003;Lowe et al 2003;Monaco et al 2003;Vasquez et al 2008). The purpose of this research is to examine the set of vegetation, soil, and abiotic factors likely to influence resilience to management treatments (recovery potential) and resistance to cheatgrass in Wyoming big sagebrush (Artemisia tridentata ssp.…”

“…Cheatgrass responds dramatically to the availability of nitrogen, to the detriment of perennial plants, since it directly depletes nitrogen from the soil and interferes with N 2 -fixation by the biological soil crust (Kay and Evans 1965, Wilson et al 1966, McLendon and Redente 1991, Evans et al 2001. Although germination and root growth characteristics make cheatgrass a very aggressive plant, it tends to be most competitive with native vegetation after disturbance .…”
