Abstract

Changing fire regimes and prescribed-fire use in invasive species management on rangelands require improved understanding of fire effects on runoff and erosion from steeply sloping sagebrush-steppe. The study area is located in the Reynolds Creek Experimental Watershed, Owyhee Mountains, southwestern Idaho, USA. Specific objectives were to quantify the relative contributions of runoff and erosion in rills and at small and large plot scales during concentrated-flow and rainfall simulations on burned and unburned sites and to evaluate surface-soil and vegetation factors that influence persistence of post-fire effects over a 3-year period. The data demonstrate that the persistence of fire effects on steeply-sloped, sandy sagebrush sites depends on the time period required for ground cover to recover to near 60 per cent and on the strength and persistence of "background" or fire-induced soil water repellency
