Description :
The aim of this paper is to test if relationships exist between directly measured soil water repellency, and the spatial and temporal variation in infiltration capacity and runoff generation on burned and unburned microsites within coarse-textured sagebrush dominated ecosystems. The most significant impact of fire was canopy and ground cover removal on coppice microsites. Fire-induced reduction in infiltration resulted from the combined effect of canopy and ground cover removal and the presence of naturally strong water repellent soils.
