Dynamics of post-wildfire wind erosion of soil in semiarid rangelands,Idaho,USA

摘要：

Introduction Post-wildfire soil erosion by wind is an important but unstudied ecological process in cold desert,semiarid shrub steppe.In particular,the post-fire dynamics of soil erodibility are not well understood.We examined threshold wind speed during saltation events as a measure of erodibility for three months following a late-summer wildfire in southeastern Idaho,USA rangelands during 2007.Our objective was to describe variability and controls of erodibility throughout the first few months following fire,into the beginning of the winter period.
