Predicting soil erosion and deposition effects on plant establishment:a key to increasing restoration success
Introduction Land degradation is frequently associated with soil erosion and deposition.This can result in significant modification of the soil profile,including changes in soil surface texture and structure.Soil surface texture and structure affect plant water availability through their effects on infiltration rate and plant available water holding capacity.Plants in arid and semi-arid environments are particularly susceptible to desiccation during establishment.Consequently,changes to soil surface texture,structure or depth can affect establishment,as well as the productivity of the established plant community.In extreme cases,re-establishment of the original plant community may be impossible,even with significant external inputs (Bestelmeyer et al.,In Press).
