Abstract

Accelerated erosion by wind and water has taken place in arid western New South Wales since the introduction of domestic and feral herbivores by Europeans in the nineteenth century. This action led to widespread soil loss by sheetwash, rilling, gullying, and aeolian deflation. Radiocarbon dating of charcoal from Aboriginal cooking pits, exposed by this erosion, indicates that the current phase of incision of the valley floor has occurred since grazing of domestic animals began about 140 years ago. Channel enlargement and knickpoint retreat, initiated by these changes, is ongoing, and the implications of this for land and heritage management in the region are discussed. A conceptual model is presented
