Fire, Humans and Denudation at Wangrah Creek, Southern Tablelands, N.S.W.

摘要: The influence of altered fire regimes on the denudation a catchment is determined from alluvial deposits last 10,000 yrs and by monitoring runoff erosion before after wildfire. An increase in frequency beginning at 3,000–4,000 BP, as result intensified Aboriginal burning, did not change mechanisms or rates nor it cause widespread alluviation suggested others. results show that mild fires there insufficient most slopes to entrain sediment. Only intense are erodibility increased enough significantly accelerate erosion. Conditions then identified which likely lead accelerated other catchments.
