WHAT THE EVIDENCE SAYS
GIS/RUSLE modelling across 3,402 square kilometres estimated annual soil loss from near zero to 51.4 tonnes per hectare, with higher modelled losses on steep degraded and intensively farmed slopes.
WHY IT MATTERS / OUR READ
Spatial risk surfaces can prioritize consultations and erosion-control reconnaissance rather than assign uniform prescriptions to an entire catchment.
CAVEATS / UNCERTAINTY
RUSLE produces modeled hillslope detachment, not field-measured sediment delivered to wetlands; conservative support-practice assumptions affect estimates.
