Evidence & Context

Lower Critical Threshold <20-30% (approaching bare ground) indicates soil highly exposed; significant risk of erosion (wind & water); reduced water infiltration; loss of soil moisture; impaired nutrient cycling; compromised seedling establishment.

Metric Definition:

Litter Cover (%)

Benchmark Definition:

This benchmark represents the lower critical threshold for litter cover in Australian Tropical Monsoonal Savannas under Production Forestry, below which significant ecological degradation occurs, including increased erosion risk and impaired soil health.

Justification:

Based on erosion risk and soil health degradation evidence from related studies.
