Evidence & Context

Sustained litter cover approaching 100% over extensive areas, indicative of very long fire exclusion, likely surpasses a detrimental threshold.

Metric Definition:

Litter Cover (%)

Benchmark Definition:

This benchmark represents the maximum litter cover percentage beyond which ecosystem functions and savanna structure are detrimentally affected due to very high litter accumulation.

Justification:

Based on evidence linking very high litter accumulation with inhibited plant regeneration, severe fire regimes, and negative faunal and microbial impacts.
