Evidence & Context
Upper Detrimental Threshold: >60%. Above this level, excessive litter accumulation becomes detrimental.
Litter cover is a crucial attribute of ecosystem health, influencing soil stability, moisture retention, nutrient cycling, and the structure of ground-layer habitat.
The maximum litter cover before accumulation becomes detrimental to biodiversity and ecosystem function.
Above this level, excessive litter accumulation physically suppresses the regeneration of critical native understorey species (especially forbs), can lead to soil acidification, and creates unnaturally high fine fuel loads, increasing the risk of high-intensity fires.
