Benchmark Value
Scoring Curve
The scoring engine could not generate a curve for this benchmark context. The primary form is CompositeFramework, but the benchmark data may be missing required fields (e.g., optimal range bounds for an OptimalRange benchmark). This is typically a data quality issue in the benchmark pipeline.

Evidence & Context
An ecological impact is likely occurring when rabbit density exceeds 0.5 rabbits per hectare (which equates to approximately one active warren per 10 hectares).
Density of key invasive herbivores (specifically European Rabbit) maintained below the ecological damage threshold.
This benchmark represents the ecological damage threshold for invasive herbivore density in production forestry within the Arid Inland Floodplains & Ephemeral River Systems biome, above which significant environmental harm occurs.
Scientific analysis has explicitly quantified this threshold as the population level above which significant environmental damage occurs, preventing regeneration of native flora including Callitris glaucophylla.
