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
Research demonstrates that the regeneration of key native flora, specifically drooping she-oak (Allocasuarina verticillata) and sweet bursaria (Bursaria spinosa), cannot occur when rabbit densities are at or above 0.5 rabbits per hectare.
Density of European Rabbit (Oryctolagus cuniculus) per hectare at which regeneration of key native flora is inhibited.
This benchmark represents the density of European Rabbit above which regeneration of key native flora in arid shrublands and stony plains agricultural crop production areas is prevented.
This threshold is supported by ecological research in arid South Australian ecosystems indicating a critical density of 0.5 rabbits per hectare.
