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
Proposed Threshold: >25% total projective foliage cover of perennial exotic invasive plant species.
total projective foliage cover of perennial exotic invasive plant species
This benchmark sets a maximum threshold of 25% invasive perennial exotic plant species cover in temperate dry woodlands and native grasslands under production forestry, beyond which significant ecological degradation is expected.
Represents significant competitive pressure and potential for accelerated spread/impact. Research on N. neesiana indicates invasion rates accelerate in poor condition sites.
