Scoring Curve

Scoring curve unavailable

The scoring engine could not generate a curve for this benchmark context. The primary form is Point, 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

In EVC 43, the high benchmark for tufted graminoids (20%) reflects the "snow-grass" swards that define the alpine landscape.

Metric Definition:

Benchmark Cover (%) of Medium Tufted Graminoid (MTG) in Sub-alpine Woodland (EVC 43)

Benchmark Definition:

This benchmark represents the percentage cover of medium tufted graminoids in sub-alpine woodland, reflecting the characteristic snow-grass swards that define the alpine landscape and help maintain soil temperature and protect peat and organosols from erosion.

Justification:

Reflects the snow-grass swards that define the alpine landscape and maintain soil temperature and protect peat and organosols from erosion.

Notes

Critical for maintaining soil temperature and protecting delicate peat and organosols from erosion during spring snowmelt. No upper detrimental threshold — higher values are always better up to natural saturation.
