Evidence & Context

The benchmark cover for this EVC reflects a high degree of structural layering, as illustrated in the following table: Medium Shrub 20%.

Metric Definition:

Percentage cover of medium shrubs in the understorey of Alpine Ash Forest (EVC 158)

Benchmark Definition:

This benchmark represents the typical percentage cover of medium shrubs in the understorey of Alpine Ash Forest within the Alpine and Subalpine Complex biome under pristine reference conditions.

Justification:

Derived from reference sites exhibiting minimal recent anthropogenic disturbance in the Highlands - Northern Fall bioregion.
