Invasive Species Presence
Benchmark Value
Scoring Curve
This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context.
Evidence & Context
The ground layer is predominantly native (at least 50% of the perennial vegetation cover in the ground layer is made up of native species)?
Projective percentage cover of perennial native species within the ground vegetative layer.
Minimum proportion of native perennials required to resist invasive dominance in temperate grassy woodlands.
Represents the national regulatory benchmark for maintaining a native-dominated understorey in temperate grassy woodlands.
