Scoring Curve

This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context.

Evidence & Context

This species was found chiefly in large (>100 ha), structurally diverse patches of vegetation (i.e. habitat complexity ≥ 8) with minimum habitat requirements of. > 20% tree canopy cover, > 10% shrub cover (0.5 – 4 m height), > 40% cover of native ground herbage, > 10% cover of fallen logs and >10% cover of litter.

Metric Definition:

Percentage of tree canopy cover evaluated at the patch scale.

Benchmark Definition:

Structural overstorey target required to support declining woodland bird populations within working agricultural landscapes under grazing management.

Justification:

Identifies the structural overstorey target required to support declining woodland bird populations within working agricultural landscapes under grazing management.
