Evidence & Context

"pre-disturbance stem densities calculated from remnants of previous populations suggest densities of between 24 and 240 stems per hectare according to site"

Metric Definition:

Stem density of mature snow gum populations before major modern disturbances

Benchmark Definition:

Represents the stable structural state of high-health snow gum woodlands in the Alpine and Subalpine Complex under livestock grazing.

Justification:

Represents the stable structural state of high-health snow gum woodlands.

Notes

Mature woodland stem density range before major disturbances. No upper detrimental threshold — higher values are always better up to natural saturation. AssessmentContext defaulted to 'Not Stated' because the source document did not state one.
