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. The scoring engine uses 3 benchmarks together — the Point form drives the primary score, while 2 guard(s) constrain the result.

Evidence & Context
The benchmark for Invasive Species Presence representing the best available condition in a production forestry context is a composite value: Absence of all species listed as eradication targets in the National Tropical Weeds Eradication Program and other key transformer pests subject to local eradication programs; AND <5% total foliar cover of other declared invasive plant species within the operational area post-harvest and during regeneration.
Presence/Absence criterion for designated transformer species and key pests subject to eradication or zero-tolerance policies AND a quantitative threshold (percentage cover) for all other declared invasive plant species.
A composite metric combining presence/absence of eradication target species and a percentage cover threshold for other invasive plants in tropical rainforest production forestry.
The benchmark is based on the principle of zero tolerance for transformer species and a low cover threshold for other invasives to maintain ecological integrity in high conservation value tropical rainforest production forestry.
