What are tiers?

Tier 1

Estimate using own judgement and observations

Tier 2

Estimate using third-party professional estimates or public data

Tier 3

Model or measure based on site-specific surveys/sampling, remote or in-field sensing, laboratory analysis, etc.

Example data sources

Internal records

Third-party data sources

Maps showing records of occurrences of pest and disease-associated species species across Australia are available at the Atlas of Living Australia.

Site-specific measurements or model outputs

Data on invasive alien species (including certain pests and diseases) pressures on biodiversity in New South Wales are available at CSIRO Data Access Portal – Assessing invasive alien species pressures on biodiversity in New South Wales (exposure dimension): Data packages for the Biodiversity Indicator Program, first assessment.

Notes

‘Unaffected by’ could be defined more specifically as the flow of ecosystem services depended on by the reporting entity are not significantly reduced (remain above levels required to meet objectives), and/or management of this issue does not entail significant cost (above expectations).
Extensive information on weed species of relevance to Victoria is available at Victorian Resources Online – Invasive Plants.
