9.2 Species



To score species, experts will follow these steps:

  1. Estimate a consensus score for the condition of populations of the species in the Best 10% and Worst 10% of places where they occur (eg. relative to 1900).  Score both the area and condition of species; for example if it is estimated that the species is no longer found in 10% or more of its rage relative to the benchmark date, then the Worst 10% of that species will have a score of 1.

  2. Estimate a consensus score for the condition of the species in Most areas of the habitat (eg. relative to 1900).

  3. Assign a Confidence grade for the Condition estimates (High, Medium, Low).

  4. Estimate the trends for each of Best 10%, Worst 10%, Most (Improving, Declining, Stable) over the last 5 years.

  5. Assign a Confidence grade for the Trend estimates (High, Medium, Low).

  6. Identify the main anchor references, and any commentary/notes in any relevant column for the species.

 

Species

Grading statements for different species assessed, given what is best understood about their status and trends expressed in terms of populations and groups of species including threatened, endangered or protected species.

Very Good (7-8)

Only a few, if any, species populations have declined as a result of human activities or declining environmental conditions

Good (5-6)

Populations of a number of significant species but no species groups have declined significantly as a result of human activities or declining environmental conditions

Poor (3-4)

Populations of many species or some species groups have declined significantly as a result of human activities or declining environmental conditions

Very Poor (1-2)

Populations of a large number of species or species groups have declined significantly as a result of human activities or declining environmental conditions
