We are trialling a new concept called the biodiversity index.
The biodiversity index is a weighted score that provides an indicative value as to the general biodiversity of a given location.
The higher the number of threatened, rare and/or native species within a location, the higher it's biodiversity index will be.
Reporting more sightings of a species that already exists within a location will not influence its biodiversity index.
The biodiversity index for a given location is calculated by:
SUM ( weighted index of each species recorded at the location )
This is an initial attempt, or a starting point, to provide a consistent way to measure the biodiversity across different locations.
And I am certain that we won't have got it right first go.
The algorithm and weighted score used to calculate the biodiversity for each location is definitely open to feedback and improvement - but this is a starting point.
We are keen to see how it holds up and the kind of feedback that we get about this new feature.
Please comment below and let us know what you think!
The biodiversity index can provide a general indication that a location may either:
We would like to measure the change in a location's biodiversity index over time (both good and bad).
With 78 species of native orchids, open forest, woodland and grassland reserve, Black Mountain, has an extremely high biodiversity index:
In contrast, an urban area such as Dickson, ACT, carries a much lower biodiversity index:
