Intactness

Overall biodiversity intactness

Species intactness index compares the predicted relative abundance of each species across the reporting region to the predicted abundance for that species under zero human footprint in the same region. This measure of intactness is scaled between 0 and 100, with 100 representing current abundance equal to that expected under reference conditions, and 0 representing species abundance as far from reference condition as possible. See more detailed description of the analyses and limitations in the methods section and in the intactness manual. Overall biodiversity intactness is the average of the intactness for each of the included taxa (birds, mammals, mites, native vascular plants, bryophytes, lichens). Each taxon is weighted equally, regardless of how many species it contains.
