Calculate Biodiversity Intactness Index

This function calculates the mean biodiversity intactness index for a region.

The variable is the modeled average abundance of originally-present species, relative to their abundance in an intact ecosystem. Please refer to Newbold et al. (2016) for all details, and please cite it when using these data.

Usage

calc_biodiversity_intactness_index()

get_biodiversity_intactness_index(path = NULL)

Format

A function returning a tibble with the aggregated biodiversity intactness index.
