Metrics for quantifying the contributions of different threats to Red Lists

Purpose

Improved quantification and reporting of threats affecting red-listed species or ecosystems, using the Red List Index or the Expected Loss of Species. Data from one or more Red Lists are needed as input.

The code described here

• is archived on Zenodo at doi:10.5281/zenodo.7843806;
• is used and explained in an article in Conservation Biology by Sandvik & Pedersen (2023);
• uses data available from Zenodo at doi:10.5281/zenodo.7893216.

Contents

The repository contains the R code to reproduce the findings of Sandvik & Pedersen (2023) as well as generic functions that can be used to analyse threats in other Red Lists:

• The functions used are defined in function.R.
• The specific analyses of the Norwegian Red Lists of species are shown in species.md (with the underlying R Markdown file available here).
• The specific analyses of the Norwegian Red List of ecosystems are shown in ecosyst.md (with the underlying R Markdown file available here).
• The changes from version 1.0 to 1.1. are explained in scopesev.md (with the underlying R Markdown file available here).
