Composite risk scores

Composite risk exposure scores for 103 Afro-Palaearctic migratory bird species. Scores are derived from sixteen anthropogenic threat layers calculated across species' breeding (br) and non-breeding (nbr) ranges, weighted by species-specific threat susceptibility scores and summarisied into into one of three risk types: direct mortality, habitat change and climate change. Dataset also includes a metric of migratory distance (km) and body mass (g).
