Percentage of distribution area (calculated for each species separately) assigned to the five different threat levels (‘Very high’ to ‘No threat’) under this method. The three highest percentages per threat level are highlighted in bold. The species are ranked based on the percentage of distribution area under ‘severe threat’ (‘High’ and ‘Very high’ threat level).
