Red List Indicator; endangered animals and plants

This table gives an overview of the extent of the threat to animal and plant groups in the Netherlands in 1995, 2005 and annually from 2013. This is done by comparing the “color” of the so-called Red Lists. A Red List is a list of endangered plant species or species with the extent to which it is endangered in its survival. When the threat increases, the “color” of the list “roder”/dark, if the threat decreases less “red”/lighter. The “color” is actually the total number of steps that the endangered species together are away from the unthreatened status, where a step is the transition from a Red List status to the next status to a greater or lesser degree of threat. For example, a change from status ‘vulnerable’ to ‘Fentile’ status is one step in the right direction (+ 1); a species going from ‘vulnerable’ to ‘Seriously endangered’ takes two steps towards extinction (-2). The colour of the 1995 Red Lists is set to 100, each time looking at the same collection of species on the Red Lists from 1995. A value 104 in 2005 means that the threat has increased by 4 % compared to 1995. The degree of threat of a species in a given year is derived from the rarity in that year and the trend from 1950 to that year. More information on this can be found in this explanatory note under ‘Sources and Methods’. Status of the figures: The figures are final. Amendments as of 23 June 2022: The figures for 2021 have been added. When are new figures coming? The next update will be released in June 2023.
