Red List

The goal of Red lists - at the global, national, or regional level - is to illustrate the current threat situation of species; therefore, they have to be updated regularly. They are an indispensable tool for anybody working in nature conservation and, in the form of additions to laws, they represent an important support for public authorities in the decision-making process.

 

Red List 2016

The Red List of the Swiss vascular plants was revised according to the guidelines of the International Union for Conservation of Nature (IUCN), and replaces the 2002 edition. Out of 2613 evaluated species and subspecies (taxa), 725 (28 %) are threatened (categories CR, EN, VU) or extinct (category EX/RE/CR(PE)), and an additional 415 (16 %) are near threatened (category NT). Compared to the evaluation published 14 years ago, the percentage of threatened taxa in the new evaluation is lower, but the Red List Index is lower as well. The decrease in the index is due to a higher number of extinct species and to many more near-threatened species. About 20 % of all taxa underwent a change in category. Among the habitats with the highest rates of threatened taxa are water ecosystems, banks and shores, dry grasslands, fields, and vineyards.

Abbreviations:
EX – Extinct = No known individuals remaining.
RE – Regionally extinct
CR(PE) – Possibly extinct.
CR - Critically endangered = Extremely high risk of extinction in the wild.
EN - Endangered = High risk of extinction in the wild.
VU - Vulnerable = High risk of endangerment in the wild.
NT - Near threatened = Likely to become endangered in the near future.

 

Red list index for all species and for species subsets from different habitats. Arrow direction indicates whether the situation has worsened (downward) or improved (upward).
