The main purpose of this paper is to discuss which plant species are endangered in the present mire vegeration in southern Finland. The work was realized using a 155 ha large, widely variable area of mire as an example. We compared the number of observed species in different abundance and distribution (frequency) classes and tried to identify the essential properties to describe a typical endangered species with the aid of three different niche characteristics: 1. trophic status, 2. depth to water table, and 3. mire margin — mire expanse -effect. For indicator values we have consulted earlier ecological literature. If we reject upland forest species, which accidentally appear in the mirevegetation, only species with a local scarce distribution were interpreted as endangered. The list of endangered species was broadly similar to earlier, subjectively composed lists. Most of the endangered plant species were associated with mesotrop-hic sites, on lawn or flark levels and with a mire expanse -effect.
