Abstract


The first regional list of threatened lichens and allied fungi is presented. The list is a result of investigation studies in Gdańsk Pomerania, which mostly comprises the area of the Pomeranian Voivodeship and geobotanic units of Gdańsk Pomerania in Poland. The data obtained were compared with historical ones. Changes of the species main frequency were used as an additional indicator of their threat status. The status of threat to the lichen and allied fungi species listed has been determined according to the Red List Categories by IUCN (2001, version 3.1). The Red List includes 286 taxa of lichens, licheniclous and saprobic fungi, which constitute 53.9% of the local biota and 17.9% of Polish biota. The status ofthreatened biota has the following categori-es: Regionally Extinct (RE) - 37 taxa, Critically Endangered (CR) - 45, Endangered (EN) - 44, Vulnerable (VU) - 82, Near Threatened (NT) - 5, Least Concern (LC) - 6 and Data Deficient (DD) - 67. Species typical of deciduous forests are the most threatened ones.
