Ludwik Lipnicki

Abstract


The first regional list of threatened lichens and allied fungi is presented. The list is a result of investigation studies in the Tucholskie Forest, lowland forests growing in Western Pomerania, in northern Poland. 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 data obtained were compared with historical ones. Changes of species main frequency were used as an additional indicator of their threat status. The Red List includes 151 taxa of lichens, lichenicolous and saprobic fungi, which constitute 39.7% of the local biota and 9.4% of Polish biota. The status of threatened biota has the following categories: Regionally Extinct (RE) - 28 taxa, Critically Endangered (CR) - 4, Endangered (EN) - 28, Vulnerable (VU) - 26, Near Threatened (NT) -19, Least Concern (LC) - 9 and Data Deficient (DD) - 37.
