The lichen biota of the Karnieszewice Forest Division (N Poland) is presented. Despite it is predominantly a strongly managed woodland area, 270 lichen species were found there including many rare species for Poland, as well as for European Low- land. Near 20% of the whole lichen biota are considered to be threatened in the country (categories CR, EN, VU), and 34 species are protected by law in Poland. Agonimia flabelliformis is reported for the second time from Polish lowlands. Key words: biodiversity, lichenized fungi, endangered species, Pomerania, Ascomycota, Basidiomycota, rare species.
