Abstract
52 lichen species (30 epigeous species and 22 epiphytic species) were discovered in reclaimed sludge pits of 8 oil fi elds. Hypogymnia subduplicata is a new species for West Siberia and Gyalolechia fl avorubescens is a new species for KhMAO-Yugra. Frequency of occurrence for majority of lichen species is smaller than 20 %. Some lichens, for example Cladonia gracilis , C. cornuta , C. deformis, occur more frequently than other (frequency of occurrence exeeds 50 %). Some individuals of epigeous lichens in the area adjacent to oil production sites were dead. Th alluses of some epiphytic lichens were damaged and lichens were dying even in locations with reclaimed sludge pits.
