Spiders were used as a bioindicator of development on sites with birch stands in an air-polluted area. Changes in the number of spiders according to their size, niche, biotope and relicts are evaluated with the lapse of five years. Species of the 3rd and 4th size class, epigeal spider species, representatives inhabiting parallelly the epigeal and tree niche showed a dominant position in all locations under observation. In general, a decrease in the presence of exclusively forest species and non-forest spiders was observed, which was in common compensated by the presence of spiders inhabiting both forest and nonforest communities. Positive development on the locations with birch stands was determined by evaluation of spiders from their relicts.
