The species composition and relative number herpetobiont spiders of the alder grove in the valley of Stugna River was investigated. 52 spider species from 12 families was noted, the dominant species was identified. Was established that spider family Linyphiidae is dominate by the species number – 16 (28.8%) and the spiders of the family Lycosidae is dominate by the relative density of specimens – 52,8%. The simultaneous dominance of the three species is revealed: Piratula hygrophila – 20% of the total number of individuals, Pardosa alacris – 19,9% and Pachygnatha listeri – 17,8%. The maximum value of the dynamics of species diversity (31 species), and dynamic density of spiders (80 ind. / 100 trap-days) was recorded in the third decade of May. The main part of the population of spiders is presented by mesophilic species – 39 (75%).
