The research of the small mammals in the Chenky forestry area was done during the summers in 2004–2008. There have been worked 16400 snare-24hours and caught 1077 small mammals of 9 species in total. There has been given the estimation of the species variety and the numbers and the biotope spreading of the species to be researched have been analyzed. The dominant species in all the biotopes has been Сletrionomys glareolis, whose maximum relative plenty was registered in 2006 (7,67 species per 100 snare-24hours). The single case, the only once registered species in our research has been Crocidura leucodon, Sorex minutes. There has been also determined the increace in the species variety of small mammals in proportion to the removal from the zones of the anthropology impact with the almost invariable numbers at the same time. The researched biotopes are characterized by a different extent of the anthropo-logy pressure, what is reflected on the numbers and the fauna diversity of small mammals.

Key words: small mammals, biotopes, anthropology impact, species variety.
