The research is directed at the analysis of specific structure of communities of testate amoebae in forest habitats after the impact of fire. The objects of the re-search are communities of testate amoebae in pine for-ests of Yukseevsky forest area (northern border of Krasnoyarsk forest-steppe, Bolshemurtinsky area, Krasnoyarsk Region), one of which is control site, and two have undergone the fire (in 1996 and in 2006). In total 27 types and infraspecies taxons of testate amoe-bae have been identified, the most plentiful are: Cy-clopyxis eurystoma (14 % of the total), Trinema lineare (12 %), Trinema complanatum (7.5 %), Centropyxis orbicularis (7.5 %), Corythion orbicularis (7.1 %) and Euglypha rotund (6.6 %). The quantity of the types in communities varies from 7 to 19, the greatest specific variety is noted in moss tow and the top layer of laying (the subhorizon of L) of a pine forest mixed grasses (control site); least of all types it is noted in the subhori-zon L on ashes of 2006, here 10 years later after the fire in low-power laying types, characteristic for the organo-mineral soil horizons are fixed, the proportion of eury-biontic species Cyclopyxis, Trinema is high. High maintenance of cindery elements in the substratum of the burning biotopes promoted the development of the types of pedobionts: Centropyxis aerophila, Heleopera sylvatica, Difflugia penardi. Population density of testate amoebae varies ranging from 605 to 2738 shells on 1 g of air solid. The greatest density is observed in the tests of control site, and also the site burning in 1996 where the structure of communities comes nearer to initial, characteristic for laying of natural wood now With the help of Past 1-87b software the measure of similarity of types between trial platforms has been estimated and established that the restoration of structure of communi-ties of testate amoebae close to control is observed in laying of pine forests 20 years later after the fire.
