In this paper we studied the Arctic habitats for quantitative microarthropoda that are key regulators of processes of mineralization and humification of plant residues. Dynamic performance numbers are mikroartpropod bioindicative indicators ecological environment of the Arctic habitat in general. It was found that the largest number of soil animals characteristic of the surface soil layer (0-5 cm) in which he observed the main focus of representatives of all groups (oribatid, collembola, other mites). As the dominant group was allocated - hard ticks (oribatid). The maximum population density of all microarthropods recorded in habitats with the highest content of organic matter (sedge-moss tundra (2500 ind./m2) and tundra with shrub-kladonievym community (over 1500 ind./m2).
