Oribatid communities under 15 different vegetations were investigated in the campus of Yokohama National University, Yokohama, Central Japan. Some relation was found between species number of plants and that of oribatid mites. The highest density of the mites was not observed in the secondary forests under the least influence of human, but in the plantations. OA-index (Oribatei/Aeari×100) was higher in forests than in grasslands, and higher, among the forests, in the vegetations of higher in natural grade. Dominant oribatid species mostly consisted of cosmopolitic or ubiquitous species andhave no distinct relationwith plant communities. Analysis of oribatid communities by the method similar to that of phytosociology revealed a close relation between oribatid and plant communities.
