Three natural pine bog sites TR, NR and RhNR (see Ruuhijärvi & Reinikainen 1981, Lindholm 1981) in the mire Heinisuo were studied in 1980 with regard to certain parts of the soil fauna. Samples were taken monthly. The micro-habitats of the hummocks and hollows were treated separately. The results on animal numbers are presented preliminary. Nematods (Fig. 1) amounted to on an average 64 000—91 000 specimens/m2 in the uppermost 3 cm of the peat. There were no regular differences between the sites. Small amount of nematods was obviously due to too great sample pieces. Enchytraeids (Fig. 2) reached numbers of the same magnitude observed in other pine bog sites, 6 800—12 800/m2. There were less enchytraeids in the poorest habitat TR. The vertical and horizontal distribution as well as the seasonal fluctuation of enchytraeids were similar to those of the nematods. The occurrence of lumbricids and macro-arthropods (Table 1) showed greater differences between the micro-habitats than between the site types. The numbers were in general higher than those in the drier pine bog habitats IR and RaR (see Vilkamaa 1981, Markkula 1981).
