Ant fauna was studied on newly constructed ground and a secondary forest on the campus of the University of occupational and Environmental Health, Japan (UOEH), and in an adjacent natural forest in October and November of 1982. Collections of ants were made by honey bait traps and by hand sorting. Faunal analysis was made by the same procedure as is usually done by plant sociologists. In the natural forest (Symploco glaucae-Castanop-sietum sieboldii Miyawaki et al.) and in the secondary forest, Crematogaster osakensis Forel and Paratrechina flavipes (F.Smith) showed high constancy and high relative coverage, and Brachy-ponera chinensis (Emery), Aphaenogaster japonica Forel, Strumigenys lewisi Cameron, Weberistruma japonica (Ito) and Oligomyrmex sauteri Forel showed high constancy. On the abandoned grass-land, Paratrechina flavipes (F. Smith), Tetramorium caespitum (Linnaeus), Crematogaster osakensis Forel, Lasius niger (Linnaeus), lridomyrmex glaber (Mayr) showed medium constancy and low relative coverage. On the other hand, a newly constructed lawn was Inhabited by no or only a few kinds of ants, such as Tetramorium caespitim (Linnaeus), Formica japonica Motschulsky and Pheidole nodus F. Smith showing low constancy and low relative coverage. The ant fauna of shrubberies was the most plentiful among the sites studied. It contained lawn fauna, grassland fauna and fauna that originated from the marginal forest vegetation, which were carried with transplantation of garden trees.
