The proble 皿 of determining the nurnber of quadrats is considered in this paper . Asix meter b ア slx meter quadrat consisting of 36 units of l m2 vi 旦 yl sheets was set up in a beech stand of the

The arthropods fell and died on the sheets and were collected , The minimum unit area and its size were calculated b γ the application of the statistical theory to est 玉 mate the density and the biomass of the arthropods .
