The grid method was used in the present study of the spatial structure of a gastropod community. 2,474 specimens representing 29 species were collected from an area of 9 sq m. The numbers of species we­re higher in squares with higher densities of snails (rNS = 0.9). Species diversity varied between the squares, ranging from about 2.6 to 4.1, and was not very closely correlated with increase in species number (rSH = 0.6). Snail density was not correlated with average dry litter weight in a square (rNM = –0.03). The values of the indices of Lexis and of Morista show that the distribution of snails in the studied forest patches was aggregated. The material suggests an obvious relation between snails and plants.
