• The edaphic environment in the colonies of the common cormorant (Phalacrocorax carbo) was investigated to detect the effects of cormorant's defecation on plants through the soil. Some properties of the soil down to 50 cm depth in the cormorant's colonies in Chikubu Island and Isaki Cape (Lake Biwa, Shiga Pref., Japan), were compared against those of the soil on the outside of the colonies in 1992. On the inside of the colonies, soil acidification over the whole soil layer, which has been considered to accelerate the accumulation of toxic ions such as Al^<3+>, and increase in moisture content at the depth of 5 and 15 cm, which would inhibit the growth of roots, were recognized. Thus, plants in the colonies of the common cormorant were likely to suffer various negative effects through changes in soil environments mainly due to continual supply of faeces onto the ground.
