4.There are many researches on rules of migration, foraging habits and breeding of egrets (Nycticorax nyticorax, Egretta garzetta, Ardea cinerea and Ardeole bacchus), however, there seems to be no report on ecological impact of its activity on the habitat. In the present paper, the ecological impact of egrets on the soil and trees of tea plantations was studied for the first time.
