biological indicator

any organism which can be used to characterize particular environmental properties, e.g. pollution, oxygenation. For example, crustose lichens, such as Leconora coneyaeoides, are tolerant of pollution, whereas fructuose lichens, such as Usnea sp., are very sensitive to atmospheric pollution and are found only in areas where pollution is slight.
