Species richness, extinction and immigration rates of vascular plants on islands in the Stockholm archipelago, Sweden, during a century of ceasing management

Survey of eighteen islands in the Stockholm archipelago from 1884–1908 was re-examined during 1996–1998 to investigate how island size, degree of isolation and human impact affect the species number, extinction and immigration rates of terrestrial vascular plants. Cattle grazing and haymaking was widely and commonly in practice on the islands, but became less intensive since the 1920s and ceased during the 1960s.
