Soil animal communities of planted birch stands in central Finland

摘要: The aim of this study was to compare soil animal communities in planted birch (Betula pendula) stands different origin with each other and natural forests. Six 30-year-old were investigated, three after clear-cutting spruce stands, on cultivated soil. faunal markedly plantations established forest arable “Birch Spruce” relatively similar those coniferous forests, though the population densities generally lower. Field” sparse could be characterised as “impoverished communities”, except Lumbricidae Enchytraeidae that have affinities deciduous forests cultural landscapes. Soil conditions are not sufficient explain differences between Colonisation transport by man may determine presence certain species, especially earthworms. These turn affect properties, compete or otherwise negative effects fauna. Thus community an outcome several factors: characteristics, site history, colonisation ability interspecific interactions.
