Multitaxa species richness of a wood-pasture complex in the Finnish SW-archipelago
Abstract
Traditional rural biotopes such as semi-natural grasslands and wood-pastures are among the most threatened biotopes in Finland. Archipelago Sea area hosts an especially representative collection of these biotopes, considering both their combined area and average quality. We surveyed birds, vascular plants, bryophytes, polypores and ground-inhabiting stipitate macrofungi in one wood-pasture complex in Korppoo, Archipelago Sea area. Here we report and discuss the results of these surveys. We detected altogether 457 species, including 8 red-listed bird species and 6 red-listed vascular plant species. We didn´t detect any red-listed bryophytes or fungi, but also these groups included several rare or indicator species as well as some fungal species not included in the latest Finnish red-list evaluation. The conservation value of this wood-pasture complex constitutes of species that are dependent on highly variable set of ecological conditions and habitats. This is related to highly variable conditions typical to wood pastures as a habitat.
