However, riparian areas and especially alluvial forests (AF) are poorly known in Finland and they have become increasingly rare. In this thesis the locations and species composition of AF were examined in Uusimaa region of southern Finland. I examined if the locations of AF habitat could be predicted with geographical information system (GIS) data and if the vascular plant and tree species compositions of AF differ from the other inventoried areas. In addition I was interested in the typical plant species composition of AF in Uusimaa. A masking was formed in ArcGIS program using open GIS-data that defines the potential areas for existence of AF. 10 potential AF sites were chosen by comparing the masking to aerial photographs. The vascular plant and tree species compositions of these sites were inventoried using 50 m long transects. These 10 inventoried sites included 6 sites which had at least one transect actually representing AF habitat. Transects were divided to 4 different types: island AF, mainland AF, mispredicted AF and control. The vascular plant species composition was different in every transect type when compared to other transect types. The AF vascular plant species composition in Uusimaa included deciduous forest species typical for the region and no indicator species were found. This thesis increased knowledge about the distribution and species composition of alluvial forests in southern Finland, which can be useful for e.g. authorities who work with the assessment of threatened habitat types in Finland.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2020-03-16T07:10:29Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2020-03-16T07:10:29Z (GMT).
