Island woodland and giant oaks
Svinö lies between the city and the Öland Bridge. Conifer forest, oak and flower-rich shore meadow meet a major bird route through Kalmar Strait. Blue spruce, eastern white pine and jack pine stand among native trees, probably planted when summer cottages occupied the island.
Horsö-Värsnäs includes former open pasture now largely returned to woodland. About fifty giant oaks remain. Rough bark and hollows filled with wood mould support lichens, birds, bats and wood-living insects, including hermit beetle.
When a harbour became bird habitat
Beijershamn on Öland began as a major nineteenth-century harbour project. The faulty basin silted up and was abandoned after only fifteen years. Shore meadow, reeds and shallow water took over; later clearance and renewed grazing helped restore one of the island’s finest bird sites.
Well over two hundred bird species have been recorded. More unexpected is the insect richness: 650 species of butterflies and larger moths, together with twelve bat species. Svinö, Horsö-Värsnäs and Beijershamn show planted woodland, ancient pasture trees and a failed industrial scheme developing into three very different habitats close to Kalmar.
