Abstract
The spread of invasive, particularily bird-sown and red-fruited, non-native woody species in open calcareous conifer forests in Sweden is discussed and examplified with a survey of pine forests by Åhus in E Scania, southern-most Sweden. The survey area is a pine forest planted ca 100 years ago on calcareous sanddunes within which an area with private homes with gardens was built in the 1960’s to 1980’s. The area has exceptional conservation values with recent occurences of 123 nationally red-listed species. No less than 112 woody taxa, of which all but ca 15 are garden escapes, were found during the survey. Large parts of the forest are now completely dominated by invasive non-native species, the most common being Cotoneaster bullatus, C. divaricatus, C. dielsianus, C. lucidus, Prunus mahaleb, Ribes alpinum, Amelanchier spicata, A. lamarckii, Berberis thunbergii, Mahonia aquifolium, Ribes sanguineum, R. uva-crispa and Taxus x media.
