Abstract:

Alterations to riverine ecosystems and the establishment of new man-made habitats along rivers have been accompanied by changes in vegetation composition and structure, which affect the birds inhabiting riparian stands. We examined the differences between bird communities inhabiting the relict growth of river meanders and those inhabiting secondary plantations along the Rivers Otava and Blanice (Czech Republic). In addition, we investigated whether the well-developed oak plantations on artificial fishpond dams, which are common in the studied landscape, might compensate for the loss of bird diversity following river regulation. Breeding bird community and habitat attributes were studied on 30 fixed-width line transects and analysed using Multivariate Redundancy Analysis. Relict meanders were the most structurally diversified habitat type, with the highest species diversity and the great richness of forest birds. In contrast, secondary plantations were the simplest stands with the poorest communities inhabited by more farmland species. Fishpond dams, though resembling the meanders more so than secondary stands, were found to be insufficient compensation for river meanders in regard to avian diversity. Supporting diverse plantations of softwood tree species and widening the narrow belts along river banks are highlighted as ways of managing riparian stands that are beneficial to birds.
