Management implications of bird responses to variation in non-native/native tree ratios within central European forest stands

Original language description

Plant invasions are a serious threat for global biodiversity and various studies have reported their impacts on forest bird populations. However, a majority of these studies involved comparisons of sites covered solely by invaded or native forest habitats, whereas the real world is dominated by habitat gradients. To address this issue, we counted birds in central European forest stands differing in the coverage of an invasive woody plant, Robinia pseudoacacia L., a major global tree invader. This species significantly affects the vegetation composition in invaded habitats, resulting in shifts in bird community compositions toward a dominance of generalist species at the expense of specialists. Here we ask: (i) how the bird species richness changes with the increasing relative coverage of R. pseudoacacia, recognizing several bird groups represented by all species, habitat specialists, habitat generalists and forest specialists, (ii) to what extent the alteration of vegetation composition accounts for these changes. By employing conditional autoregressive models, and by taking forest stand area and distance to the forest edge into account, we found that the numbers of all bird species, habitat specialists and forest specialists were highest in stands with intermediate coverage of R. pseudoacacia. This result indicates that the non-native tree was not detrimental for bird biodiversity, and that birds indeed benefited from its presence in focal forest stands, but only if native and non-native trees were present in approximately equal proportions, which was particularly true for forest specialists. The effect of R. pseudoacacia on bird species richness was significant even after taking changes in vegetation composition into account, suggesting that this invasive species affects birds not only by altering structural components of the habitat, but also by some other factors that might include food supply for birds or nest-holes.
