Abstract :
[en] The consideration of zoo-ecological questions in practical landscape planning frequently includes difficulties. The establishment of faunistic zoo-ecological contributions to landscape planning (e.g. landscape plan, impact regulation) often reveals deficits regarding inventory as well as analysis and evaluation. Habitat models allow to formalise the relationship between animal species and their environment. There have been numerous studies on habitat modelling as base for species protection in the open landscape, but only few studies have investigated this field in the urban environment. The study introduces an approach to evaluate urban structures on the basis of habitat modelling, applying data of faunistic surveys as well as generally available abiotic and biotic data. Using methods of geo-information and applied statistics (ENFA - Ecological Niche Factor Analysis) the urban structures are evaluated in terms of their habitat suitability for the two selected target species Green Woodpecker (Picus viridis) and Common Whitethroat (Sylvia communis). The ENFA allows both the calculation of the habitat suitability (HSI - Habitat-Suitability-Index) and the production of maps of habitat suitability (HSI maps). The identified HSI-values serve as a base for the evaluation of urban structures and hence support local planning decisions in urban and landscape development planning.
