- Abstract:
- The hoopoe (Upupa epops) is a species which occurs in open habitats. The population decreased in the last decades. One reason may be the agricultural intensification. In southern Burgenland the population declined since the sixties as well. The aim of this study was to predict the occurrence of the hoopoe by habitat modelling using remote sensing information. A logistic regression model tests independent variables created in a geographic information system with reference to presence and absence of this species. In the area under investigation the hoopoe occurs only in settlement areas. This study should give information about the important habitats for this species in southern Burgenland. The sample consists of 22 hoopoe territories and 22 randomly chosen reference areas. The territory radius is assumed with 500 m. The variables used to predict the occurrence give information about land use, biomass, height of vegetation and aspect. The result is a model consisting of 4 variables. „Single trees in the open landscape“ is positive significant. This confirms the assumption that the hoopoe benefits from vertical structures by trees and shrubs. Single trees can offer natural breeding burrows, backing and can be used as singing vantage point. Furthermore the shadow impact can lead to areas with no or low vegetation under trees, which can be attractive foraging grounds for the hoopoe. Other variables about vegetation or aspect show no influence to the occurrence. The model can correctly predict 63,6 % of the sample as territory or reference area.
