Abstract [en]

Loss of biological diversity is today a major global concern. One of the main reasons for this is loss and fragmentation of species habitat due to changes caused by humans. Therefore it is important to consider the impact on biological diversity early in physical planning. This report uses a method that could assist the prediction of effects on biological diversity during stages of physical planning, such as environmental impact assessment (EIA) and strategic environmental assessment (SEA). By modeling in Geographic Information Systems (GIS) using logistic regression, connections between observations of Red-breasted Flycatcher (Ficedula parva) and various environmental variables where made. The aim was to establish the preferred habitat type for the Red-breasted Flycatcher and thereby help biodiversity consideration in physical planning and conservation. Connections were confirmed between the Red- breasted Flycatcher and the variables old deciduous forests and edge zones around water areas and wetlands. This most likely means that the species prefers old deciduous swamp forests. In order to get more conclusive results, better variable data as well as improved observations are required. The study shows that with the required improvements this method has potential to be a useful tool for conservation planing.
