Project title: 
Assessing the Green Toad in Cologne according to FFH standards
ZFMK Project lead: 
Object of research: 
Amphibians, Toads


On behalf of the “Untere Landschaftsbehörde” a comprehensive inventory of the Green Toad (Bufo viridis) populations inhabiting the administrative area of Cologne was conducted according to FFH-ABC standards. Fieldwork was carried out in subsequent years (2012 and 2013). During fieldwork species specific habitat quality parameters were collected to evaluate habitat suitability for all study sites. Species distribution modelling approaches were used to predict the potential distribution of B. viridis across the administrative area of Cologne. Connectivity between populations of the Green Toad was assessed using connectivity models.
