Isolation of animal habitats due to roads and fields is well known from studies on Coleoptera. In 1986 - 1988 the carabid beetles (Coleoptera, Carabidae) and spiders (Araneida) inhabiting the area of Westerberg-quarry (Osnabruck, Lower Saxony) were investigated by means of pitfall traps. Results show that, despite a lack of typical isolating structures (e.g. traffic roads), Westerberg-quarry is a habitat island for carabid beetles but not for spiders. It is concluded that structures like footpaths, cultivated garden areas and cultivated public lawn areas surrounding the investigated quarry are also isolating barriers for Carabidae and the problem of urban habitat isolation is more imminent than is thought.
