Abstract

Long term studies on faunal succession are urgently needed as they provide a basis for prognosis. In the last few decades the reduction in coal mining and steel production produced new types of manmade habitats (Rebele and Dettmar 1996). We studied the phenomenon of the effect of vegetation succession on animal communities in two different habitats and with two different animal groups: the birds of an urban park and the carabid beetles of a colliery spoil heap. In both habitats the faunal succession is measured by species turnover rate. In western central Europe, however, only a few monitoring studies of the avifauna of urban parks have been published (Nowakowski 1996), and the faunal succession of the carabid beetles of an urban colliery spoil heap has not yet been researched (before now). The Westpark covers an area of 10 ha and is situated 1.4 km from the city centre of Dortmund (51°30′N, 7°28′E) (NRW, FRG). The park was founded in 1811 as a cemetery and transformed after 1945 into a park; it now represents a piece of encapsulated nature surrounded by an extensive housing area. The dominant tree is ash (26% of the total trees), maple and birch are also present in abundance and, less frequently, oak, poplar, plane tree and horse chestnut can be found; some of these trees are about 100 years old. 18–20% of the vegetation is covered by shrubs, but most of the area is covered with intensively cultivated lawns.
