This publication offers the foremost findings of a 12-year ecological learn of the Bornhöved Lake District, located a few 30 km south of Kiel. traditionally conversing, the current examine scheme, like similar long term atmosphere experiences at Göttingen, Bayreuth, München, and Berchtesgaden, has been conceived because the middle of a accomplished ecological surveillance method for Germany (Ellenberg et al. 1978). Comprising 3 interrelated elements, particularly an ecological tracking community, comparative atmosphere learn, and an environmental specimen financial institution, the program is meant to advertise either ecological technological know-how and making plans and coverage. during this connection the geo- and bioscientifically dependent surroundings learn goals at knowing the constitution and capabilities of structures, the average equilibrium and tension tolerance of singular parts and the total process opposed to adjustments and disturbances from inside and from outdoors, and the relationships among variety, productiveness, and balance. hence, environment learn kinds the crucial foundation for the rational research of the great information units made on hand by means of ecological tracking networks and for the enough collection of plant, animal, and soil specimens for environmental specimen banking purposes.

4 by their morphological, physical and chemical properties. 2 Groundwater The topographic catchment areas of the Bornhöved Lake District as shown on hydrological maps are only roughly suitable for water balance purposes since they normally differ from the subterranean catchments considerably as a consequence of the complicated hydrogeological situation. With the groundwater flow model MODFLOW (Guiguer and Franz 1997) and TWODAN (Fitts 1995), the subterraneous catchment areas as shown in Fig. 3 can be defined (Ruhmohr 1996; Kluge and Jelinek 1999).
Water flow and associated chemical fluxes between the lakes and their catchment areas are largely controlled by riparian wetlands which have, in terms of hydrological functions, the character of relatively small interfaces or ecotones with correspondingly increased hydrophysical and hydrochemical or biocoenotic gradients (Fränzle and Kluge 1997). Therefore, the research strategy along the banks of Lake Belau focused on analysing the hydraulically relevant alternation of mineral and organic soils (Schleuß et al.
