The aim of the project "Habitats of amphibians in the agricultural landscape" is to conduct practical trials on how a landscape heavily influenced and used by human society needs to be structured in order to permit the long-term survival of amphibian species.
The detailed project objectives are
- to refine networking strategies and concepts for a (regional) network of amphibian habitats,
- to develop transferable planning principles which satisfy both the needs of users and the objective of a diverse, species-rich cultural landscape
- to devise specific guidelines and recommendations for action on amphibian conservation.
The geographical project region is the Drachenfelser Ländchen south of Bonn, an intensively-used agricultural landscape. Smaller but isolated patches of forest, some containing or adjacent to spawning waters, are surrounded by large swathes of agricultural land, busy roads and settlements. In respect of habitat types and forms of use, the region is thus a typical civilized landscape, and in its function as a representative landscape it offers conditions in which transferable results can be developed.
In addition to the four existing bodies of water in the area, in 1988 three further pools were created using plastic liners. The studies carried out in the period 1992-1995 as part of the scientific back-up successfully documented and analysed the dynamic first-colonization phase. After the existing spawning waters were thought to have reached an established and comparatively stable state after a period of about five years, the scientific back-up study was recommenced in May 2000 with the objective of delivering a concluding report.
The inclusion of studies in population genetics and linkage of the results to long-term field ecology data successfully enabled a comprehensive analysis of the population trends, genetic diversity and ecological stability of amphibians in the agricultural landscape. Thus the project should result in practical decision-making aids for nature conservation in the agricultural landscape, with potential for integrating the interests of conservationists and users of the natural environment.
