In fragmented landscapes, like the porphyry landscape north of Halle (Germany), species are often faced with a set of suitable habitats of various size and isolation. An important issue in conservation biology is the design of nature refuges, which ensure the viability of populations. In community ecology, it is widely agreed, that the number of species increases with increasing patch size (e.g. Simberloff 1988). The predictive power of such species-area curves, however, is weak (Doak & Mills 1994).
