The boundary zone between adjacent communities has long been recognized as a functionally important component of ecosystems (Odum 1959). The diversity and abundance of species (Noss 1983), the flow and accumulation of material and energy (Ranney et al. 1981), and the propagation of disturbances (Picket and White 1985, Turner et al. 1989) may all be affected by landscape boundaries. However, the spatial arrangement of different habitats and their boundaries has received little direct study (Wiens et al. 1985, Krummel et al. 1987). It is not surprising, therefore, that Hansen et al. (1988) have noted, “the extent to which landscape boundaries influence ecological flows is not well known and recent treatments of the topic remain speculative.”
