Long-Range Ecogeomorphic Processes

Processes operating at larger spatial scales interact with those operating at smaller scales (discussed in the previous chapter) to produce spatial patterns in drylands. Hydrological processes operating at the catchment scale, the effects of grazing, fire, water and wind erosion are considered separately and in relation to their interactions with propagules and plants. The chapter concludes with a consideration of the extent to which feedbacks are central to pattern formation.
