Summary

This chapter is about active dunes. Most of the dunes examined here are features of the wide border zone between deserts, where almost all dunes are mobile, and areas where plant cover is complete enough totally to prevent the movement of sand. These border areas and the chapter share many dune forms with coastal dunes, where sand is supplied at a rate that competes with the growth of vegetation. If a dune is to be built around a plant, sand must blow, and the plant must grow. The interaction of these two processes, which determines the form of the resulting dunes, can be understood at six levels of complexity, including rigid objects, spatial pattern, porosity, flexibility, plant survival, and the broader time/space framework. The chapter ends with a discussion on Nebkhas dunes, blowouts parabolic dunes.
