Summary

This chapter is concerned with numerical changes in tree and grass populations. Size structure distributions of savanna trees vary widely, suggesting episodic recruitment is widespread. Life-history transitions of savanna trees are erratic and contingent on prevailing conditions, especially fire return intervals. Savanna trees vary widely in potential longevity, from several decades to thousands of years. Tree populations may be expanding or contracting in response to climatic variation or contingent influences. Grasses increase numerically through proliferation of either tillers, tufts or runners. Grass populations may turn over between one year and the next following drought or heavy grazing. Refuge sites enable grass species to persist through prolonged droughts.
