A Note on Termite Hills

Abstract

In the drier areas the soil is lighter and less compact and a mound with less steeply sloping sides is formed. The typical appearance of the countryside is that of stunted and sparse tree growth with ample scope for wind action in the open spaces which are inadequately protected by grass, etc. The termite mounds here tend to provide a resting place for the organic residues blown from the open tracts. Bird and animal droppings and seeds are not so rapidly washed away. These factors give vegetation on the mounds a slight initial advantage which once cover is established, is of course cumulative. Finally the slightly raised situation gives the vegetation some immunity from fire.
