Predicting the water use and growth of Eucalyptus trees in Zululand

Abstract

HYDROLOGY “How much water does a Eucalyptus tree use?” This question is frequently asked of the CSIR Land Use Hydrology Group in Pietermaritzburg. Providing a concise and definitive answer is very difficult, since it depends on many variables such as the species and age of trees, their planting density, the availability of soil water, and weather conditions. A similar question might be “how much does a man drink?”, and we all know that this is a highly variable quantity!
