Outline of Final Research Achievements

Whereas dryland forests are important as woody materials for local people, a great amount of water exploitation by forest trees has a serious effects on the local water balance. Investigation on the structure of natural forests and the growth and the water balance of artificial forests in dry land of Kenya revealed that the environmental condition in Kenya dryland could support big natural forest with high density and high biodiversity. Moreover, trees planted in high density could grow vigorously for long period. However, the amount of evaporation from forest floor was controlled by the condition of canopy and the amount of transpiration from artificial forest showed very high value in comparison with the annual precipitation.
