Summary

The object of the study was to determine the impact of human land use and drought on the density of trees in selected areas of Red Sea Province. five sites were examined during June and July 1989 for changes in tree density over the last 25 years. Density of trees was first counted from aerial photographs of the sites taken during the early 1960s then field work was carried out to determine the present density.

Tree density on the sites decreased greatly on three sites, decreased moderately on one site, and increased slightly on one site between the two time periods. Decline in tree density was due principally to human activities: charcoal and firewood production for market, land settlement, and land use intensification. Whatever impact recent drought may have had on the trees in the study sites was masked by human impacts. The author recommends that before any given land use development interventions are undertaken in Red Sea Province, research should be conducted to determine the long- and short-term environmental and social impacts of that development.
