The present technical report covers the species trials in Uganda under the auspices of the EAC/NORAD Lowland Afforestation Project during the years 1971 to 1975. Only a few genera of the order Conijerae are indigenous in Africa and among those, the genus Pinus is not represented south of Sahara. A number of pine species have, however, successfully been established in that part of Africa and also in East Africa. Species like Pinus patu/a, P. radiata, P. elliottii and P. kesiya have proved to be easily established and fastgrowing and have been planted on a fairly large scale in the comparatively cool highland regions. Many more pines, e.g. P. taeda, P. massoniana, P. montezumae, P. michoacana, P. strobus, P. pseudostrobus and others, have also shown considerable promise on suitable sites. As long as planting areas were available in the East African highlands no serious attempts were made to establish plantations in the coastal lowlands. This may be the reason why the tropical (lowland) pines P. caribaea, P. oocarpa and P. merkusii (the latter maybe also because of being difficult to establish) were but little known in E.A. before the second halfof the 1950' s.
