摘要

Teak (Tectona grandis) was first introduced into Tanzania by the Germans in the late 19th century through seeds originating from the Calcutta region of India. This first introduction was completed by other provenances from South India until the First World War. Unfortunately, no further introductions and only little planting took place subsequently until the establishment in 1965 of the internationally renowned Longuza provenance trial, which has been noticeably depleted since then. This paper reviews the status of the existing teak stands mainly monitored by the Tanzanian National Tree Seed Programme, which set up the Kiroka teak clonal seed orchard in the rural district of Morogoro in 1996. Most of the teak stands in Tanzania are found in the foothills of the eastern mountain ranges and in well drained low-lying areas of sufficient rainfall inland where the conditions are suitable for teak. The private Kilombero Valley teak planting project, due to its particular characteristics, constitutes the topic of a special joint paper.
