The selection of suitable provenances is essential for achieving maximum productivity in forest plantations. As few countries have the resources for provenance testing over a wide range of sites, a thorough appraisal of the relative merits of different provenances can only be achieved through international cooperation and exchange of information. The establishment of the Pinus caribaea Morelet and Pinus oocarpa Schiede international provenance trials under the coordination of the Commonwealth Forestry Institute, Oxford, led to the creation of a provenance assessment data base which revealed that certain provenances grew well in a wide range of environments across countries.
