To explore the native dry-zone woody flora of Central America and adjacent regions in order to identify potentially valuable species and provenances. * To make representative seed collections of these species and provenances for international distribution for the establishment of field trials to evaluate their relative performances in new environments. * To initiate measures to conserve the threatened genetic resource of these species.

The direct and indirect importance of trees to the livelihoods of rural communities in the Third World is an increasingly important consideration in many aid programmes. However, unlike industrial plantation species, those suitable for social forestry are relatively unknown. Many areas may benefit from species that are already recognised in their native environments as having useful qualities. Some, such as Calliandra calothyrsus, Gliricidia sepium and several species of Aacia and Prosopis have been successfully planted as exotics but usually on a trial and error basis. Inappropriate genetic material from unknown origin may result in the failure of some arid and semi-arid projects. Consequently, a systematic exploration and evaluation of the genetic resources of potential non-industrial species was required.

Résultats attendus
To explore the seasonally dry zone in Central America and collect seed of these species considered to have potential. Seed will then be distributed for establishment of field trials.
