As part of phase 1 financed by the Guadeloupe Water Office, La Déal, the Guadeloupe Region and the Guadeloupe National Park. 80 species present in a natural environment along a river were pre-selected by the group: National Forestry Office, BRGM and the TAUARI design office. During phase 2, the project team tested the characteristics, mechanical properties and reproductive capacities of around forty species out of these 80 pre-selected and potentially usable in plant engineering. The results are presented in our research work.
