The various objectives of the Touho commune's environmental management plan are to inventory and map the floristic diversity of mangrove species throughout the commune, and to identify degraded mangroves. To this end, members of the Hô-üt association were trained in the identification of mangrove and back mangrove plant species, as well as in inventory techniques and the characterization of mangrove health. Field surveys consisted of recording a GPS point approximately every 50 meters within the Touho mangrove. At each point, participants made a 360° turn, noted all the plant species present, and characterized the state of health of the mangrove. The completed field sheets were then entered into the computer before being transferred to the consulting firm in charge of mapping. The latter then produced and delivered maps showing the distribution of mangrove species and their state of health, after GIS processing. The Hô-üt association then organized the presentation of this work to the customary authorities, the local population and the departments of the North Province.
