Madagascar shelters over 14,000 plant species, of which 90% are endemic. Some of the plants are very important for the socio-cultural and economic potential. Tampolo forest, located in the northeastern part of Madagascar, is one of the remnant littoral forests hinged on by the adjacent local communities for their daily livelihood. However, it has considerably shrunk due to anthropogenic activities forming forest patches. Thus, documenting the useful plants in and around the forest is important

Voucher specimens were collected following the information given by interviewees, (2) recorded the collection activities and the consumption methods through semi-structured interviews of the local inhabitants, and (3) performed a phytochemical screening to identify the active compounds and the potential healing metabolites of the medicinal plants. Results: A total of 65 people between 25 and 75 years old were interviewed. Surveys recorded 123 species used as timber, food, or medicine. Among them, 92 were forest species and 31 were ruderal species. Medicinal plants were mostly used to cure stomach ailments (71%), fever (33.3%), and fatigue (25%) with leaves (68%) being the most used plant part. Phytochemical analyses of 20 endemic medicinal species showed the presence of compounds that could be responsible for the therapeutic effects of the plants. Conclusions: Tampolo forest proves to be an important littoral forest highly utilized by the adjacent local communities due to the presence of a high number of useful plants which are mostly endemic to the region. Hence, our investigation assessed the importance of these species in the locality and this can be used for further study on ecology, conservation, and valorization of these species.
