Medicinal plants have significant socioeconomic and health benefits, especially in developing countries with high poverty rates and limited health care coverage. However, the continuous utilization of medicinal plants without conservation efforts leads to species scarcity, especially for endangered species. This study, therefore, assessed the economic benefits and conservation status of medicinal plants in the Asukese and Amama Forest Reserves in Ghana. Field visits, structured and semi-structured questionnaires were used to survey 172 respondents focusing on their socio-demographic characteristics, medicinal plants used to treat diseases in the communities and plant parts used, preparation and administration of remedies, availability trend of medicinal plants, drivers of loss of medicinal plants, contribution of medicinal plants to gross incomes and conservation strategies. The study identified 143 plant species used to treat 135 ailments and diseases. The mostly highly cited plant family was Fabaceae (15 spp.). On average, medicinal plants contributed 64 % of gross annual income. Income from medicinal plants varied significantly across marital status and primary occupation but was similar across gender, religion, and educational levels. Thirty-three (33) of these plants were perceived to be threatened by over-harvesting, agricultural expansion, mining, logging, and climate change. Consequently, the cultivation of medicinal plants on farms, creation of medicinal plants nurseries, integration of medicinal plants in home gardens, creation of botanic gardens, and indigenous knowledge systems and practices were suggested as strategies for their conservation and sustainability utilization. There is therefore the need for increased conservation efforts to protect medicinal plant species from anthropogenic disturbance and the imminent threat of climate change. This will be critical for biodiversity conservation and sustainable economic development in local communities.
