Home gardens are traditional agroforestry systems that promote plant diversity and ecosystem services while also having direct and positive impacts on human livelihoods. Even though home gardens are considered biodiversity hotspots and have recently been recognised as essential for their role in tropical biodiversity conservation, the benefits of ecosystem services provided by home gardens are understudied. This study investigated plant diversity and ecosystem services in tropical home gardens in the Aceh Timur region of Indonesia. Data was collected from 180 home gardens in 12 villages and recorded 173 plant species associated with 16 ecosystem services. The majority of the cultivated plants were fruit and vegetable plants, which played an important role in supporting food security and household income. Home gardens, with their plant species diversity and ecosystem services, played an important role in biodiversity conservation. Home gardens were important not only for improving household livelihoods, but also for the conservation of plant genetic resources and nearby protected forests.
