UAV data was collected in March 2018 and 2019, focusingon buffer areas of the natural mangrove forests adjacent to the guarding, along the estuary and plantedmangrove forests in Bai Trong. OpenDroneMap- as open source software- was used to mapping UAVimages. Research results showed that selected areas of the natural mangrove forests that have grownhealthy while the area of the planted mangrove forest in Bai Trong appeared to decrease quality, mainlyoccurred in Kandelia obovata. UAV routes, including height, distance between two Z turn-routes,shooting time that have remarkable influences on the success of the images mapping out of selectedmangrove forests. Therefore, UAV is applied as an effective tool support for managers, helping toquickly and precisely assess mangrove cover, especially in remote, isolated and hard-to-access areascompared to conventional field study approach.Keywords: Unmanned Aerial Vehicle- UAV, Mangrove forests, Xuan Thuy National Park.
