Recent advances in drone technologies have provided significant opportunities for providing detailed information on mangroves including:

• Extent of mangroves and proximal land covers as well as proportional information

• Plant species composition (primarily overstored)

• Canopy cover (overstorey)

• Canopy height (using stereo imagery; Otero et al., 2018))

• Change categories (e.g., disturbance, regeneration, dieback).

A number of drone datasets have been made available through the portal including:

• Drone aerial imagery, Kakadu National Park, NT

Drone data and derived products relevant to mangroves can be uploaded to the TERN Mangrove Portal. A major future benefit of providing these data is that the community has access to a historical and permanent record of mangrove states and dynamics, which can provide invaluable information on the impacts of human-induced and natural environmental change.
