Aerial photographs have been acquired over mangroves regions in Australia since prior to the 1940s and provide an important historical record of their extent and state, including broad species distributions and donations. From stereo aerial photography, canopy height models (CHMs) can be derived, including from early black and white photography (Lucas et al., 2002).
TERN aims to provide links to aerial photography holdings relevant to mangrove areas and access to products including:
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.

Photographs taken from aircraft that are or have the capacity to be georeferenced provide a valuable source of information that can inform the past states of mangroves and provide a record against which to assess future change. Hence, this section of the TERN Mangrove Portal provides the opportunity to view and download photographs of mangroves throughout Australia.
