Abstract

Air photographic records of the Tweed River Estuary were compiled for 1930, 1948, 1962, 1978, 1985, 1994. The distribution of mangrove and saltmarsh was mapped from all photographs for all areas common to all photographs. The survey revealed a substantial increase in the area of intertidal wetland, particularly mangrove, in the period 1930 – 1994. The increase in wetland area occurred throughout the estuary, including the Fluvial Channel, the Tidal Channel and the Broadwaters. Factors responsible for the changes are suggested.
