Abstract
A mangrove forest at Wellington Point (south-east Queensland) was sampled between February and September 1978 for information on distribution and abundance of gastropod molluscs. Thirty species of gastropod were collected. The mangal could be divided into zones determined by floral species. Greatest variety of gastropods was recorded from the central Avicennia swamp and seaward edge zones. Variety declined in the Rhizophora and upshore zones. The highest population recorded was for juvenile Salinator fragilis (3,000 individuals per m2) on the Suaeda salt flat.
