ResumoPosidonia and other seagrass genera cover vast areas along the coast of temperate Western Australia, where it seems that disturbance and recolonisation are the dynamic forces which govern the pattern of seagrass beds. Some species of Posidonia may take 60–100 years to cover cleared substratum while species of other genera may come and go within a year. Three case studies of spatially widely separated seagrass beds are given. They illustrate that depth, weather and location make great differences to the extent and diversity of seagrasses. Comments on reproductive ability and observations on seedling growth and vegetative propagation are given with emphasis on the "Posidonia ostenfeldii" complex.
