It is a small herbaceous plant that occurs in sea beds and other saltwater environments in the Indo-Pacific . Br.) Field and laboratory studies indicated that during years of average river discharge (1980, 1982), Halophila ovalis was little affected by the salinity range experienced (15–35‰). However, during 1981, a year of high discharge, conditions of low salinity and poor light supply caused severe declines in biomass, particularly in the Canning Estuary. These results were incorporated into a model to determine how much of the variance in productivity could be accounted for by these three factors, assuming independent action.
