Abstract: Waterlogging and salinity are considered to be the two major factors affecting growth and plant distribution in salt marshes. But while the effects of salinity are well known, few studies have investigated the impact of the former on plant survival. The purpose of this laboratory experiment was to determine the effects of water level on growth and survival of the halophytes Salicornia europaea and Atriplex prostrata. Plants were grown in the laboratory at the following levels of inundation: 1) roots and shoots completely submerged (high water), 2) roots completely submerged (medium water), 3) water level at the bottom of the pot (low water). The high water treatment caused 100% mortality in both species within one week. Survival was high for both species when grown in the other treatments, but there was an indication of lower survival (70%) in the medium water treatment for A prostrata than in the low water treatment (90%) after three weeks submersion. There was no significant difference (P >0.05) in biomass production between medium and low water treatments in either species.
