Salinity tolerance of inland halophytic vegetation of North America

Irwin A. Ungar

Open full text 9 citations

Abstract

SummaryThe distribution of inland halophytic species of North America is chiefly affected by two environmental factors, soil moisture and soil salinity which interact to determine the soil water potential. Seasonal changes in soil moisture and soil salinity have a marked effect on halophyte seedling establishment and this leads to a great decrease in the number of plants surviving to maturity on the salt pans. Zonation in these environments is controlled by plant species tolerance to salinity and their ability to compete with other species under more moderate conditions.
