Interactions between C3 and C4 salt marsh plant species during four years of exposure to elevated atity occupied intermediate elevations. . growth may have been restricted by drought and salt stress at the higher elevations, while . growth at the lower elevations may be affected by the higher frequency of flooding. Elevated CO., may affect the species distribution in the salt marsh if it allows .
