Note: HP signifies P. hydropiper community at high level above the water table, HT denotes T. lutarioriparia community at high level above the water table, LP indicates P. hydropiper community at low level above the water table, LT refers to T. lutarioriparia community at low level above the water table, VT indicates vegetation type, and WL refers to water level. Different lowercase letters represent significant differences among groups (p < 0.05).
