Abstract

The artificial creation of wetlands has become a common means to mitigate the effects of wetland alteration due to development. The establishment of diverse, functional plant communities is a crucial and challenging part of a wetland creation project. This study analyzes plant community structure of a seven year old, artificially created wetland. One hundred and four vascular plant species are documented from the study site including two species listed as rare for New Hampshire and the first state record for an introduced weedy species. The computer program TWINSPAN used species abundance data to classify the vegetation into seven cover types. The three plant associations of the open water habitat were: Chara cover type, Potamogeton pusillus cover type, and the Potamogeton natans cover type. The four plant associations of the emergent habitat were: Eleocharis smallii cover type, Typha latifolia cover type, Juncus effusus-Phalaris arundinacea cover type, and a Carex stricta cover type. Each cover type and associated habitat was described and delineated.
