Re-establishment of native aquatic macrophytes may be used to enhance habitat for fish and other organisms, with additional positive effects on water quality. Species selection and planting depth for re-vegetation efforts may be of great importance due to lake-specific ecological factors that may affect survival. The objective of this research was to test whether water depth or species selection contributed to the overall survival of macrophytes planted inside protective exclosures. We planted three species along a water depth gradient (0.30, 0.60, and 1.0 m) - Stuckenia pectinata, Vallisneria americana, and Potamogeton nodosus. Our results indicated that the depth in which species were initially planted rarely had an effect on survival of P. nodosus or V. americana (p < 0.05), but species did have an effect (p < 0.05). Stuckenia pectinata did not survive during the experiment.
