Restoration Potential of Ruppia Maritima and Potamogeton Perfoliatus by Seed in the Mid-Chesapeake Bay
Abstract
This technical note outlines protocols for assessing the reproductive potential of Ruppia maritima and Potamogeton perfoliatus, two species of submerged aquatic plants that pre-dominate in the mesohaline reaches of the mid-Chesapeake Bay. Once reproductive potential by seed is defined for healthy populations of these species, their life cycles can be evaluated to identify nondestructive methods of harvesting seeds for restoration projects. Such non-destructive methods would leave intact the roots and rhizomes that persist in the aquatic soils and that are associated with population maintenance through vegetative spread. Data on reproductive potential would also allow managers to estimate the effects of herbivory. For example, in the Chesapeake Bay the non-native mute swan is a voracious feeder on submersed aquatic vegetation (SAV). Since expansion of SAV is a priority goal for all Bay restoration programs, a clear conflict exists between the presence of these swans and SAV restoration goals. Reproductive potential of the plants coupled with the consumptive data for swans would allow managers to calculate the swans' impact to plant reproduction.
