The Buoy-Deployed Seeding System BuDS Figure 1 was developed to take advantage of the natural ability of mature reproductive shoots of eelgrass Zostera marina to release seeds over a period of weeks, and offers a low-cost alternative method of planting eelgrass using seed that can replace or compliment broadcast seeding efforts Pickerell et al. 2005. This system may offer several advantages over current seeding methods including 1 it may more closely mimic the natural process of seed release with regard to timing and distribution 2 seed dispersal is targeted to preferred habitats where seedling development can be easily monitored, 3 equipment is inexpensive and can be reused, 4 the infrastructure i.e., storage facilities and staff for reproductive shoot and seed storage is not required and 5 it can employ nontechnical personnel, allowing for community-based participation in restoration activities. Although this system was initially developed for use with eelgrass, it is being adapted for use in the restoration of other species of submerged aquatic vegetation SAV within the Chesapeake Bay region.
