This report discusses transplanting methods, planting stock, planting 

 areas, planting times, and planting methods for seeds.

 Vol. 11, No. 3, July 1947, p. 279. 



Methods of harvesting eelgrass (Zostera marina) seed are discussed. Fruit- 

 ing stems of Zostera, with spathes containing seeds, are pulled up in 

 August. These are placed in a box which is then anchored to the bottom of a 

 salt creek, allowing the spathes to decompose and release the seed. Seeds can 

 be stored during the winter between layers of sand in a box anchored to the 

 bottom of a salt creek.

 Ecological Studies, Chesapeake Biological Laboratory Reference No. 446,

 1970, pp. 106-155. 



Submerged plants are important to the marine environment because of their 

 soil binding roots and foliage which provides food and shelter for marine 

 fauna. In the Chincoteague Bay area, Zostera marina (eelgrass) and Ruppia 

 maritima (widgeongrass) are the dominant submerged aquatic species. A 2-year 

 study was conducted on the distribution and primary production of these 

 species. Recommendations are also given for future dredging operations.

This article provides a summary of the taxonomy, distribution, abundance, 

 and biology of submerged vascular plants in the Chesapeake Bay and its 

 tributaries.

 grasses: Thalassia," Proceedings of the Fourth Annual Conference on the 

 Restoration of Coastal Vegetation in Florida, Hillsborough Community 

 College Environmental Study Center, Tampa, Fla., May 1977, pp. 70-75. 



Costs of planting Thalassia seeds were determined for nursery and field 

 planting operations. Planting is the most expensive field operation, at $0.31 

 per seed (1976 cost). Field collecting cost is $0.11 per seed, and nursery 

 planting cost is $0.06 per seed. The planting phase accounts for two-thirds 

 of direct costs of Thalassia bed creation.
