“…In recent times, increasing human activities such as dredging, water heating and sewage and waste disposal, in addition to natural disasters have impaired, reduced and decimated established seagrasses in shallow coastal environments (Phillips 1974(Phillips , 1980a(Phillips , b, 1982Fonseca et al 1979Fonseca et al , 1982aFonseca et al , b, 1984Larkum and West 1990). It is estimated that with in last two decades over 18% or 33,000 km 2 of seagrasses of the world were lost by indirect human impacts (Walker et al 2006).…”

Survival and growth of transplants of laboratory raised axenic seedlings of Enhalus acoroides (L.f.) Royle and field-collected plants of Syringodium isoetifolium (Aschers.) Dandy, Thalassia hemprichii (Ehrenb.) Aschers. and Halodule pinifolia (Miki) den Hartog Abstract Experimental transplantation investigations, using laboratory raised axenic seedlings of Enhalus acoroides and natural populations of Syringodium isoetifolium, Thalassia hemprichii and Halodule pinifolia in the Gulf of Mannar Marine Biosphere Reserve, found that the denuded seagrass ecosystem of this Gulf can effectively be restored with plug and turfs methods of seagrass transplantation. Axenically developed E. acoroides, transplanted by the staples method, established by adapting to the prevailing environmental conditions. 0% seedlings "washed ashore" when the staples method was adopted using 'L' shaped bamboo sticks for transplanting E. acoroides and S. isoetifolium seedlings. This suggests that the seagrass transplantation using "L" shaped bamboo sticks, as staples will be technically feasible and ecofriendly for future seagrass transplantation programmes. Substratum type, duration of low tide exposure and environmental parameters like surface water temperature and turbidity are key parameters determining the success of the transplantation attempts.

“…Traditionally, Z. marina restoration efforts involved manually transplanting plants in the form of plugs, peat pots, sods, cores or bare root plants (turions) from donor beds to restoration locations (Phillips 1974, 1980; Boone & Hoeppel 1976; Robilliard & Porter 1976; Churchill et al 1978; Fonseca et al 1979, 1982 a , 1982 b , 1984, 1985, 1994, 1998; Davis & Short 1997; Orth et al 1999). Although these methods have been moderately successful, the primary limitation of their use in large‐scale restoration has been the labor‐intensive nature of plant collection and transplantation.…”

The Chesapeake Bay, like many other temperate estuaries, has exhibited dramatic declines in the abundance of submerged aquatic vegetation (SAV) during the later half of the twentieth century. Because of the functions SAV serve in maintaining a healthy estuarine ecosystem, SAV restoration has become an important component of Chesapeake Bay restoration. Specifically, recent water quality improvements in areas from which populations of Zostera marina (eelgrass) have been extirpated have suggested that Z. marina restoration could succeed. Early restoration efforts involved transplanting Z. marina plants from healthy source beds to restoration locations, but this was labor intensive, time consuming, expensive, and potentially detrimental to donor beds. This multi-year project investigated new techniques for large-scale Z. marina seed collection and processing and compared two seed dispersal methods to evaluate cost effectiveness. Tens of millions of mature Z. marina seeds were collected through snorkeling, SCUBA, or with a mechanical harvester. Seed storage conditions and processing techniques were manipulated in order to maximize seed yield. Seeds were dispersed using two methods: spring seed buoys and fall seed broadcasts. Our costs for planting 1 ha of bottom with Z. marina seeds ranged from $6,674 to $165,699 depending on seeding density and dispersal method used. The average cost per Z. marina seed was $0.17. Interannual variations in seed collection yield and seed viability after summer storage had great impact on final costs. Our results suggest that the use of seeds for large-scale Z. marina restoration offers a competitive advantage to more traditional transplanting methods.

“…This study showed t*hat seagrasses could be vegetatively propogated from fragments, but that unless fragments with active rhizomatic tips, or sprigs with well-developed short-shoots were selected, rhizomatic growth would be slow. In subsequent studies (Druel, 1973;Kelly e_t al., 1971;Phillips, 1974;Ranwell et al, 1974) transplantation techniques have been perfected so that seagrasses can be maintained under controlled conditions almost indefinitely. A giant flume has been constructed at the University of Virginia for that purpose and for other seagrass studies (Zieman, 1977).…”
