Florida; saltgrass, tufted hair grass, and pickleweed in the Pacific 

 Northwest, and pickleweed, saltgrass, Jaumea, saltbush, and gum plant 

 along the south Pacific coast. 



Marsh plants are propagated by seeds and vegetatively. Seeding 

 is the most economical method, but must be confined to protected sites. 

 Most planting is with vegetative propagules such as sprigs dug from the 

 wild or from nurseries, seedlings grown in peat pots, or plugs taken 

 from the wild. 



Seeds are broadcast at low tide and covered by cultivation. Vege- 

 tative propagules are inserted by hand or by machine in holes or furrows 

 at low tide. Labor requirements for vegetative planting, including 

 plant acquisition, are from less than 100 to more than 1,000 man-hours 

 per hectare, depending primarily on species, propagule, spacing, and 

 degree of mechanization. Seeding requires only 20 to 50 man-hours per 

 hectare. 



Fertilizers are frequently valuable in speeding establishment of 

 new plantings on sandy soils, and are occasionally useful elsewhere. 

 Plantings may require protection from birds and animals and may be 

 damaged by drifting debris. 



Newly established marsh plantings require time to develop into 

 mature salt marshes. Full cover and near-maximum primary productivity 

 may be attained in 2 to 3 years . 



A tabular summary of regional plant adaptation is presented in 

 Table 1; a planting summary by regions in Table 2.
