(b) Elevation . Needle rush grows over a range of eleva- 

 tions upward from about MHW which is probably controlled to some degree 

 by salinity and nature of tidal regime. There may also be different 

 populations of this plant that have developed in different regions 

 similar to those of smooth cordgrass (Seneca, 1974). 



(5) Sedge . This plant is a major component of salt, brackish, 

 and fresh water marshes in the Pacific Northwest. It has been planted 

 successfully and appears to be one of the best prospects for marsh 

 planting in this region. 



(a) Planting Method . Although sedge has been planted 

 only by hand it would work well in present planting machines. 



(b) Elevation . This species can be planted from about 

 MTL or a little below to above MHHW but grows best in midrange. Plant- 

 ing elevation should be partly determined by other species to be planted. 



(c) Density . Experience is inadequate to establish 

 planting density. Based on general growth habit, a spacing of 0.5 to 

 1.0 meter on centers appears practical for this species. 



(d) Planting Date . April through June appears to be the 

 preferred time for transplanting. 



(e) Management . Sedge was reported as very responsive 

 to fertilization on a sandy substrate in the lower Columbia River, with 

 little or no growth on unfertilized plots (Temyik, 1977). This plant 

 will probably respond to nitrogen and phosphorus under deficient condi- 

 tions in about the same way as smooth cordgrass. Tidal debris is 

 definitely a problem on many sites in this region, and care should be 

 taken to prevent smothering of new plantings where heavy deposition of 

 wood or litter occurs. 



(6) Tufted Hair Grass. Experience with planting this species 

 is limited, but it has been planted successfully. It is easy to trans- 

 plant and quick to establish. It is widely distributed in the Pacific 

 Northwest and available in large quantities in the wild (Temyik, 1977) . 



(a) Planting Method . Tufted hair grass has only been 

 planted by hand, 10 to 12 centimeters deep. Some planting machines 

 could be adapted to handle it. 



(b) Elevation . Natural range is from about MLHW upward, 

 but it can be planted successfully down to about MTL. When used with 

 sedge, the two species probably should overlap around or just above 

 MHHW. 



(c) Density . Plantings spaced from 0.5 to 1.0 meter on 

 centers are suggested.
