Because we wanted to compare the marsh at lie Grande with other 

 marshes in the vicinity, we also visited the marsh in the estuary at 

 Kerlavos ca . 5 km from lie Grande (Fig. 2). This marsh contained less 

 Juncus , no Spartina , and was dominated by Puccinellia maritima, 

 Armeria maritima (Mill.) Willd. , and Triglochin maritima along with 

 Plantago maritima L. , Cochleria officinalis L. , Halimione portulacoides 

 and Aster tripolium L. There was evidence of marsh removal by cleanup 

 operations in the Kerlavos marsh also, but it appeared that the marsh 

 was much less heavily impacted than that at lie Grande. We chose to 

 use this marsh area as a supplemental study site.

PROCEDURE 



Substrate 



Substrate samples were taken at the transplant source sites for 

 each species and also at the experimental planting sites each year. 

 These samples were analyzed for elemental concentrations, pH, organic 

 matter, and volume weight by the North Carolina Department of 

 Agriculture Soil Testing Division using their routine methods.
