ACKNOWLEDGEMENTS 



Cooperation with our French colleagues (Madames Le 

 Campion-Alsumard, Plante-Cuny, and Vacelet from Marseille and Monsieur 

 Levasseur and Mademoiselle Jory from Rennes) has been invaluable. In 

 fact, our work would have just about been impossible without their 

 help- They have gone out of their way to help us while we were in 

 France, such as arranging a meeting with the Mayor of Pleumeur-Bodou, 

 making observations on our experimental plots during the interim of our 

 visits, and providing laboratory facilities for processing samples. 

 Presently we are cooperating with Monsieur Levasseur on nursery 

 production of transplants and monitoring of our plantings until 

 November 1982. He has also agreed to serve as the major professor for 

 a graduate student from the United States who is a candidate for a 

 Fulbright Scholarship. Among his tasks, this student would follow our 

 plantings and document the invasion of these plantings by other marsh 

 plants subsequent to our active involvement in the project. In 

 summary, the association with our French colleagues has been very 

 beneficial from our standpoint and we cannot overemphasize the vital 

 part they have played in making our research proceed smoothly. 



We thank Amoco Oil for providing the funds for our research 

 through NOAA Contract No. NA79RAC00018. We thank NOAA personnel 

 especially Drs . W.N. Hess and D.A. Wolfe for providing us the 

 opportunity to conduct this very timely and environmentally beneficial 

 research and for their cooperation throughout the period of the 

 project. 



Last, special thanks for technical assistance in field work and in 

 data analysis go to Messrs. C.L. Campbell and L.L. Hobbs who made the 

 overall research effort a success. 



SUMMARY 



Experimental plantings of Halimione portulacoides , Juncus 

 maritimus , Puccinellia maritima, Spartina maritima , and Triglochin 

 maritima have been made at lie Grande and Kerlavos, France in an 

 attempt to rehabilitate salt marsh that was impacted by the Amoco Cadiz 

 oil spill and subsequent cleanup operations. Over 61 experimental 

 plantings including over 11,000 transplants have been established to 

 test two types of transplants, conventional and slow release fertilizer 

 materials over a wide range of substrate and elevation conditions and 

 to develop nursery areas. Spartina transplants survived at lower 

 elevations than those of any other species tested, but the best growth 

 of transplants of all species tested occurred within + 0.3 m of the 

 elevation of the natural marsh in the vicinity. Survival and growth 

 data indicate that transplants of Puccinellia with a core of root and 

 substrate material intact (plugs) were superior to those transplants 

 with roots only (sprigs).
