In one of our May 1979 experimental plantings of Puccinellia at Kerlavos (Figs. 56, 57, 58), 97% of the transplants in the 60 m^ area had been invaded by at least one other species by May 1981 (Fig. 59). Of these transplants which had been invaded, 66% were invaded by two or more other species. The most abundant invader was an annual species of Salicornia which was present in 94% of the transplants sampled. Other invading genera in the order of their percentage of presence per transplant sampled were Cochleria (49%), Halimione (24%), Spergularia (10%), and Armeria (1%). 413
