Several pans in the high marshes sampled by aquatic sweep net were 

 inhabited by a variety of aquatic forms (Fig. 9). The immature high 

 pan had large numbers of copepods (mostly harpacticpods) , the amphipod, 

 A. aonfevvioolus , and oligochaetes. The mature high pans also contained 

 amphipods and oligochaetes; corixids, and ephydrid and culicid larvae 

 were also abundant. 



Infauna of tidal creeks in the sedge and mature high marshes were 

 similar (Fig. 10). Oligochaetes, polychaetes, and amphipods were the 

 most abundant forms in each creek. Capitellids and ampharetids 

 dominated the polychaete fauna in both creeks, although spirobids and 

 spionids were also abundant in the mature high creek. Amphipods were 

 mostly Corophiim and Anisogcormarus oonferviaolus ^ but included some 

 talitrids and Ampithoe in the mature high creek. Macoma halthioa, a 

 small tellinid bivalve, was common in the sedge creek but absent from 

 the mature high creek. 



Animals collected in the tidal creeks by aquatic sweep net were a 

 mixture of aquatic and terrestrial animals also collected in lare 

 closure samples and in creek infauna samples (Fig. H). Presumabl ^""
