Data were tabulated and compared by calendar year. Because 

 only 6 months of data were collected in 1971 and only 10 months in 1977, 

 data for those years were not directly utilized in multi-annual data 

 compilations. 



Fifteen of the most abundant and representative species were 

 selected for in-depth analysis (Table 12-1) . These were the consistently 

 more abundant species from each of the three groups under consideration 

 (waterfowl, shorebirds and gulls) as well as two additional species, the 

 horned grebe (Podiceps auritus) and common tern {Sterna hirundo) . The 

 data from these species have been used in the discussion of trends and 

 relative abundance. 



For purposes of collecting and interpreting the data, the 

 harbor was divided into five areas (Figure 12-1) designated as follows: 



1. East Shore ; Coast Guard station to Lighthouse Point and 

 extending out into the shipping channel. 



2. Harbor Station Area : Tomlinson Bridge to the Coast Guard 

 Station and extending into the harbor to the shipping 

 channel and the West River channel. 



3. Long Wharf Area : From Tomlinson Bridge to City Point and 

 extending into the harbor to the shipping channel and the 

 West River channel. (This area adjoins both proposed 

 sewage treatment plant sites). 



4. West River Area : From a line from City Point to the tip 

 of Sandy Point up the West River to the 1-95 bridge 

 (beyond Kimberly Harbor) . 



5- Sandy Point and West Shore Area : Sandy Point and adjoin- 

 ing waters to the West River channel and the main ship- 

 ping channel, extending one-half mile along the shore to 

 the southwest of Sandy Point.
