Organization 



Due to the large number of 1:24,000 quadrangle sheets needed to cover the 

 Maine coast, the study area was divided into six regions along township lines 

 (figure 1). Maps within each region are numbered from west to east, beginning 

 with the northernmost quadrangle (figures 2 to 7). In cases where a map 

 contains more than one region, it has been grouped with the region in which 

 the greatest portion of the map lies. A list of quadrangles (and their 

 numbers) included in each region of the characterization area is presented in 

 table 1. All of the atlas maps for a region are placed together in one or 

 more file boxes. Within each box all maps of a single data type (i.e., Fish 

 and Wildlife) are placed together and ordered according to quadrangle numbers. 



The following section describes the data types contained in each of the four 

 map categories and presents the source of information for each category. 

 Narrative descriptions of certain data have been excerpted from the Maine 

 State Planning Office, Coastal Inventory (1977). 



ATLAS MAP 1: NATIONAL WETLANDS INVENTORY 



The U.S. Fish and Wildlife Service is currently conducting a National Wetlands 

 Inventory. The procedures and methods are described in the enclosed 

 publication, Classification of Wetlands and Deepwater Habitats of the United 

 States. Concepts and terms are defined and the hierarchical structure and use 

 of the classification system are explained in detail. In addition, chapters 4 

 to 8 of volume 2 of the characterization describe the occurrence of the 

 wetland types identified by the National Wetlands Inventory in the 

 characterization area. The symbology involved in identifying the wetland 

 types as they appear on the maps is presented in the map legend and explained 

 in detail in the enclosed report. 



Although the National Wetlands Inventory has not been completed Statewide, 

 most of the Maine coast has been inventoried and wetland types have been 

 mapped on quadrangles at the 1:24,000 or 1:62,500 and 1:100,000 scales. All 

 NWI data appearing in the Characterization Atlas are either direct 

 duplications of the 1:24,000 NWI maps or enlargements of 1:62,500 NWI maps 

 registered and reproduced with base maps. Data on the extent of wetland 

 acreage in each town of coatal Maine are included in appendix A of chapter 2. 



ATLAS MAP 2: LAND COVER 



The Land Cover information presented in Atlas Map 2 was supplied by the Maine 

 State Planning Office Coastal Inventory (1977). It is a photo-enlargement of 

 the Coastal Inventory Land Cover Type 1:48,000 overlays to the scale used in 

 the characterization atlas, 1:24,000. The minimum mapping unit is 5 acres (2 

 ha), with the exception of the townships of Gouldsboro, Sullivan, Sorrento, 

 T7SD, T9SD, and TIOSD. These six townships are mapped with a minimum unit of 

 20 acres (8 ha). The following explanation and description of the land cover 

 categories appears in the Maine State Planning Office, Coastal Inventory 

 Handbook (1977).
