Table 12. Habitat areas in hydrologic unit IV, Barataria. 



Due to differences in classification and resolution 

 between the 1955 and 1978 maps, care must be taken 

 in interpreting the area changes shown in this 

 .table. See text for a more complete explanation. 

 Brackish marsh was not delineated on the 1955 maps, 

 but was included with salt marsh as "nonfresh 

 marsh." Therefore, the change in salt marsh number 

 was set equal to the change in total nonfresh marsh.
