Table 21. Habitat areas in hydrologic unit V, Terrebonne. 



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.
