METADATA FOR LARGE AND COMPLEX WETLANDS OF RHODE ISLAND


A.  Identification and Description

1.	RIGIS-CAT-ID	
2.	DATA-SET-IDENT	lgwetlnd
3.	DISTRIB-NOTES	
4.	THEME-KEYWORDS	wetlands, habitat resources
5.	DATA-SET-DESC	Large and complex wetlands of Rhode Island.  Wetlands greater than 1 acre in 
size were considered for analysis.  Wetlands were ranked using criteria involving 
size, class diversity, surface water connections, surrounding habitat types, and 
proximity to other wetlands.  This calculation is fairly complex and is explained 
further on the Habitat Resources map produced by the RI Resource Protection 
Project.  Wetlands with a total rank greater than 14 were considered to be `large 
and complex wetlands'.  This data is for planning purposes only; it has no legal 
significance for any regulatory purposes and has not been adopted by RIDEM.  
The development of all wetlands, regardless of size is regulated by state and 
federal agencies.
