98 • Wetlands: Their Use and Regulation 



Regional Case Studies 



Ten OTA regional case studies (table 17) of 

 trends in wedand use in 21 States provided infor- 

 mation from three major sources: 



• Wetland inventory and trend information 

 (other than NWTS); There are few reliable 

 trend studies. Moreover, there are many prob- 

 lems with comparing inventory studies to es- 

 tablish trends, owing to variations in wetland 

 definitions, size categories, and study areas. 

 For example, in Minnesota, a 1950 inventory 

 examined wedands within 15,803 square miles 

 (mi^) of the prairie-pothole region. A 1955 in- 



ventory looked at Circular 39 types 1-8 in 

 western Minnesota; in 1964, types 3-5 were 

 inventoried in 19 western Minnesota counties; 

 and in 1982, types 3-5 (over 10 ^cres) were 

 inventoried in 1 4 western Minnesota counties 



Permit information on section 404 and State 

 programs: There are few cases where data 

 have been compiled for particular permit pro- 

 grams. Data that are available generally report 

 only what has been allowed under the reported 

 permit program and exclude information on 

 illegal activity and activities taking place in 

 wedands that au-en't covered by the permit pro-
