Table 6. Nutria harvest data (1975-76 through 1986-S7) by semi-impoundment for Little Pecan 

 Wildlife Management Area. 



several of the semi-impoundments were mixed marsh types, these semi-impoundments were 

 categorized as follows: 



(1) Semi-impoundments 1,2,5,6,7, and 8 were considered to be brackish because of the 

 dominance of wiregrass and the absence of bulltongue (Sagitarria sp.). 



(2) Semi-impoundments 3 and 4 were considered to be intermediate because of the dominance 

 of wiregrass and bulltongue and the absence of maidencane {Panicwn hemitomon). 



(3) Semi-impoundment 9 was considered fresh despite the dominance of wiregrass and 

 bulltongue. 



Fur management focused on nutria {Myocastor coypus) since it was the most abundant furbearer 

 on LPWMA. Nutria harvest data from 1977-78 through 1985-86 averaged 1/2.1 ha in brackish 

 semi-impoundments, 1/1.2 ha in the intermediate semi-impoundments, and 1/3.2 ha in fresh semi- 

 impoundments. In the Chenier Plain of southwest Louisiana from 1970-71 to 1980-81, Linscombe 

 and Kinler (1985) found that one nutria was harvested per 3.0 ha of brackish marsh, 2.3 ha of 

 intermediate marsh, and 1.4 ha of fresh marsh. This suggests fur harvests from brackish and 

 intermediate semi-impoundments on LPWMA were greater than the respective Chenier Plain 

 average. In the fresh marsh, the average fur harvest was greater than in the fresh marsh semi- 

 impoundment on LPWMA. 



Better harvests in the brackish and intermediate semi-impoundments may be attributed to the 

 following factors:
