Trapping data could not be associated with the areas on which 
the transects were located because boundaries of trapping units 
changed somewhat from year to year. However, the transects were 
located in that part of southwestern Louisiana where numbers of 
nutria first settled and where large populations developed. By 
1953 in the western portion of Marsh Island, numerous trails could 
be seen from the air (verbal communication, John J. Lynch). During 
three trapping seasons, the following numbers of nutria were taken 
from Marsh Island: 
1953-54 10,042 
1954-55 13,578 
1955-56 14,833 
General observation of nutria activity in the region of 
Transect A indicated that the 1955-56 trapping removed a larger 
proportion of the nutria population than during the previous 
trapping season, and that nutria were less abundant during 1956 
than previously. 
No trapping was permitted on the Rainey Wildlife Sanctuary 
where Transect B was located. WNutria apparently had been numerous 
on the sanctuary, but along Transect B they appeared to be less 
abundant than on Transects A and C. 
Transect C was located on that portion of the lands of 
Louisiana Fur Corporation which produced the highest nutria catch.
