Protection of loons may ultimately depend on cleaning up pollution 
     
     sources, but more immediate problems can be alleviated. Artificial nest 
     
     structures have proven successful in reducing swamping of nests. In New 
     
     England, groups of cottagers have formed associations that actually 
     
    
   
   
    
     guard nests from disturbance, in some states backed up by heavy fines for 
     
     harming loons.

     STAGING AREA THREATENED 
     
    
   
   
    
     BY RICHARD YANK 
     
    
   
   
    
     Southern Quebec's most important staging area for Canada Geese is 
     
     currently threatened by a major agricultural project being proposed by 
     
     the province's Department of Agriculture, Food and Fisheries. 
     
    

    
     Lake St. Peter is a large freshwater basin formed by the widening 
     
     of the St.Lawrence River half-way between Montreal and Quebec City. Ex— 
     
     tensive marshes, approximately 10,000 ha. in area, line the shores of this 
     
     shallow lake and provide critical nesting habitat for an important pop— 
     
     ulation of waterfowl and other marsh-dwelling species. In addition, the 
     
     lake's 1,500-2,000 ha. floodplain attracts large numbers of migrating 
     
     waterfowl which stage there from early April to mid-May each year. Is— 
     
     lands at the western end of the lake support one of Quebec's most im- 
     
     portant heronries. 
     
    

    
     In late April, at the peak of spring migration, an estimated 70,000- 
     
     lO0,000 Canada Geese and 15,000 dabbling ducks can be observed along the 
     
     south shore of the lake. These birds represent, respectively, 50 and 3 % 
     
    

    
     of the migrant population found along the total length of the St. Law— 
     
     rence. 
     
    

    
     Current proposals involve a series of dikes along both shores of 
     
     the lake. Control gates would allow floodwater to enter. At some point 
     
     the gates would be closed and the accumulated water would be pumped back 
     
     into the lake. Thus the floodplain could be drained as soon as possible, 
     
     allowing earlier access to the fields for sowing crops and increasing the 
     
     length of the growing season. 
     
    

    
     While the proposed system is preferable to permanent drainage, it 
     
     is obvious that the management of such a system would be of critical im- 
     
     portance in determining the eventual impact on waterfowl. The impact on 
     
     the balance of this complex ecosystem could be much more severe.
