harlequin populations in Montana (currently in preparation) ; 



2) investigate site fidelity, inter-stream movement, reproduction 



and mortality to allow estimations and modeling of what 

 constitutes a viable harlequin population (began in 1992) ; 



3) determining the primary limiting factors for harlequin duck 



populations in occupied and historic habitat situations in 

 the Northern Rockies; 



4) developing standardized surveying protocols for occupied and 



potential harlequin streams; 



5) developing management guidelines for maintaining harlequin 



populations and habitat; and 



6) assess the impacts of past and current habitat modification 



and develop techniques to restore harlequin populations and 

 habitat.
