The West Fisher also has good potential to support harlequin duck 

 production. The West Fisher ranks high in terms of providing habitat 

 components, emd has a combined gradient average of 1.0 %. Possible 

 limiting factors for supporting harlequin duck production on the 

 West Fisher may be stream flow volume, the presence of brood rearing 

 common mergansers, and timber harvest related disturbances. 



The following streams all have the potential to support harlequin 



duck production in one capacity or another. They are listed in a 



'loose' order according to this survey and the comparison of data
