Data collected during 1957-1989 on the Platte and North Platte rivers was analyzed to detect changes in the temporal and spacial distribution of staging sandhill cranes. The data indicate that a significant west-to-east shift in crane distribution has developed since the late 1960s. The most negative changes have occurred between Lexington and Kearney, Nebraska, where vegetation encroachment has been most pronounced. A significant increase in crane numbers between the Wood River and Highway 34 bridges is attributed to the result of vegetation scouring flows and active removal of woody vegetation.
