Sandhill Crane Staging And Whooping Crane Migratory Stopover Dynamics In Response To River Management Activities On The Central Platte River, Nebraska, Usa, Felipe Chavez-Ramirez
Proceedings of the North American Crane Workshop
The Central Platte River Valley (CPRV) is a critical stopover for migrating whooping cranes (Grus americana) and the most important staging area for sandhill cranes (G. canadensis) in North America. Due to reduced water flows caused by human activities, the Platte River no longer follows its traditional hydrograph which consisted of high spring flows that produced scouring action that eliminated vegetation. To provide adequate crane roosting habitat during stopover and staging periods, annual and woody vegetation has been mechanically cleared on eastern portions of the CPRV since 1980. Staging sandhill crane riverine roosting area has decreased …
