Abstract

Virtually the entire Rocky Mountain population (RMP) of greater sandhill cranes uses the San Luis Valley (SLV) of Colorado as a spring stopover area. RMP cranes in the SLV depend on unharvested grain provided on Monte Vista National Wildlife Refuge, and on waste grain in privately owned fields. In recent years, however, fall tillage and irrigation of grain fields has become increasingly widespread in the SLV. These changes in farming practices have resulted in an unmeasured reduction in waste grain availability for RMP cranes during spring and have prompted concern over whether current or projected foods are adequate to meet spring demands of the target population size of 18,000-20,000 RMP cranesa?|
