Seasonal Utilization of Sago Pondweed by Waterfowl at Bear River Migratory Bird Refuge, Utah
Abstract
Seasonal utilization of sago pondweed (Potamogeton peetinatus L.) by waterfowl was studied at Bear River Migratory Bird Refuge by comparing amounts of sago production on a series of plots on Unit Four. One plot was available to carp and waterfowl; one only to carp and one available to neither. Waterfowl utilization of sago in summer and spring was not significant however 52 percent of the tuber crop was used by waterfowl in fall.
