Waterfowl Production On A Spring-Fed Salt Marsh In Utah, Donald E. Mcknight

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Results of past studies on the spring-fed salt marshes of Utah indicated that waterfowl production on these areas was much lower than on Utah's river-fed marshes. Waterfowl production on the newly-established Fish Springs National Wildlife Refuge, a spring-fed marsh, increased considerably, however, after its waters were impounded. It was believed that by determining what caused this increased production at Fish Springs it would be possible to obtain greater waterfowl production at other spring-fed marshes. Consequently waterfowl populations and factors affecting waterfowl production on this marsh were studied during the summers of 1966, 1967, and 1968.

Populations of breeding ducks averaged …
