【 摘 要 】

Water and emergent vegetation are key features influencing nest site selection and success for many marsh-nesting waterbirds.Wetland management practices such as grazing, burning, and water-level manipulations directly affect these features and can influence nest survival.We used model selection and before-after-control-impact approaches to evaluate the effects of water depth and four common land-management practices or treatments, i.e., summer grazing, fall grazing, fall burning, and idle (no active treatment) on nest survival of American coots (Fulica americana) nesting at Grays Lake, a large montane wetland in southeast Idaho.The best model included the variables year
