Waterfowl (Anatidae) Brood Data, Maine, 1977 – 1994

Our data include detailed information about 12 species of Anatidae broods encountered on four study areas in Maine during 1977–1994 as one dataset. The second dataset provides the characteristics of the wetlands which were monitored during the studies. The third dataset enumerates the effort (such as numbers of visits to each wetland) to determine numbers of broods and the number of young that reached Class IIC-III to fledge. Each wetland is described by size, pH, specific conductivity, and class according to the system of Cowardin and others (1979, Classification of wetlands and deepwater habitats of the United States, USFWS publication, 131 p.). More details of the datasets are included in the companion USGS Data Report.
