This dataset includes a polygon vector shapefile illustrating the location of rapid and intensive survey plots surveyed on the Yukon Delta as part of the Program for Regional and International Shorebird Monitoring (PRISM). This dataset provides the geographical location of survey plots that can be linked to the data collected in the field via the PlotID field.
A portion of these data are available on ServCat (https://ecos.fws.gov/ServCat/Reference/Profile/57583).
Much of these data have been published in Lyons, J.E., S.C. Brown, S.T. Saalfeld, J.A. Johnson, B.A. Andres, K.M. Sowl, R.E. Gill, Jr., B.J. McCaffery, L.R. Kidd, M. McGarvey, B. Winn, H.R. Gates, D.A. Granfors, and R.B. Lanctot. In press. Global importance of the Yukon-Kuskokwim Delta, Alaska, to breeding shorebirds. Ornithological Applications.
These data do not represent all locations within the Yukon Delta National Wildlife Refuge where specific avian species may be present, as surveys only occurred in discrete survey plots. Additionally, individual birds may have went undetected within survey plots, as detectability was likely less than 100%, and is a function of many variables, including differences in species, habitat, time-of-year, weather conditions, survey effort, and individual surveyor. The data providers have invested considerable effort in QA/QC, but it is possible that undetected errors remain. It is strongly recommended that careful attention be paid to the contents of the metadata file associated with these data to evaluate data set limitations, restrictions or intended use. The originators of this dataset shall not be held liable for improper or incorrect use of the data described and/or contained herein.
