This dataset includes a polygon vector shapefile illustrating the location of rapid survey plots surveyed in the Arctic Refuge 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.
These data do not represent all locations within the Arctic 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.
Potential users of these data should first contact the data authors listed below, as potential biases may occur within the data depending on the intended use. Therefore, potential users should contact the data authors to discuss intended use and how these data may or may not be applicable.
