This data set represents point locations for all of Oregon's seabird colonies with associated attribute information. The attribute information includes counts of nests and birds, where available, and estimates of the number of breeding birds for each species at a colony. Specific information regarding date, observers, type of survey, quality of the estimate, and source of the data are also provided for each record. The primary source for this data is:

Nearshore Ecological Data Atlas Planning Grid populated with the results of Marxan analyses for the Seabirdl target group. A series of Marxan scenarios comprised of 100 runs, with 10,000,000 iterations each, were completed. A best iteration was selected from each run, and a "Sum" solution resulted, which depicts how often within the 100 runs a planning grid cell was in a best iteration.

These data identify polygon locations where final critical habitat for the Western Snowy Plover is designated.

These data are intended to be used as a guide to identify the general areas where final critical habitat for the Western Snowy Plover is designated. The official legal descriptions of critical habitat are available in the Federal Register, 70 FR 56970
