The relative ecological importance of each colony was assigned by OCMP, based on the following criteria, which were developed by seabird experts:• Importance level 1: Offshore colonies/complexes with ≥ 5,000 breeding birds, OR offshore or mainland colonies with Tufted Puffins, OR offshore colonies with Leach’s Storm Petrels or Fork-tailed Storm Petrels• Importance level 2: All rocks, reefs, and islands of Oregon Islands and Three Arch Rocks NWRs with breeding seabirds that were not included in Importance level 1, OR mainland seabird breeding sites with ≥ 1,000 breeding birds• Importance level 3: All other coloniesThe number of breeding birds used in the determination was based on the maximum observed count from 1979-2017.
