Seabird nesting concentrations comprise a conservation target based on geospatial concentrations of species with special threats and management needs.
Hawaiian Seabird Nesting Concentrations
Distribution of Nesting Concentrations
Seabird nesting concentrations are distributed among the main islands, but are not currently well developed on the islands of Hawai`i, Lāna`i, Kaho`olawe, and Ni`ihau. Most nesting sites occur in areas not dominated by native vegetation, often these are rugged cliffy areas, relatively remote points, or offshore islets. The main factors seem to be areas relatively free from predation by mammals, and relatively undisturbed by human traffic. Thus the seabird nesting conservation areas typically lie outside of all native ecological systems, with the exception of some coastal vegetation areas.
We selected for the ecoregion portfolio so that all of the most viable examples are represented for each of the islands. The islands bearing portfolio seabird nesting concentrations are listed here, and maps of the concentrations are affered below.
