A new NOAA report on the Northwestern Hawaiian Islands (NWHI), protected by the Papahānaumokuākea Marine National Monument, provides the sharpest picture yet of the region's marine life and ecosystems.
Prepared by NOAA's National Center for Coastal Ocean Science, the report, A Marine Biogeographic Assessment of the Northwestern Hawaiian Islands, examines the geographic distribution of the island chain's marine life and habitats, and the conditions that determine where they are found.
"This report provides an important summary of the monument's marine ecosystems," said Randy Kosaki, NOAA's monument deputy superintendent and research coordinator. "The report reveals patterns and details about species in the Northwestern Hawaiian Islands, helping us better understand this special place."
Significant findings highlighted in the report:
"The ecosystems of the Papahānaumokuākea Marine National Monument are relatively pristine," said Alan Friedlander, a University of Hawaii/U.S. Geological Survey fisheries ecologist and contributor to the NOAA report. "The dominance of top predators that we see in the Northwestern Hawaiian Islands is rare and gives us new insight into how natural coral reef ecosystems should function."
Monument managers will use the report as a baseline to monitor changes in the NWHI, identify resource management and research priorities, and develop a Natural Resources Science Plan for conducting future studies in the NWHI. A draft of the monument's science plan will be available for public comment this summer.
NOAA prepared the report with input from the Papahānaumokuākea Marine National Monument co-trustee agencies, the University of Hawaii, the Hawaii Institute of Marine Biology, and the University of California, among others.
