Aleutian Islands - Potential Places of Refuge

This webpage was used to assist the workgroup in the development of a document describing Potential Places of Refuge (PPOR) in the Aleutian Islands Geographic Zone. The initial project was completed in September of 2007 and in 2014 was updated and strengthened as a result of recommendations included in the findings from the Aleutian Islands Risk Assessment

The objective of this project has been to identify docking, anchoring, mooring and grounding locations that may be selected as Potential Places of Refuge in order to enhance the overall response process.

Site Selection Documents

The risk layers map depicts some of the risk factors the workgroup used in selecting potential places of refuge. The workgroup identified candidate sites for potential places of refuge. These sites were researched and the resources and attributes of each were placed in a site assessment matrix and key.

Invasive Species Considerations

Alien or invasive species include seeds, eggs, spores, or other biological material capable of propagating that species that is not native to an ecosystem. Invasive species commonly are transported in ballast waters and cargo associated oil transport and shipping. During operations any species that are encountered that are suspected to be non-native should be collected and presented to wildlife managers. Additional information on invasive species can be found in the “Useful Websites” section below.
