The Hawaiian Islands Humpback Whale National Marine Sanctuary is holding a public meeting to discuss its management plan.

Federal law requires the sanctuary to regularly review its management of the preserve.

It has already held a series of public meetings on every island in the main Hawaiian islands except for Niihau to get comments.

The sanctuary is asking anyone who wants to testify at Monday’s meeting in Honolulu to submit a written copy of their testimony 24 hours in advance.

The sanctuary lies in warm, shallow waters between Maui, Lanai and Molokai. It’s one of the world’s most important humpback whale habitats.

About two-thirds of the North Pacific humpback whale population migrates to Hawaii each winter to breed and calve.
