The IUCN RedList considers Laysan Albatrosses to be “Close to Threatened”. Within the early twentieth century, people hunted albatrosses to close extinction for feathers to make hats. Then, within the past due twentieth century, the driftnet manner of industrial fishing led to any other steep decline within the getting better inhabitants. 

The majority of breeding Laysan Albatrosses in Hawaii may also be discovered on Halfway Atoll, Laysan Island, and French Frigate shoals.

These kind of colonies are on very low-lying land plenty with little human presence. Unfortunately, emerging sea ranges have resulted in tragic failures from flooding of the breeding grounds.  

Sea-level upward thrust is expected to extend and may spell the top of the Laysan Albatross. So, conservationists in Hawai’i’m hoping to maintain small, outlying Laysan Albatross colonies on upper floor. On Kauai and Oahu, sparse clifftop colonies and birds settling in human habitations are safe from flooding. Alternatively, invasive predators, maximum particularly rats, mongooses, and home canines, pose an excessively top possibility to nesting Albatrosses.
