Hawaiian Monk Seal Translocation Project Improves Survival

August 31, 2020 — The following was released by NOAA Fisheries:

In a recent study, we found that our Hawaiian Monk Seal Research Program’s translocation efforts from 2012 to 2014 proved highly successful. Translocation is “the deliberate movement of organisms from one site for release in another.” It has been broadly applied to manage and conserve terrestrial wildlife since the 1800s. But it is far less common in the marine world, and is rarely applied to marine mammals. However, our team’s efforts buck that trend—about 400 monk seals have been translocated since the 1980s.

Most of these actions were taken to reduce immediate risks associated with the seals’ location:

Monk Seal Recovery Efforts

These translocations are part of many activities our researchers and staff conduct to improve the survival of seals:

  • Removing marine debris from entangled seals and from their habitat
  • Removing fishing hooks embedded in seals’ bodies
  • Re-uniting mothers and pups who become separated
  • Mitigating shark predation
  • Rehabilitating injured, sick or starving seals
  • Vaccinating seals to prevent disease (distemper) outbreaks
  • Conservation translocation

We estimate that up to one-third of the remaining monk seals are alive due to these and other interventions.

Hawaiian Monk Seal Population Saw Signs of Recovery in 2019

March 19, 2020 — The following was released by NOAA Fisheries:

The Hawaiian monk seal population has shown some signs of recovery over recent years. The size of the monk seal population in 2019 was about the same as in 2018, with slightly more than 1,400 seals. Most of the population (about 1,100 seals) reside in the remote Northwestern Hawaiian Islands. Just about 300 seals call the main Hawaiian Islands home. While the population size hasn’t really changed since last year, the population trend remains positive in recent years. It has been growing at an average annual rate of 2 percent since 2013.  The potential for our continued conservation efforts to make such a positive impact is part of what makes Hawaiian monk seals one of NOAA’s Species in the Spotlight.

NOAA’s Hawaiian Monk Seal Research Program closely tracks these year-to-year population trends, thanks to a robust, long-term dataset. During the 2019 field season, dedicated field biologists lived and worked on remote islands in the Northwestern Hawaiian Islands for 3 to 5 months (depending on the site). In the main Hawaiian Islands, we rely on volunteers, members of the public, and agency partners who contribute to citizen-based seal monitoring.

NOAA concerned with parasite that kills monk seals that’s spread by cat feces

February 21, 2020 — Toxoplasmosis, a parasite found in cat-feces is threatening the survival of Hawaiian Monk Seals. It’s deadly and it works quickly. According to scientists with the National Oceanic Atmospheric Administration, it can kill within 48 hours. It’s listed as one of the top three threats against the endangered species.

Dating back to the 90’s, NOAA reports at least 12 seals have died because of Toxoplasmosis. There’s no exact count because not every corpse has been recovered.

“That doesn’t sound like a very high number but when there’s only 250 to 300 animals in the population that are being impacted by this, it’s significant,” Charles Littnan, Protected Species Division Director, NOAA Pacific Islands Fisheries Science Center, said.

It spreads when cat feces are washed into the ocean, contaminating the water. One seal was killed last month. Another, Pohaku, is recovering after a bystander spotted her logging or floating in the water.

NOAA teams departing for expedition to Papahanaumokuakea Marine National Monument

May 15, 2019 — It’s time again for a team of researchers to head out to the Northwestern Hawaiian Islands at Papahanaumokuakea Marine National Monument, where they will set up camps for the next five months.

The National Oceanic and Atmospheric Administration’s Ship Oscar Elton Sette departs on Wednesday for Papahanaumokuakea, one of the largest, protected marine conservation areas in the world and home to endangered Hawaiian monk seals, threatened green turtles and millions of seabirds.

NOAA researchers this year will conduct the usual tasks — measuring and tagging all weaned Hawaiian monk seal pups, conducting beach counts and removing marine debris. A team of biologists will also measure and tag basking and nesting sea turtles and monitor nesting activities at French Frigate Shoals.

Another field team, however, will focus on researching how animals responded to the loss of East Island at French Frigate Shoals, where a majority of Hawaii’s green sea turtles nest, and dozens of Hawaiian monk seals pup. East Island was washed away by Hurricane Walaka in October 2018.

Field researchers from NOAA, along with six partner organizations, will focus their research and conservation activities at French Frigate Shoals as well as Laysan Island, Lisianski Island, Pearl and Hermes Reef and Kure Atoll. They will also take day trips to survey Niihau, Nihoa, and Mokumanamana islands and Midway Atoll.

The NOAA Ship Oscar Elton Sette will transport state Department of Land and Natural Resources staff and supplies to Kure Atoll. At Lisianski Island, the U.S. Fish and Wildlife Service will help the NOAA team find routes through the dense vegetation that blocks the shoreline and access to monk seals.
