U.S. Fish and Wildlife Service Proposes a Recovery Plan for 44 Endangered Hawaiian Species within Maui Nui

The proposed draft recovery plan will seek public comment on partnership-driven efforts to prevent extinctions and put species on a path to recovery

By Jordan Akiyama, Public Affairs Specialist, U.S. Fish and Wildlife Service

The U.S. Fish and Wildlife Service has published a draft recovery plan for 44 endangered species that either occur or have occurred on the Hawaiian Islands of Molokaʻi, Lānaʻi, Kahoʻolawe, and Maui, collectively known as Maui Nui. Recovery plans are roadmaps for the Service and partners to prevent extinction of species and support recovery. This plan covers 40 plants, three tree snails, and one yellow-faced bee. Hawaiʻi is home to 578 species protected under the Endangered Species Act, with many found nowhere else in the world.

The 44 species covered in the draft recovery plan are listed as endangered under the ESA and are currently at risk of extinction. The ESA defines threatened as species at risk of extinction in the foreseeable future. All the species in the draft recovery plan face similar threats — habitat loss, introduced disease and non-native and invasive predators like rats, cats, and pigs. In addition, climate change is exacerbating and accelerating these threats across the Hawaiʻi and the Pacific Islands.

“Recovery plans are an important step towards the rehabilitation of a species,” said Earl Campbell, Pacific Island Fish and Wildlife Office field supervisor. “Hawaiʻi is unique because many of the native and endemic species evolved for centuries in isolation, free from threats. Conservation strategies include addressing threats of invasive species, disease, and habitat loss that are being amplified by effects of climate change. These challenges showcase how important it is to continue working with our conservation partners, as we strive to preserve our native and endemic species for future generations.”

Plants are foundational to the unique ecosystems of the Hawaiian Islands, with many plants co-evolving in isolation with the archipelago’s endemic wildlife. The 40 plants addressed in the recovery plan face varying degrees of habitat loss and decline. Introduced ungulates, like deer and other hooved mammals, are destructive to the native vegetation in all the occupied or suitable habitats of the 40 plant species as they create trails that damage native vegetation cover, destabilize substrates causing erosion, injure roots and seedlings through trampling, create gullies that contribute to flooding, and promote invasion of nonnative species through transportation of seeds.

Invasive plant species, threats of fire and drought, disease, and predation from rodents and insects are also factors that threaten the 40 plants. Introduced ants interfere with pollinators such as yellow-faced bees by consuming large quantities of nectar without pollinating the plant. Diseases like rapid ʻōhiʻa death is an ongoing threat to ʻōhiʻa lehua, an important canopy tree in forest habitats that are home to endangered plants and animals. Rapid ʻōhiʻa death, associated with fungal pathogens (Ceratosystis spp.), kills individual trees as well as groups of trees. The disease is present on Maui and poses a significant threat to ʻōhiʻa on Lānaʻi and Molokaʻi if it were to become established on those islands. Other disease threats include myrtle rust (Austropuccinia psidii) and powdery mildew (Neoerysiphe galeopsidis). The latter which affects plant species in the genus Phyllostegia.

The ESA has been extraordinarily effective in preventing extinctions, with more than 99 percent of all listed species still with us today. The ESA has also spurred unprecedented partnerships on behalf of wildlife conservation in America, with diverse states, federal agencies, private landowners and stakeholders coming together to conserve and recover listed species and their habitats. In total, 54 species have been delisted and 56 downlisted due to recovery since the ESA was passed into law in 1973. Recovery plans are an important tool in achieving recovery and preventing extinction.

The draft plan will be available for public comment for 90 days. An electronic copy of the draft recovery plan is available at our website: https://ecos.fws.gov/docs/recovery_plan/Maui_Nui_Draft_RP_20211217_Signed.pdf.
