The Big Island of Hawaii is a unique and biodiverse place, with various endangered species that call it home. These species face multiple threats, from habitat loss and hunting to introducing non-native species and pollution. Protecting these species is crucial for maintaining the health of the island’s ecosystem and preserving its natural beauty. This article will explore eight examples of endangered species on the Big Island, including their habitats, threats, and conservation efforts.
What Is An Endangered Species Exactly?

An endangered species refers to a plant or animal at risk of becoming extinct if it does not receive protection. Various factors can contribute to a species becoming endangered, including habitat destruction, hunting, pollution, and climate change. It is essential to protect endangered species because they each play a significant role in maintaining the ecological balance in their respective ecosystems.
Additionally, many endangered species, such as their medicinal properties, have potential benefits to humans. Conservation efforts, such as captive breeding programs, habitat restoration, and reduced hunting pressure, can help save threatened species from extinction. Overall, endangered species are crucial to the health and vitality of the planet, and it is vital to take steps to protect them for future generations to enjoy.
Exploring The Big Island’s Endangered Species
It’s no secret that the Big Island of Hawaii is home to some of the world’s most unique and biodiverse species. Here are eight endangered species on the Big Island.
Hawaiian Monk Seal

The monk seal is a key part of the marine ecosystem in Hawaii, as they feed on various fish and invertebrates and help maintain a healthy ocean balance. The Hawaiian monk seal is one of the rarest seals in the world, with only about 1,400 individuals remaining. They are found in the waters around the Hawaiian Islands and are threatened by habitat loss, hunting, and accidental entanglement in fishing gear.
The National Oceanic and Atmospheric Administration (NOAA) has taken measures to safeguard the monk seal, including implementing fishing gear regulations and imposing restrictions on human activities in their habitats. They also work in conjunction with local communities to educate them about the significance of the monk seal and how to avoid inadvertently causing harm to the animals.
Hawaiian Hoary Bat

The Hawaiian hoary bat is the only native land mammal in Hawaii and is listed as endangered. They are found on the Big Island and other islands in Hawaii and are threatened by habitat loss, pesticides, and collisions with wind turbines. The hoary bat is a crucial pollinator and seed disperser in the Hawaiian ecosystem, helping to maintain the health and diversity of the island’s plant life.
Conservation efforts to protect the hoary bat include reducing the use of pesticides and mitigating the impact of wind turbines on bat populations. Furthermore, efforts are being made to safeguard and restore bat habitats, which includes using artificial roosts and preserving native tree species.
Hawaiian Hawk (‘Io)

The Hawaiian hawk, also known as the ‘Io, is a bird of prey found only in Hawaii and is listed as endangered. The ‘Io plays a key role in the Hawaiian ecosystem, controlling populations of rodents and other small animals. It is threatened by habitat loss, hunting, and poisoning from rat poison used to control invasive species.
To protect the ‘Io, conservation efforts have focused on protecting and restoring native forests and habitats, reducing the use of rodenticides, and educating local communities about the importance of the hawk in the ecosystem.
Blackburn’s Sphinx Moth

The Blackburn’s Sphinx Moth is a giant moth found only on the Big Island of Hawaii. It is listed as endangered due to habitat loss and the impact of non-native species on its habitat. The Blackburn’s Sphinx Moth plays a vital role in the island’s ecosystem as a pollinator of native plant species.
To protect the Blackburn’s Sphinx Moth, conservation efforts have focused on restoring native habitats and controlling populations of non-native species that threaten the moth’s survival. Additionally, steps are underway to monitor moth populations and educate local communities about protecting endangered species in Hawaii.
Hawaiian Petrel

The Hawaiian petrel is a seabird found only in Hawaii and is listed as endangered. Habitat loss, predation by non-native species, and light pollution from urban areas threaten it. The petrel is a key part of the oceanic ecosystem in Hawaii, feeding on fish and other small animals and helping to maintain the balance of the food chain.
To protect the Hawaiian petrel, conservation efforts have focused on reducing the impact of light pollution on the birds, protecting and restoring native habitats, and controlling the populations of non-native species that prey on the petrel.
Hawaiian Goose (Nene)

The Hawaiian goose, also known as the Nene, is the state bird of Hawaii and is found on the Big Island and other islands in Hawaii. It is listed as endangered due to habitat loss, hunting, and predation by introduced species such as mongoose and feral cats. The Nene plays an important role in the Hawaiian ecosystem, helping to spread the seeds of native plants and controlling populations of insects and other small animals.
Conservation efforts to safeguard the Nene include restoring natural habitats, safeguarding them against predators, and introducing captive breeding programs to reduce the chance of extinction.
Humpback Whale

Humpback whales play a crucial role in the oceanic ecosystem, helping maintain the food chain balance and regulating populations of fish and other small animals. While not exclusive to the Big Island, humpback whales are a key part of the island’s ecosystem and economy. They migrate to Hawaii from Alaska yearly to mate and give birth and are threatened by habitat loss, hunting, and entanglement in fishing gear.
To protect humpback whales, conservation efforts have focused on regulating fishing gear and reducing the impact of human activities on whale habitats. Additionally, steps are underway to educate local communities and tourists about the importance of humpback whales and how to avoid accidental animal harm.
Hawksbill Turtle

The hawksbill turtle is a sea turtle species found around the Hawaiian Islands and listed as critically endangered. Hawksbill turtles play an important role in the marine ecosystem, helping to maintain the balance of the food chain and supporting the health of coral reefs. They are threatened by habitat loss, hunting, and entanglement in fishing gear.
Conservation efforts aimed at safeguarding hawksbill turtles include regulating fishing equipment, preserving and rehabilitating their habitats, and raising awareness among local communities and tourists on the significance of these turtles and how to prevent any unintended harm.
Did You Know About These Endangered Species On Big Island?
In conclusion, the Big Island of Hawaii is home to a diverse range of endangered species, each playing a crucial role in maintaining the health and balance of the island’s ecosystems. Conservation efforts are underway to protect these species from a range of threats, including habitat loss, hunting, and the impact of human activities. Through education, regulation, and habitat restoration, you can help ensure these endangered species’ survival and preserve the Big Island’s natural beauty and diversity for generations to come.
