Hawai‘i has been labeled the endangered species capital of the world. We have more endangered species per square mile than any other place on earth.
Of the extinctions that have been documented, 28 species of bird, 72 land snails, 74 insects and 97 plants have disappeared. (Hawaii Biodiversity)
The State, in partnership with a bunch of federal, university and private interests, conducts dozens of projects across the state to monitor, protect and enhance native and endangered species populations.
Statewide surveys to monitor population status and trend for water birds, sea birds and forest birds are conducted on all the main islands.
The surveys contribute to long term data to understand population changes and to provide early detections of any potential threats to population stability.
A project on Kauai has been developed to use modified marine radar to survey threatened and endangered seabirds that fly inland to nest at night.
The surveys are critical to a determination of the population status of these species that appear to have experienced a severe population decline.
Also notable was the discovery of what is perhaps the largest known breeding colony of the endangered Hawaiian Petrel on Lanai. This species was feared to have declined or been lost from Lanai until crews conducted extensive night surveys using radar.
Full-time field teams are now deployed to coordinate and conduct special projects for select species and habitats. These include the Kauai Endangered Seabird Project, the Kauai Forest Bird Recovery Team and the Maui Forest Bird Recovery Project.
These teams carry out management needs for native birds that include predator control, population monitoring, assessment of threats, and reintroduction into new habitats to reestablish populations.
Keauhou Bird Conservation Center Discovery Forest in Volcano, Hawai‘i Island has been saving critically endangered Hawaiian birds from extinction and restoring these species in the wild. Birds being cared for include the ‘Alalā, Palila, ‘Akeke‘e, and ‘Akikiki.
Likewise, there are other groups and agencies that support and participate in recovery activities, including DLNR, USGS, US Fish and Wildlife Service and others.
A field unit for the recovery of the ‘Alala, Hawaii’s most critically endangered species has been established. The ‘Alala Recovery Team is involved in an extensive community and landowner involvement program to lead the recovery of this species.
For many of Hawaii’s most critically endangered species, captive propagation and reintroduction is the only viable recovery strategy. Captive propagation programs are continuing for these species, which include five forest bird species and hundreds of plant species.
Notable long-term program successes include:
• Nēnē – (the State Bird) recovered from a population on the brink of extinction with fewer than 50 birds to an estimated 3,862 (2022 annual survey)
• ‘Alala – saved from extinction with a captive flock that has grown to over 115
• Puaiohi – recovering from a population numbering only a few dozen to approximately 494 (found only on Kauai)
• Palila – a new population has been established on the north slope of Mauna Kea (I recall the excitement and flurry of e-mails going around announcing a new nest with eggs on the north slope when I was at DLNR)
To date, hundreds of birds have been reintroduced into native habitats statewide. In addition, an extensive cooperative partnership continues a program for propagation and outplanting of native plants, maintaining hundreds of species, and outplanting thousands of plants into the wild.
There are a lot of people across the state (as well as support from the mainland) that are doing waaay cool stuff to help with the recovery of Hawai‘i’s native bird populations. We owe each our gratitude for their commitment and hard work. Thank you to all.
