Global Study Reveals Seabirds as Critical Connectors Between Islands, the Ocean, and People
A new study shows the power of seabirds to drive entire ecosystems by circulating nutrients between land and sea!
Hope is flourishing across our world’s ocean and the islands that rise from it. From the return of lost species to the revival of forests and reefs, the seeds of our efforts are taking root as communities, ecosystems, and species thrive once more.
Explore our 2025 Impact Report and the highlights of a year where restoration turned possibility into progress.
As we wrap up 2025, we are filled with gratitude for the incredible results we are seeing on islands around the world. With community-led conservation, holistic restoration, and partnerships as driving values, Island Conservation enabled dramatic recoveries. It is with great pride—and deep appreciation—that we share our 2025 Impact Report.
This year brought extraordinary breakthroughs. The Mares Leaf-toed Gecko, presumed extinct for 5000 years on Rábida Island in the Galápagos, was rediscovered thanks to our work there—proof that hope is never lost! In the Island Nation of Tuvalu, restoration work safeguarding biodiversity and building ecological resilience in one of the world’s most climate-threatened nations. And in the Republic of the Marshall Islands, thousands of birds are once again nesting and native seedlings are now anchoring coastlines and restoring life to fragile habitats. All of these victories benefit islands, oceans, and people around the world.

With innovative technologies, we are increasing the efficiency and effectiveness of our work. We started using drones and hyperspectral imaging to map remote terrains to document ecosystem health in vivid detail. And a new environmental DNA (eDNA) tool is enabling us to detect the species present on the island, sometimes within just an hour using a few liters of water or samples of soil. This exciting new tool can identify the presence of invasive species, or it can document the native biodiversity present over time as islands recover after our conservation interventions. And sophisticated AI-enabled cameras paired with drones have dramatically reduced staff time, efforts, and expense.
Island Conservation’s reach and ambition continues to grow—especially as we lead the charge to link healing islands to improving ocean health and coastal resilience. We are forging strategic alliances to elevate islands within global policy agendas, ensuring their unique challenges and contributions are recognized, addressed, and supported. Through the Island-Ocean Connection Challenge (IOCC), a volunteer collective that links land and sea conservation, we and our partners are demonstrating the multiple benefits of island restoration for nature, oceans, people, and climate resilience. And this is just the beginning. The International Union for the Conservation of Nature adopted our petition for a United Nations-sanctioned Decade of Island Resilience. Momentum is only growing.
Please take a moment to explore the full report and celebrate these milestones with us. Together, we will continue to advance Island Conservation’s mission of restoring islands for nature and people worldwide.

Islands hold an extraordinary share of life on Earth. Home to 900 million people, 20% of global biodiversity, 31% of all plant species, and 50% of all threatened species. 50% of all marine life depends on healthy islands, with these unique ecosystems acting as anchors for ocean health.
At the same time, islands are on the frontlines of the triple planetary crisis — biodiversity loss, failing ocean health, and climate change. Yet, they are also inherently resilient. As quickly as ecosystems can unravel, they can recover and rapidly transform to generate outsized benefits for nature and people. Restored island forests, for example, can lock away tens of millions of metric tons of carbon, strengthening the natural climate resilience that protects island communities and the planet.
By investing in island restoration, we’re addressing the crises of our time and advancing proven, scalable solutions for a thriving future.
Over the course of the year, our field staff spent thousands of hours and hiked hundreds of miles. They camped along the coast, on boats, at the summit of a number of islands, and made makeshift campsites in the rain with tarps. They collected thousands of hours of camera trap and acoustic recording data, conducted seabird counts, took hundreds of soil and plant samples to show increase in nutrients after seabird colonies are restored, and observed wildlife across wide ranges of habitats on land and by boat. We even had one staff member claim they hiked 1,000 miles scouting for Tongan Petrels (and said there was no need to fact check).

Over 100 years later, 2 locally extinct species are back from the brink and have returned home for the first time. Galápagos Rails return to Floreana Island in the Galápagos archipelago after 190 years and Polynesian Storm-petrels return to Kamaka Island in French Polynesia after a century.
Plus, the Mares Leaf-toed Gecko which was thought to be extinct for over 5,000 years (yes, 5 millennia) returns!

By removing invasive species that threaten locally important crops and natural resources we have begun to directly benefit local farmers and landowners in the Cook Islands, Tonga, Tuvalu, and Samoa.
These interventions lay the foundation for improved food security and could indirectly benefit thousands of island residents in the future.

We initiated large-scale climate resilience monitoring across 50 islands, leveraging NASA satellite data from 1984 to present. This effort tracks long-term changes in vegetation structure and health to demonstrate how island restoration strengthens natural defenses that enhance the resilience of biodiversity and island communities.
Field data collected in Samoa, Tonga, Wallis and Futuna, and the Dominican Republic is documenting the potential for tropical forest regeneration to better withstand cyclones, drought, and warming.

We processed over 70,000 hours of acoustic recordings — a dataset so vast it would take nearly a decade to listen to it all — across 6 islands, identifying 74 species calls with our partners at Conservation Metrics. By training their algorithm and machine learning tool to recognize specific species calls, we can quickly process large volumes of data that would take years to review manually.
This helped document the presence of 7 species for the first time and monitor nocturnal species on Late Island and Tofua Island in Tonga.

Plus, we published 5 innovation papers to influence the sector to do the same.
Innovative technology is transforming efficiency, and we are paving the path forward. A new eDNA tool can detect invasive rodents within an hour. Drones enabled restoration on six islands previously unattainable due to terrain and other variables.
And AI-enabled cameras paired with drones are reducing operational costs by 400%, meaning donor dollars stretch farther than ever.

In just one year, we saw an amazing transformation. In 2024, we saw a dying forest on Jemo Islet and Sooty Terns were absent from Bikar Atoll where a colony of over 27,000 was recorded in the 1960’s. In 2025, thousands of Pisonia grandis seedlings were sprouting from the newly regenerated forest, and 2,000 Sooty Terns were feeding hundreds of chicks.

For the first time in decades, Galápagos Rails have returned to their native island habitat on Floreana Island in the Galápagos archipelago. This is a major sign of renewed ecological balance as these are one of the first locally-extinct species to reappear along with the Cactus Finch which was reintroduced in 2024.
Islands are home to half of our world’s biodiversity but face a disproportionate share of global extinctions. The swift return of the Galápagos Rail demonstrates that when we restore islands, we give some of the planet’s most vital ecosystems and at-risk species a chance to recover. In many cases, these rebounds happen astonishingly fast, showing just how quickly nature can respond when given the opportunity.
Every household on Robinson Crusoe Island in the Juan Fernández Archipelago participated in a community project funded by Fondation Franklinia to add 4,000 native plants inside 54 protected areas across five forests.
3,331 trees, 292 shrubs, and 287 ferns were added, protecting 17 IUCN-threatened species. 26 community members were trained to safeguard the new plants and seedlings, with nurseries expanded on two islands and biosecurity systems implemented.

After years of development, we’ve onboarded our first new drone vendor, introducing a completely new platform and company to the conservation technology landscape. This milestone represents more than operational efficiency: it’s about breaking down barriers to access by ensuring these critical tools are commercially available for any organization to purchase.
By catalyzing a competitive marketplace with multiple service providers, we’re making advanced conservation technology accessible to practitioners everywhere. This work shifts the paradigm from proprietary systems to a democratized approach where any conservation team can access the tools they need.
Partners recently confirmed that the ecosystem is rapidly recovering after removing invasive rats from Ulong Island in 2023-2024. Acoustic monitoring reveals dramatically increased seabird calls from Brown Noddies, White Terns, and Bridled Terns, while Endangered Palau Ground Doves (including chicks) are now spotted in areas where they were never previously recorded.
As part of the Island-Ocean Connection Challenge, Ulong demonstrates that restoring ecosystems also protects the irreplaceable cultural heritage within them, including ancient caves with pre-colonial paintings and pictographs that tell the story of Palau’s history.
A gecko species previously known only from ancient fossils has been found reappearing on Rábida Island in the Galápagos, confirmed through peer-reviewed research published in PLOS ONE in June 2025.
The Leaf-toed Gecko reappeared just one year after invasive rodents were removed from the island in 2011, and genetic analysis now reveals the population is an evolutionarily distinct unit critical for conservation.
The Island Nation of Tuvalu restored critical habitats for Endangered Green Sea Turtles, native seabirds, and the coconut agroforests that support local livelihoods after successfully removing invasive rats from six islets across Nukufetau Atoll and Funafuti.
Communities are already seeing the difference. Birds and coconut crabs are flourishing again, mosquito populations have collapsed, and yellow crazy ants have nearly disappeared. This community-led initiative shows how Island Nations are driving transformative impact across the globe.
Our team traveled to a number of conferences this year including the United Nations Ocean Conference, the IUCN World Conservation Congress, RedLAC in Chile, and more. Throughout it all, we shared inspiring messages of hope proving that islands are solutions.
These gatherings are essential to attend so we can ensure that islands are represented in global policy decisions and that island voices and needs are heard.

The seed of hope is taking root, but we need you to help spread it.
YES, LET’S DO IT! I’M READY TO DONATE.
Islands are home to more than half of the world’s marine biodiversity and seven of the planet’s ten coral reef hotspots.
When island ecosystems thrive, they feed reefs, fisheries, and communities that depend on them. Our restoration work this year strengthened over 100 km (~ 62 miles) of coastline and we launched two monitoring programs to track how island restoration makes coastal ecosystems more productive and resilient to climate change.
The Island-Ocean Connection Challenge (IOCC) is a volunteer collective of partners with a goal to restore and rewild at least 40 globally significant island-ocean ecosystems from ridge to reef by 2030. This year, we announced five new islands, including three in Aoteroa New Zealand, Chincha Norte Island in Peru, and Robinson Crusoe Island in Chile. This brings us to a total of 22 islands, making us half way to our goal. As co-founders of this global movement, we are incredibly proud of the strides we’ve made this year.
We are also thrilled to welcome new partners like Conservation X Labs to the fold.
Check out our first ever IOCC Impact Report.
Islands don’t usually get the spotlight they deserve. We’re trying to change that.
The urgent challenges of the triple planetary crisis — biodiversity loss, declining ocean health, and climate change — are sparking bold innovation, deep collaboration, and some of the most remarkable ecological recoveries on Earth. Island Nations and communities are leading a vast number of these initiatives, showing their unwavering resilience, hope, and leadership.
In response to this, we introduced an official motion in 2025 for a United Nations Decade of Island Resilience. Islands are biodiversity hotspots and hope spots for the planet, and our goal is to shine a light on the planet’s most vulnerable and invaluable ecosystems. Our call is being answered, the motion was adopted and is moving through the official IUCN process with 767 affirmative votes.

This year Ted Haffner and his family joined us on a trip to Puerto Rico where they visited Culebra and Vieques Islands. Guided by our staff and partners, they were able to roll up their sleeves for some hands-on conservation work like working to help protect sea turtles and monitoring shorebird nests.
Global progress for ocean protection is accelerating. The High Seas Treaty is moving toward implementation, setting the stage for safeguarding marine life in international waters. In the Pacific, French Polynesia designated its largest marine protected area yet, and The Soloman Islands, Vanuatu, and Papua New Guinea announced the world’s largest Indigenous-led MPA.
Across the sea, Chile announced the 350,000 km2 expansion of two of the world’s largest designated Marine Parks, Nazca-Desventuradas and Mar de Juan Fernández.
We work in partnership with local communities, nonprofit organizations, governments, scientists, and landowners to create lasting change for nature and people. Together, we combine knowledge, resources, and dedication to maximize impact.
Want to see the people behind the scenes? We’re a group of passionate, mission-driven individuals working to transform ecosystems that are on the brink of collapse. But we can’t do this work alone, it takes a team.
