Floreana tortoise restoration marks historic milestone as 158 juvenile giant tortoises with ancestral lineage walk landscapes where their species disappeared in the mid-1800s, beginning the largest ecosystem recovery initiative in Galápagos history.
Floreana tortoise restoration achieved a breakthrough when giant tortoises returned to Floreana Island for the first time in more than 180 years. The release of 158 juvenile tortoises represents the first of 12 native species scheduled for reintroduction under the Floreana Ecological Restoration Project. The initiative stands as the most ambitious ecosystem recovery effort ever undertaken in the archipelago.
The Floreana Giant Tortoise (Chelonoidis niger niger) was driven to extinction in the mid-1800s. Its return signals a major turning point for Floreana and marks the beginning of a new phase of rewilding on the Galápagos Islands, home to approximately 160 residents.
Ecuador’s Ministry of Environment and Mines leads the project through the Galápagos National Park Directorate and the Galápagos Biosecurity and Quarantine Agency. Co-executing partners include Fundación Jocotoco, the Charles Darwin Foundation, and Island Conservation, with Galápagos Conservancy supporting the tortoise reintroduction.
Lorena Sánchez, Director of the Galápagos National Park, explained that after several years of sustained, science-based work, the Floreana tortoise restoration reflects a long-term vision focused on progressively restoring the ecological functionality of Floreana’s ecosystems.
The Floreana community has been deeply involved in achieving this milestone. Residents participated in planning workshops, supported biosecurity measures, and engaged in long-term ecological monitoring. Community engagement already contributed to the rediscovery of the Galápagos Rail (Laterallus spilonota), a rare bird that had not been recorded on the island since Charles Darwin’s first visit.
Verónica Mora, Community Representative from Floreana Island, noted that for generations, the island had no giant tortoises. Their return shows what is possible when a community leads, and many partners come together with shared purpose. Local livelihoods, from tourism to agriculture and fishing, depend on the health of this island.
The tortoises released represent decades of scientific research. Genetic studies conducted in the early 2000s revealed that some tortoises living on Wolf Volcano to the north of Isabela Island carried ancestry from Floreana. These individuals represented the last living descendants of a lineage long believed lost, likely due to historical whaling practices.
Through carefully managed breeding programs, these individuals were raised to form a population genetically as close as possible to the original Floreana giant tortoise. Hugo Mogollón, President and CEO of Galápagos Conservancy, stated that the release represents the culmination of years of genetic research and conservation collaboration.
As keystone species, tortoises help maintain open habitats, promote native plant growth, and create conditions that support entire ecosystems. Their absence on Floreana altered ecological processes for nearly two centuries. The Floreana tortoise restoration is expected to help restore those processes naturally and drive natural regeneration that supports a wide range of native plants and animals.
Rakan Zahawi, Executive Director of the Charles Darwin Foundation, emphasized that giant tortoises are a critical part of ecosystem function. By dispersing seeds, shaping vegetation, creating micro-habitats such as wallows, and influencing how landscapes regenerate, they help rebuild ecological processes that many other species depend on.
The Floreana tortoise restoration is expected to strengthen the land-sea connections. By dispersing seeds and opening habitats, tortoises help improve nesting and feeding conditions for birds, including species slated for future reintroduction. Healthy seabird populations contribute nutrients that support surrounding marine ecosystems, including coral reefs and fisheries.
Dr. Penny Becker, CEO of Island Conservation, noted that this decade of collaborative work has yielded results that couldn’t have been possible without all partners working together. Seeing tortoises walk freely on Floreana once again after more than 180 years shows what’s possible when local partners, global experts, and the community share a vision for recovery.
With the first species successfully reintroduced, project partners will continue to evaluate conditions for the next phase of rewilding. This includes iconic species such as the Floreana mockingbird, Floreana racer snake, vegetarian finch, and little vermilion flycatcher. Each species plays specific ecological roles that contribute to the overall health and function of the ecosystem.
The Floreana tortoise restoration is grounded in a community-first vision developed with and for the people of Floreana. The approach focuses on the long-term well-being of both the island’s ecosystems and livelihoods. This model demonstrates how ecological restoration can proceed successfully on inhabited islands when local residents remain central to planning and implementation.
Once fully restored, Floreana will stand as the largest ecological restoration project ever undertaken in Galápagos and serve as a global example. The comprehensive approach includes the eradication of three invasive mammal species, habitat restoration, and reintroduction of 12 endemic species. These combined efforts aim to restore the ecological functionality and resilience of this unique island ecosystem.
The project received support from numerous organizations, including Bell Laboratories Inc., Blue Action Fund, Global Environmental Facility, Conservation International Foundation, Development Bank of Latin America, Durrell Wildlife Conservation Trust, and many others. This broad coalition reflects the project’s significance for global conservation efforts.The success of Floreana tortoise restoration offers hope for similar rewilding initiatives on other islands worldwide. The project shows that even species believed extinct can return when sufficient genetic material remains and when communities, scientists, and governments collaborate with long-term commitment. The ecological processes these tortoises will restore extend beyond the species itself, supporting entire webs of life across island landscapes and surrounding waters.
