Caribbean wildlife populations decline by 95% in WWF 2026 report

GREAT BAY--Latin America and the Caribbean have recorded the steepest decline in monitored wildlife populations anywhere in the world, with an average decrease of 95 percent between 1970 and 2022, according to the World Wide Fund for Nature's (WWF) newly released Living Planet Report 2026. The findings raise serious concerns for Caribbean countries and territories, where healthy marine ecosystems, coastal habitats and biodiversity are closely connected to tourism, fisheries, food security and protection against climate-related disasters.

The report, released on October 7 and titled The Science of Hope, identifies Latin America and the Caribbean as the region experiencing the most severe average decline in the populations studied. The regional figure is considerably worse than the worldwide average decline of 73 percent recorded over the same period.

The findings are based on the Living Planet Index, developed by the Zoological Society of London, which examines 35,803 monitored wildlife population trends involving 5,790 species of mammals, birds, fish, reptiles and amphibians.

WWF emphasizes that the 95 percent decline does not mean that 95 percent of all animals in Latin America and the Caribbean have disappeared. Rather, it reflects the average proportional reduction in the size of wildlife populations included in the monitoring program.

The figure also represents Latin America and the Caribbean collectively and should not be interpreted as a separate measurement for the Caribbean islands or any individual territory.

Nevertheless, WWF's findings illustrate the scale of biodiversity loss affecting a region containing some of the world's richest natural ecosystems.

Caribbean Ecosystems Under Growing Pressure

The report identifies habitat loss and degradation as the most frequently reported threats to wildlife, followed by overexploitation of species, climate change, pollution, invasive species and disease.

Across Latin America and the Caribbean, forests, wetlands and grasslands have been damaged or destroyed, while rivers and freshwater habitats have been affected by land development, agricultural expansion and changes to natural waterways.

The region is also highly vulnerable to climate change, including extreme heat, prolonged droughts and increasingly intense hurricanes.

For Caribbean islands, these concerns extend directly to the marine and coastal environments that sustain local economies and communities.

Coral reefs, mangrove forests and seagrass beds provide breeding grounds, feeding areas and shelter for marine species. They also help protect coastlines from waves and storm damage, while supporting fishing, diving, snorkeling and other tourism-related activities.

Their continued deterioration therefore has consequences beyond wildlife conservation, potentially affecting employment, economic activity, coastal protection and the long-term sustainability of island communities.

Dutch Caribbean Conservation Efforts Highlighted

In its Caribbean-focused communication accompanying the 2026 report, WWF Netherlands specifically highlighted conservation work across the Dutch Caribbean and the importance of protecting the ecosystems upon which the islands depend.

WWF-NL works with local conservation organizations, researchers, governments and communities to protect and restore natural environments throughout the Dutch Caribbean.

Its regional conservation program places particular emphasis on climate-resilient coastal areas and the protection and recovery of marine species, including sea turtles, whales, dolphins and sharks.

The organization identifies coral reefs, mangroves and seagrass beds as essential habitats that support marine biodiversity, provide natural coastal defenses and contribute to the ability of islands to withstand climate-related threats.

WWF-NL focuses on conservation priorities in Bonaire, St. Eustatius and Saba, while also working with local partners in Aruba, Curaçao and St. Maarten.

Roxanne-Liana Francisca, Lead of WWF-NL's Dutch Caribbean Program, emphasized the direct relationship between environmental protection and the well-being of island communities.

“Livelihoods and general wellbeing in the Dutch Caribbean is intimately linked with healthy ecosystems,” Francisca stated.

She also acknowledged the work of local conservation organizations, both large and small, that continue raising public awareness while protecting and restoring the islands' natural resources.

The Dutch Caribbean conservation efforts are particularly relevant to the WWF findings because the islands depend heavily on coastal and marine environments that face increasing pressure from warming seas, pollution, development and other human activities.

However, the 2026 Living Planet Index does not provide a separate 95 percent decline figure for the Dutch Caribbean. The regional statistic should therefore not be used as a measurement of wildlife losses on St. Maarten, Curaçao, Aruba, Bonaire, Saba or St. Eustatius individually.

Green Sea Turtle Recovery Offers Hope

Despite the serious findings, WWF's report presents encouraging evidence that wildlife populations can recover when conservation measures are sustained over time.

One example of particular relevance to the Caribbean is the recovery of the green sea turtle, a species found throughout the region.

In 2025, the green sea turtle became the first marine turtle to move from Endangered to Least Concern on the International Union for Conservation of Nature's Red List.

The improvement followed more than 50 years of conservation work across over 80 countries where green sea turtles nest.

Protection of nesting beaches, stronger safeguards for eggs and nesting females, measures to reduce accidental capture in fishing equipment, enforcement against illegal harvesting and cooperation with local communities all contributed to the species' recovery.

The achievement demonstrates that long-term conservation programs can produce measurable improvements, even for species previously facing serious population declines.

For Caribbean territories, where sea turtles depend on both nesting beaches and healthy marine habitats, the recovery offers an example of the benefits of sustained environmental protection.

Nevertheless, the improved global conservation status of green sea turtles does not mean that all regional populations have recovered or that threats to individual nesting beaches have disappeared.

Coastal development, artificial lighting, pollution, fishing activities and the loss of suitable nesting habitats remain important conservation concerns.

Protecting Nature Means Protecting Caribbean Livelihoods

One of the central messages of the WWF report is that the consequences of biodiversity loss extend beyond the disappearance of animal populations.

Nature provides services upon which economies and communities depend, including food production, water resources, climate regulation and protection from natural hazards.

In the Caribbean, this relationship is especially important because many islands rely on relatively small coastal areas for residential development, tourism infrastructure, fishing activities and recreational opportunities.

The continued degradation of reefs, mangroves and other coastal habitats can increase the vulnerability of these communities while undermining the natural resources that support economic activity.

WWF also emphasizes that conservation cannot succeed through isolated wildlife protection efforts alone. Its report calls for changes in how societies produce food, generate energy and direct financial investment, identifying these systems as major drivers of environmental damage.

The organization advocates sustained conservation financing, stronger environmental policies and closer collaboration among governments, businesses, researchers and local communities.

Of particular relevance to Caribbean fishing communities, the report recognizes that fisheries conservation can produce stronger results when local fishers participate in developing and enforcing protective measures.

Such cooperation can help protect marine resources while ensuring that conservation initiatives take account of the livelihoods of those who depend on them.

A Critical Period for Caribbean Biodiversity

The Living Planet Report 2026 comes as countries approach the 2030 deadline established under the Kunming-Montreal Global Biodiversity Framework, an international agreement intended to halt and reverse biodiversity loss.

WWF warns that conservation efforts must accelerate if those objectives are to be achieved.

For the Caribbean, the findings reinforce the importance of regional cooperation, effective environmental management, stronger protection of marine and terrestrial habitats and sustained investment in conservation.

At the same time, the recovery of species such as the green sea turtle offers evidence that coordinated action can reverse environmental decline.

The report's central message is that the loss of nature is not inevitable, but reversing it requires continued commitment, resources and changes to the activities responsible for environmental damage.

For Caribbean islands, protecting biodiversity is therefore not simply an environmental objective. It is closely connected to protecting livelihoods, strengthening economic resilience and preserving the natural resources upon which future generations will depend.
