The IUCN Green List of marine protected areas program added Saudi Arabia’s Farasan Islands Reserve while Colombia’s Malpelo Sanctuary renewed its status.
Marine protected areas are growing rapidly around the world, but conservation experts increasingly emphasize that protection on paper is not enough. The real challenge is ensuring these areas are effectively managed, scientifically monitored, and genuinely safeguarding biodiversity.
That is the goal of the International Union for Conservation of Nature (IUCN) Green List of marine protected areas program, an international certification system that recognizes protected areas that meet high standards for conservation effectiveness and governance.
In April 2026, ICN announced two major updates to the program. Saudi Arabia’s Farasan Islands Reserve joined the Green List for the first time, while Colombia’s Malpelo Fauna and Flora Sanctuary successfully renewed its status. Together, the additions bring the IUCN Green List marine protected areas network to 113 listings across more than 240 protected sites in 23 countries.
The Green List differs from many traditional conservation designations because it focuses not just on legal protection, but on measurable outcomes and long-term management quality. Protected areas seeking Green List status are evaluated using detailed criteria covering governance, biodiversity outcomes, community involvement, enforcement, planning, and ecological monitoring. In other words, the program aims to answer an increasingly important question: are protected areas actually working?
The newly added Farasan Islands Reserve lies in the southern Red Sea off Saudi Arabia’s coast and includes coral reefs, seagrass beds, mangroves, and important marine habitats. The region supports species such as dugongs, sea turtles, and migratory birds, and serves as an important breeding area for marine life.
The reserve’s inclusion in the IUCN Green List of marine protected areas program reflects years of work focused on ecosystem monitoring, habitat management, and balancing conservation with local livelihoods.
Meanwhile, Colombia’s Malpelo Fauna and Flora Sanctuary renewed its Green List certification after meeting continued performance standards. Located in the eastern Pacific Ocean, Malpelo is internationally known for its extraordinary marine biodiversity.
The remote sanctuary provides habitat for sharks, tuna, whales, sea turtles, and one of the world’s largest aggregations of hammerhead sharks. Malpelo is also recognized as a UNESCO World Heritage Site and has become one of the most important marine conservation areas in the Tropical Eastern Pacific.

Renewing Green List status is not automatic. Protected areas must demonstrate ongoing management effectiveness and continue meeting rigorous standards over time. That requirement is central to the philosophy behind the IUCN Green List of marine protected areas initiative. Rather than acting as a one-time label, the system encourages continuous improvement and accountability.
Globally, marine ecosystems face mounting pressures from overfishing, warming oceans, pollution, shipping, habitat destruction, and climate change. As countries race to meet international biodiversity targets such as protecting 30% of land and oceans by 2030, scientists have warned that simply increasing the number of protected areas may not guarantee meaningful conservation outcomes.
Some marine protected areas exist largely on paper without sufficient enforcement or management resources. These are sometimes called “paper parks.” The Green List was created partly in response to those concerns, as the initiative aims to identify protected areas that are not only designated but actively functioning as effective conservation systems.
Importantly, the program also highlights the role of local communities and Indigenous participation. Green List criteria include governance standards that encourage transparency, stakeholder involvement, and equitable management practices. This reflects a broader shift in global conservation thinking away from exclusionary conservation models toward more collaborative approaches.
The growth of the IUCN Green List of marine protected areas network also demonstrates increasing international cooperation around conservation standards. Protected areas from very different ecosystems, from African savannas to Pacific coral reefs, are now evaluated through a shared framework focused on measurable ecological outcomes. Supporters say this creates stronger incentives for governments and conservation managers to improve practices and share knowledge internationally.
Marine protected areas themselves are becoming increasingly important in climate resilience strategies. Healthy marine ecosystems such as coral reefs, mangroves, and seagrass meadows store carbon, protect coastlines from storms, and support fisheries relied upon by millions of people worldwide.
At the same time, marine biodiversity is declining rapidly in many regions. Overfishing, coral bleaching, plastic pollution, and warming oceans are placing intense pressure on marine ecosystems globally. Conservationists, therefore, argue that expanding and improving marine protected areas is essential for maintaining ocean resilience.
However, researchers also emphasize that marine protection alone cannot solve ocean degradation without broader climate action and sustainable resource management. Even well-managed marine reserves remain vulnerable to rising sea temperatures and acidification caused by global greenhouse gas emissions.
Still, the IUCN Green List of marine protected areas offers one model for improving conservation effectiveness in the face of these challenges. Rather than focusing only on the quantity of protected areas, the initiative emphasizes quality, accountability, and long-term ecological outcomes.
For the Farasan Islands Reserve and Malpelo Sanctuary, inclusion on the Green List represents international recognition of that effort. More broadly, the growing network reflects an evolving understanding that conservation success depends not just on drawing boundaries on maps, but on how ecosystems are actually protected and managed over time.
As global biodiversity targets expand, that distinction may become increasingly important. The future of marine conservation will likely depend not only on how much of the ocean is protected, but on whether those protections truly work.
