Ecologically or Biologically Significant Marine Areas (EBSAs) represent a critical tool in the global effort to safeguard the health of our oceans and their biodiversity. These areas are identified based on their ecological uniqueness and their role in supporting marine life. Introduced under the framework of the Convention on Biological Diversity (CBD), EBSAs aim to bring attention to regions that are vital for the survival and sustainability of marine ecosystems.
In the face of threats like climate change, overfishing, habitat destruction, and pollution, EBSAs have gained global attention as essential areas for conservation. With international goals like the 30×30 target—a commitment to protect 30% of the world’s land and ocean by 2030—becoming more pressing, EBSAs provide the scientific foundation for achieving meaningful marine conservation.
This article explores the significance of EBSAs, the processes behind their identification, their role in marine biodiversity, and the challenges of protecting them. Dive in as we unpack why EBSAs are essential for the planet’s health and how we can support their conservation.
What Are EBSAs?
Ecologically or Biologically Significant Marine Areas (EBSAs) are specific regions of the ocean identified for their ecological importance. These areas are recognized based on scientific criteria, such as hosting unique species, providing critical habitats for marine life, or showcasing significant biological productivity.
EBSAs differ from marine protected areas (MPAs). While MPAs are legally designated zones with enforcement mechanisms, EBSAs are primarily scientific classifications. Their purpose is to inform decision-making and guide conservation efforts, offering a foundation for sustainable management and protection strategies.
The Origin and Evolution of EBSAs
The concept of EBSAs emerged from the CBD in the early 2000s. Recognizing the need for focused efforts to protect marine biodiversity, the CBD developed a framework to identify and describe areas that play critical roles in maintaining healthy marine ecosystems.
Over time, the EBSA process has evolved significantly. Initially, it relied on regional workshops and scientific reviews, but recent advancements in technology, data collection, and stakeholder involvement have enhanced the process. Today, EBSAs are a central part of global discussions on marine biodiversity, contributing to initiatives like the Sustainable Development Goals (SDGs) and the Kunming-Montreal Global Biodiversity Framework.
Why Are EBSAs Important?
Oceans cover more than 70% of the Earth’s surface and are home to a diverse array of species and ecosystems. However, they are under unprecedented pressure from human activities. Climate change, overfishing, plastic pollution, and habitat degradation are just a few of the challenges threatening marine life.
EBSAs play a crucial role in addressing these challenges by spotlighting areas that are vital to the health of marine ecosystems. These areas often serve as:
- Breeding grounds for marine species
- Migration corridors for fish, birds, and marine mammals
- Feeding grounds that support diverse marine life
- Carbon sinks like mangroves and seagrass beds, helping combat climate change
By identifying and protecting these regions, EBSAs ensure the sustainability of marine ecosystems, support biodiversity, and safeguard the livelihoods of millions of people dependent on marine resources.
How Ecologically or Biologically Significant Marine Areas (EBSAs) Are Identified
The process of identifying Ecologically or Biologically Significant Marine Areas (EBSAs) is based on specific scientific criteria established by the Convention on Biological Diversity (CBD). These guidelines ensure that the selected areas are of high ecological value, meaning they play an essential role in marine biodiversity and warrant focused conservation efforts. By applying these criteria, the CBD helps prioritize areas most in need of protection, aiding in global efforts to sustain marine life.
Key Criteria for Identifying EBSAs
1. Uniqueness or Rarity
One of the main criteria for identifying EBSAs is the uniqueness or rarity of habitats, ecosystems, or species within a given area. EBSAs often contain habitats or species that are found nowhere else, making them irreplaceable on a global scale. For example, hydrothermal vents—unique deep-sea formations—are home to specialized organisms that thrive in high temperatures and extreme conditions. Protecting these unique environments is critical, as they support rare ecosystems that play specialized roles in the marine biosphere.
2. Special Importance for Life History Stages
Certain marine areas hold particular significance for specific life stages of various species. These areas are essential for breeding, feeding, or nursery purposes and are crucial to the survival of many marine populations. For instance, coral reefs serve as spawning grounds for a wide variety of fish species, providing safe environments where they can reproduce. Likewise, estuaries act as nurseries for juvenile marine species, offering them a protected space to grow before they move to open waters. Protecting these areas ensures the continuation of vital life cycles within marine ecosystems, supporting species diversity and population health.
Vulnerability, Fragility, or Sensitivity
Some ecosystems, such as coral reefs and seagrass meadows, are particularly vulnerable to environmental changes. Protecting these areas helps prevent irreversible damage to biodiversity.
Biological Productivity
High biological productivity is another key criterion. Upwelling zones, where nutrient-rich water rises to the surface, support abundant marine life and are often classified as EBSAs.

3. Biological Diversity
Regions that are rich in biodiversity, like the Coral Triangle, are often designated as Ecologically or Biologically Significant Marine Areas (EBSAs). These biodiversity hotspots are home to a diverse range of species and ecosystems, making them crucial for maintaining ecological balance. The Coral Triangle, for example, contains over 500 species of reef-building corals and is a vital habitat for marine life, including many endangered species. By prioritizing areas with exceptionally high biological diversity, the CBD aims to protect regions that serve as genetic reservoirs, supporting the health and resilience of marine ecosystems globally.
4. Naturalness
EBSAs also include areas that have remained largely untouched by human activity, preserving their original ecological characteristics. These “natural” areas offer insights into how ecosystems function without significant human impact, making them invaluable for scientific research and conservation efforts. Preserving these relatively undisturbed regions helps maintain natural biodiversity and ensures that these ecosystems can continue to provide essential services, like carbon storage and habitat for diverse species. By protecting these pristine environments, we can also create baseline references to measure the effects of human activities on marine ecosystems.
The Role of the Convention on Biological Diversity (CBD)
The CBD has been at the forefront of the EBSA initiative. By providing a framework and guidelines, the CBD ensures that the identification of EBSAs is based on robust scientific research and stakeholder engagement. Through workshops and global assessments, the CBD helps countries and regions highlight significant areas that require conservation.
The CBD also collaborates with international organizations such as the United Nations and the International Union for Conservation of Nature (IUCN) to integrate EBSAs into broader conservation policies. These partnerships strengthen the global commitment to marine biodiversity.
