OMECS refers to geographically defined spaces that are managed in ways that support long-term biodiversity conservation outside formal protected areas.
These spaces can include indigenous lands, sacred natural sites, community-managed territories, forests, wetlands, coastal areas, and other places where local management practices contribute to the conservation of ecosystems and species.
The central idea behind OMECS is that important biodiversity does not exist only inside officially designated national parks, wildlife reserves, or other formal protected areas. Communities and Indigenous peoples may manage lands and waters in ways that maintain ecological processes, protect habitats, and conserve species even when those areas do not have formal protected-area status.
OMECS therefore represents a broader way of considering conservation beyond conventional protected-area boundaries.
Understanding Conservation Outside Protected Areas
Traditional conservation systems have often focused on formally designated protected areas.
Examples include:
- National parks
- Wildlife sanctuaries
- Nature reserves
- Marine protected areas
- Conservation reserves
- Other legally designated conservation zones
These areas generally have defined boundaries, management objectives, and legal or institutional frameworks.
However, many ecologically important landscapes fall outside these formal systems. Some may be managed by Indigenous communities, local communities, private landowners, religious institutions, or other groups.
If these places are managed in ways that contribute to biodiversity conservation, they can provide meaningful ecological benefits even without being classified as conventional protected areas.
This broader approach is important because biodiversity is distributed across entire landscapes rather than being confined to officially protected sites.
Indigenous Lands and Biodiversity
Indigenous lands are an important example of areas that can contribute to biodiversity conservation.
Many Indigenous peoples have long-standing relationships with their territories and have developed practices for managing forests, grasslands, rivers, wetlands, coastal ecosystems, and other environments.
These practices can include:
- Sustainable harvesting
- Seasonal resource use
- Protection of particular habitats
- Restrictions on hunting or fishing
- Controlled burning
- Protection of culturally important species
- Maintenance of sacred natural areas
- Community rules governing resource use
The effectiveness and ecological impact of these practices vary from place to place. OMECS therefore focuses on the conservation outcomes and management of a particular area rather than assuming that every Indigenous or community-managed territory automatically functions as a conservation area.
Sacred Natural Sites
Sacred natural sites provide another example of geographically defined spaces that may contribute to biodiversity conservation.
A sacred site may consist of a forest, mountain, river, wetland, spring, island, cave, or other natural feature regarded as culturally or spiritually significant by a community.
Cultural rules may restrict activities such as:
- Cutting trees
- Hunting
- Fishing
- Grazing
- Mining
- Construction
- Collection of natural resources
Such restrictions can sometimes result in habitats being maintained over long periods.
The conservation value of a sacred site can therefore emerge from the interaction between cultural traditions and environmental stewardship.
OMECS and Community Conservation
OMECS can also encompass areas managed by local communities.
Community-based conservation involves local people participating in decisions about the use and protection of natural resources. Depending on the circumstances, communities may establish rules concerning forests, fisheries, grazing lands, wildlife, or water resources.
For example, a community may designate part of a forest where harvesting is restricted. Another community may establish seasonal fishing rules that allow fish populations to reproduce.
These arrangements can contribute to biodiversity while also supporting local livelihoods and cultural practices.
How OMECS Differ From Protected Areas
The distinction between OMECS and formal protected areas is important.
A protected area generally has a clearly recognized legal or institutional status specifically connected to conservation.
OMECS, by contrast, refers to geographically defined spaces whose management contributes to biodiversity conservation even though they exist outside formal protected-area systems.
This does not mean that OMECS have no rules or governance. They may have detailed customary laws, community regulations, cultural practices, or other management systems.
The difference lies primarily in their status and governance framework.
OMECS and Other Effective Conservation Approaches
The concept of OMECS is closely related to international discussions about conservation outside protected areas.
A particularly important term in global conservation policy is Other Effective Area-Based Conservation Measures (OECMs).
An OECM is an area outside a protected area that is governed and managed in ways that achieve positive and sustained long-term outcomes for the conservation of biodiversity, together with associated ecosystem functions and services and, where applicable, cultural, spiritual, socioeconomic, and other locally relevant values.
OMECS, as described in the context of geographically defined conservation spaces, can therefore be discussed alongside broader approaches to recognizing conservation that occurs outside formal protected areas.
However, terminology should be checked carefully in any specific policy or scientific context because OMECS and OECMs are not automatically interchangeable terms.
Why Areas Outside Protected Areas Matter
A major reason for recognizing conservation outside formal protected areas is that protected areas alone cannot encompass every important ecosystem.
Wildlife often moves between different habitats. Rivers cross administrative boundaries. Migratory species may travel across countries and between protected and unprotected landscapes.
Similarly, ecological processes such as pollination, seed dispersal, water flow, fire regimes, and nutrient cycling operate across large areas.
Conservation efforts outside protected areas can therefore help maintain ecological connectivity between formally protected sites.
Ecological Corridors
OMECS can potentially contribute to ecological connectivity.
An ecological corridor is an area that helps animals and plants move between habitat patches. Maintaining connectivity can be particularly important when natural habitats have become fragmented by roads, agriculture, settlements, or other forms of development.
A community-managed forest between two protected areas, for example, could provide habitat through which wildlife moves between larger conservation areas.
Such areas do not necessarily need to be formally designated as protected areas to provide ecological value.
Supporting Threatened Species
Geographically defined conservation areas outside protected areas may also provide habitat for threatened or declining species.
A community may protect a forest because it contains culturally important trees, while simultaneously providing habitat for birds, mammals, insects, reptiles, amphibians, and plants.
Similarly, a sacred wetland may be protected because of its cultural significance while also providing breeding habitat for aquatic species.
The conservation benefits depend on the actual ecological conditions and management practices of each site.
OMECS and Cultural Values
An important characteristic of many areas outside formal protected-area systems is the connection between biodiversity and cultural values.
For Indigenous peoples and local communities, landscapes may have significance beyond their ecological resources.
A particular mountain might have spiritual importance. A forest might contain culturally important plants. A river may be associated with traditional practices or community identity.
Recognizing these values can broaden conservation beyond a purely ecological framework.
At the same time, conservation initiatives should respect the rights, governance systems, and decision-making authority of the communities connected to these territories.
The Role of Indigenous Knowledge
Indigenous and local knowledge can provide valuable information about ecosystems and species.
Knowledge accumulated over generations may include observations about:
- Animal behavior
- Plant characteristics
- Seasonal changes
- Water availability
- Fire patterns
- Migration
- Weather
- Sustainable harvesting
- Habitat conditions
When appropriately recognized and protected, such knowledge can complement scientific monitoring.
However, Indigenous knowledge should not be treated simply as a resource to be extracted for conservation projects. Ethical approaches require respect for communities’ rights, consent, cultural practices, and control over their knowledge.
OMECS and Sustainable Resource Use
Conservation does not necessarily mean that every human activity must be excluded from an area.
Some geographically defined conservation spaces may permit carefully managed activities such as:
- Fishing
- Hunting
- Gathering
- Agriculture
- Grazing
- Forestry
- Tourism
The key question is whether management practices maintain biodiversity and ecological functions over the long term.
In some cases, sustainable use may be an integral part of the area’s conservation system.
Monitoring Conservation Outcomes
Identifying an area as contributing to conservation is not enough by itself. Long-term monitoring can help determine whether biodiversity objectives are actually being achieved.
Monitoring may examine:
- Species populations
- Habitat condition
- Forest cover
- Water quality
- Ecosystem health
- Wildlife movement
- Threats and pressures
- Changes in land use
Community members may participate in monitoring alongside scientists, conservation organizations, or government agencies.
Reliable monitoring can help identify whether management practices are working and where adjustments may be needed.
Challenges in Recognizing OMECS
Although conservation outside formal protected areas can provide significant benefits, there are challenges.
Unclear Boundaries
Some community-managed or culturally important areas may not have precisely mapped boundaries.
Clear geographic definition can be important when assessing conservation outcomes.
Changing Land Use
Development, agriculture, mining, infrastructure, and other activities can place pressure on areas that previously maintained biodiversity.
Governance
Effective conservation often depends on clear and legitimate governance arrangements. Conflicts can arise when multiple groups claim rights or responsibilities over the same territory.
Recognition
Areas that provide genuine conservation benefits may remain poorly documented or unrecognized in national conservation planning.
Long-Term Security
Conservation practices can be affected by political, economic, social, or environmental changes. Maintaining conservation outcomes over time therefore requires durable governance and resources.
OMECS and Conservation Planning
Recognizing geographically defined conservation spaces outside formal protected areas can improve landscape-level conservation planning.
Instead of looking only at national parks and reserves, planners can consider a broader mosaic consisting of:
- Protected areas
- Indigenous territories
- Community-managed forests
- Sacred natural sites
- Sustainable-use areas
- Ecological corridors
- Other conservation-focused landscapes
This approach can provide a more complete picture of how biodiversity is maintained across a region.
The Importance of Local Participation
Local participation is particularly important when conservation takes place on lands where communities live and work.
People who depend on an ecosystem for food, water, livelihoods, or cultural practices are directly affected by conservation decisions.
Successful approaches may therefore involve communities in:
- Defining conservation objectives
- Establishing management rules
- Monitoring biodiversity
- Resolving conflicts
- Sharing benefits
- Reviewing management practices
Respect for local governance can also help make conservation efforts more socially sustainable.
OMECS and the Future of Conservation
As global conservation efforts increasingly focus on protecting biodiversity across entire landscapes and seascapes, areas outside conventional protected areas are receiving greater attention.
The recognition of Indigenous stewardship, community conservation, sacred natural sites, and other forms of effective area-based management can help broaden the conservation toolkit.
The objective is not necessarily to replace protected areas. Instead, different conservation approaches can work together to maintain habitats, ecological connectivity, species populations, and ecosystem functions across larger landscapes.
Conclusion
OMECS refers to geographically defined spaces managed in ways that support long-term biodiversity conservation outside formal protected areas. Examples can include Indigenous lands, sacred natural sites, community-managed forests, wetlands, coastal areas, and other areas where management practices contribute to maintaining biodiversity.
These spaces demonstrate that conservation can occur through many forms of governance and stewardship, not only through officially designated parks and reserves.
Their potential importance extends from protecting habitats and species to maintaining ecological connectivity and preserving cultural relationships with nature. At the same time, each area needs to be considered individually, with attention to its actual management practices, conservation outcomes, governance arrangements, and the rights of the people connected to it.
By recognizing conservation efforts beyond formal protected-area boundaries, OMECS can form part of a broader understanding of how biodiversity is protected across landscapes and communities.
