Conserving the Leuser Ecosystem

Maintain the Leuser ecosystem

Leuser ecosystem

The Leuser Ecosystem, located on the island of Sumatra in Indonesia, is one of the most biodiverse and ecologically important areas in the world. Spanning over 2.6 million hectares, this unique ecosystem is home to a wide variety of plant and animal species, many of which are found nowhere else on Earth. Conservation of the Leuser ecosystem is crucial for the preservation of biodiversity, climate change mitigation and the well-being of local communities. In this article, we will explore the importance of conserving the Leuser Ecosystem and the efforts being made to protect this invaluable natural treasure.

The importance of the Leuser ecosystem

The Leuser Ecosystem is a UNESCO World Heritage Site and is recognized as one of the last places on Earth where endangered species such as the orangutan are found in the wild of Sumatran, the Sumatran elephant, the Sumatran rhino and the Sumatran tiger. In addition to its rich wildlife diversity, the Leuser Ecosystem provides essential ecosystem services such as clean water, climate regulation, and carbon sequestration.

Leuser biodiversity


The Leuser Ecosystem is home to approximately 4,500 plant species, 300 bird species and 120 mammal species, making it one of the most biodiverse regions in Southeast Asia. Its vast range of flora and fauna contributes to the overall health of the ecosystem and provides irreplaceable genetic resources.

Climate regulation

The forests of the Leuser ecosystem play a crucial role in regulating local and global climate. Dense vegetation acts as a carbon sink, absorbing and storing large amounts of carbon dioxide, helping to mitigate climate change.

Water resources

The Leuser Ecosystem is the source of 90% of the fresh water for the millions of people living in the region. Forests act as a natural water filtration system, maintaining water quality and providing a reliable supply to human and animal populations.

Threats to the Leuser ecosystem

Despite its ecological importance and protected status, the Leuser ecosystem faces serious threats from human activities such as illegal logging, poaching, agricultural expansion and infrastructure development. These activities not only endanger the delicate balance of the ecosystem, but also endanger the livelihoods of local communities.


Large-scale deforestation driven by the palm oil and pulpwood industries, as well as illegal logging, pose a significant threat to the Leuser ecosystem. This rampant deforestation leads to loss and fragmentation of habitats, threatening the survival of many endemic species.

Wildlife poaching

Illegal hunting and trade in endangered species within the Leuser Ecosystem continue to decimate wildlife populations. Demand for exotic animals, traditional medicines and wildlife products is fueling the illegal wildlife trade, further endangering already vulnerable species.

Infrastructure development

The construction of roads, dams, and other infrastructure projects within the Leuser Ecosystem disrupts the natural landscape and fragments habitats, making it difficult for wildlife to migrate and access essential resources. These developments also contribute to increased human-wildlife conflict and ecosystem degradation.

Conservation Efforts

Recognizing the urgent need to protect the Leuser Ecosystem, various local and international organizations, government agencies and community groups have worked tirelessly to conserve this invaluable natural heritage.

Legal protection

  • The Leuser Ecosystem is designated as a National Strategic Area for Environmental Protection and is legally protected under Indonesian law. Efforts to enforce these laws and regulations are essential to protect the ecosystem from illegal activities.
  • Collaboration with local government and law enforcement agencies to develop and implement effective enforcement mechanisms is crucial to combating illegal logging, poaching and encroachment.

Community involvement

  • Empowering local communities and indigenous peoples to participate in conservation initiatives and sustainable livelihood programs helps ensure their support and involvement in protecting the Leuser Ecosystem.
  • Engaging communities in ecotourism, agroforestry and sustainable agriculture projects offers alternative sources of income while promoting environmental management.

Sustainable development

  • Promoting sustainable land use practices, such as organic farming, agroforestry and community forest management, helps reduce deforestation and habitat destruction while meeting the economic needs of local communities.
  • Investing in green infrastructure, such as wildlife corridors and eco-friendly tourism facilities, contributes to habitat connectivity and sustainable economic growth in the region.


The Leuser Ecosystem is a valuable natural asset that has immense ecological, cultural and economic value. Protecting and conserving this vital ecosystem is not only a responsibility but a necessity for the well-being of current and future generations. Through collaborative efforts, effective policy implementation and community engagement, we can ensure the long-term sustainability of the Leuser ecosystem and preserve its unprecedented biodiversity for years to come.
