We are committed to protecting and conserving biodiversity and natural habitats that are critical to the survival of many species.

Since 2001, Yagasu has focused on the conservation of endangered or vulnerable species. Through conservation programmes, Yagasu also works to protect rare species, be they animals, plants or micro-organisms. With the support of scientists and conservationists, we work to restore populations of these species and prevent them from becoming extinct.

After the 2004 tsunami, Yagasu organised a mangrove planting ceremony on the coast of Banda Aceh, which was severely damaged by the tsunami. In an effort to raise the spirit and awareness of the community, Yagasu involved elephants in the mangrove planting ceremony.

The elephant attraction during the mangrove planting in the area was a highlight and created excitement in the community. Apart from being a concrete step to introduce the benefits of mangroves as tsunami barriers and amplifiers, the activity also aimed to provide entertainment for the people who were still traumatised by the earthquake and tsunami that occurred in their area.

Participation in post-tsunami rehabilitation activities

In a joint effort to rehabilitate areas affected by the 26 December 2004 tsunami in Aceh, the Sumatran Elephant Foundation (Yagasu), in collaboration with the Aceh Natural Resources Conservation Agency (BKSDA), took an innovative step by mobilising a team of elephants to assist in the removal of debris following the disaster. This decision was part of an overall effort to provide humanitarian assistance and support reconstruction efforts in the aftermath of the natural disaster that struck the Aceh region following the tsunami.


Yagasu showed creativity in its disaster response by mobilising its elephant team to help clear debris from the tsunami-hit coast. The elephants are specially trained to help move heavy materials and reach hard-to-reach areas.


The elephants use their natural skills to help move heavy debris and access areas that are difficult for heavy machinery to reach. The use of elephants brings uniqueness to the clean-up effort, creating an environmentally friendly and effective solution.

Biodiversity in the mangrove areas

Mangrove Snake

Venomous snake species found in Southeast Asia, especially in mangrove areas

Munia Bird

They are often found in tropical and subtropical regions of Asia, Africa, and Australia


Conservation efforts are being made to protect these species and their habitats in coastal areas

Species & Habitat Conservation

Mangrove crabs, also known as mud crabs, are a type of crab commonly found in mangrove forests and muddy areas in coastal regions. Mangrove crabs have hard shells, wide crab legs, and colors that vary from brown to purplish red. They play an important role in mangrove forest ecosystems with various benefits, such as controlling populations of other organisms, recycling nutrients, and assisting in bioremediation and habitat preservation. Mangrove crabs are also a source of food and income for many local communities in coastal areas. Mangrove crabs are a species that must be protected and conserved to maintain the balance of coastal ecosystems.

Oysters are a type of mollusk that live in marine environments, usually found on the seafloor or on muddy substrates. They have a skeletal shell with two symmetrical shells that can open and close. Oysters are filter feeders, which means they filter food particles from the water through their gills. The main food of oysters is phytoplankton and zooplankton. Oysters play an important role in coastal ecosystems by helping to clean the water and creating habitats for other organisms. In addition, oysters are also a popular food in various seafood dishes.

Species & Habitat Conservation

Habitat conservation is an important part of our efforts. Healthy and well-maintained habitats are key to species survival. We work to maintain and restore natural habitats, such as forests, rivers and coral reefs, so that their ecosystems remain balanced and support the lives of diverse organisms.

We’d love to hear from you. If you would like to contribute, collaborate, or have further questions regarding our conservation programs, please do not hesitate to contact us.
