Tengah Island Conservation (TIC) is a biodiversity management initiative located on the island’s Long Beach. Founded and partially funded by Batu Batu, TIC is dedicated to the research, rehabilitation and regeneration of our natural environment. 

Inform. Inspire. Involve.

About Tengah Island Conservation

BB - TIC.jpg

Batu Batu - Pulau Tengah is a sustainably-minded, off-grid private island resort in Johor, Southern Malaysia with a focus on generating profits through tourism to create a positive impact on the surrounding environment. We are passionate believers that sustainable tourism can be beneficial to the environment, local communities and remain profitable for the tourism business operators. With that in mind, we have set-up an integrated Conservation & Sustainability Department, under the name of Tengah Island Conservation (TIC), and currently employ 4 full-time scientists who are responsible for our projects and community outreach programs. We are currently in the process of spinning-off TIC into a standalone non-profit society under the Malaysian ROS.


Our Vision

Malaysian eco-systems, full of life and rich in biodiversity where Nature and local communities thrive side by side. 

Our Mission

Our mission is to improve, regenerate and preserve marine and terrestrial biodiversity through scientific research, management, training and outreach. By empowering local communities through education, engagement and employment in conservation projects, we aim to protect our environment for future generations. 

Our Objectives

We take a scientific and community-driven approach to all that we do to preserve the flora, fauna and marine eco-systems on and around Pulau Tengah and its surrounding islands. We do this through informing, inspiring and involving relevant stakeholders, government, biodiversity specialists, the tourism industry, and local community. 


Why we do what we do…

A quote from Mark Carwardine below summarises our inspiration to do what we are doing at TIC.

...while nature has considerable resilience, there is a limit to how far that resilience can be stretched. No one knows how close to the limit we are getting. The darker it gets, the faster we’re driving.
There is one last reason for caring, and I believe that no other is necessary. It is certainly the reason why so many people have devoted their lives to protecting the likes of rhinos, parakeets, kakapos, and dolphins. And it is simple this: the world would be a poorer, darker, lonelier place without them.
— Mark Carwardine, Last Chance to See
From where we stand, we are simply unable to ignore the fragility of our environment.
— Cher Chua-Lassalvy, Founder

Our Volunteers

Our conservation programmes are supported by volunteers, students and interns from all around the world. 

Volunteers join us for periods of nine weeks - starting at the end of February and ending in November. 

Our aim is to bring international students or recent graduates in biology, or any other related fields, providing them with useful knowledge and skills to keep building their career in conservation. The first two weeks of the programme are focused on intense training on corals, reef fish, marine turtle conservation and public engagement. After the training period, they help us to run all the different projects and collect valuable data around the Johor Marine Park. 

We also collaborate with local universities, offering paid internships for Malaysian students in order to promote local capacity building. These interns usually join us for three to six months, helping with all areas of the programme and gaining valuable skills and experience in the field of conservation.

Tengah Island Conservation Activities

  1. Conserve, protect and regenerate sea turtle populations, coral reefs and other marine and terrestrial biodiversity within Malaysia with a focus on the sustainability of tourism operations. 

  2. Develop sustainable relationships with local communities and organisations, encouraging eco-tourism practices, sustainable living and conservation of the Marine Park. 

  3. Educate tourists and local communities within Johor Marine Park on the need for and importance of marine and terrestrial conservation. 

  4. Work to empower local communities in the Johor Marine Park through education, involvement and employment in turtle conservation and eco-tourism projects in Johor.

  5. Connect tourism professionals, tourism stakeholders and conservation and biodiversity specialists to allow for the exchange of knowledge in order to promote and support the growth in tourism operations which support biodiversity. 


Our Projects


Hatchery and Sea Turtle Monitoring

The TIC scientists based at the Tengah Island Hatchery collect data on endangered Green and critically endangered Hawksbill turtles in an otherwise undocumented and unstudied region and share this openly with governmental agencies, turtle conservation NGOs and academic institutions. 


Coral Reefs

In addition to Tengah Island Hatchery, TIC runs a wider marine conservation programme which includes coral reef mapping on Pulau Tengah and other Johor Islands, coral reef surveys and monitoring, reef restoration and other habitat studies with published scientific reports distributed quarterly.

Baited Remote Underwater Video Stations (BRUVS) are a non-invasive camera survey technique that is increasingly being used to assess marine and aquatic ecosystems throughout the world. At TIC, BRUVS are used to understand the abundance, biodiversity and behaviour of shark and ray species in different habitats.

Beach and Underwater Clean Ups

TIC carries out beach and underwater cleanups with Batu Batu's guests and staff to remove marine debris and “ghost” fishing gear which wash up on our island and damage our coral reefs.

Organic Farm Project

Tengah Island Conservation (TIC) and Batu Batu are partnering with FOLO Farms and Ulu Permaculture to turn our food waste into compost and create food gardens which are 100% organic.


Beach Profile Monitoring

We monitor changes in the beach area caused by erosion or accretion patterns through temporal measurements of beach profiles. Beach profile data is used in numerous ways to guide decision making in coastal areas, such as monitoring beach nourishment and dune restoration projects and ensuring suitable nesting habitat for sea turtles.

Marine and Terrestrial Species Database

We are constantly adding on to our photo I.D. catalogue of all species of plants and animals found on and around the island.

Indigenous Tree Nursery

As part of a programme to reduce coastal and inland erosion, and to restore damaged areas of native forest, we have built an indigenous tree nursery.
