Interactive Map Brings Insight into Malaysia’s Coral Reef Health

KUALA LUMPUR, 22 SEPTEMBER 2025 – An advanced interactive map compiling years of data on the health of Malaysia’s reefs from over 300 sites is now available on Reef Check Malaysia’s website.

The interactive map offers a comprehensive and dynamic view of reef conditions, specifically using data from the Reef Check survey methodology, which is widely recognized worldwide.

It provides a robust platform that visualizes data, displaying key indicators such as fish, invertebrates, and substrate data. The platform presents this information in an easy-to-understand format, helping users quickly identify areas of concern and track trends in reef health in Malaysia over the past five years.

The interactive map displays data on the health of Malaysia’s coral reefs.

The new platform was made possible through The APAC Digital Transformation Program by Infoxchange.

“This platform leverages the power of community involvement to gather extensive and diverse data sets. This approach democratizes data collection and encourages public participation, fostering a sense of ownership and responsibility towards reef conservation,” commented Theresa Ng, Chief Operating Officer of Reef Check Malaysia.

“The interactive map also provides timely updates on reef health indicators. This immediate access to current data allows stakeholders to make informed decisions quickly, enhancing the ability to respond to emerging threats,” Ng added.

The platform is designed with an intuitive user interface and is accessible via Reef Check Malaysia’s website. This ensures that users of all technical backgrounds can easily navigate the map, and access relevant information.

Alongside the interactive map, Reef Check Malaysia has also introduced an educational modules page, designed for teachers, students, and passionate individuals to learn more about marine conservation.

“We invite everyone to explore the map and educational modules,” added Ng. “We hope this platform and modules will help facilitate informed decision-making, promote sustainable practices, and ultimately contribute to the preservation and restoration of coral reefs, safeguarding these vital ecosystems for future generations.”

During this Covid-19 pandemic year, the Tioman Marine Conservation Group (TMCG) on Tioman Island were able to successfully remove 37 ghost nets weighing over 4,000 Kg, removed over 700 Crown-of-Thorns starfish, conducted over 60 reef surveys, and installed 15 mooring lines in the ocean.

TMCG, also known as the “ghostbusters” due their frequent ghost nets cleanups, began as a small group of five from Kampung Tekek and Kampung Air Batang in 2015, has now expanded to a total of 65 members spanning all seven villages on the Island.

The members are all local islanders who have expressed an interest in marine conservation and being a part of managing the island’s resources.

Born and raised on Tioman island, Shahir B Yaman, one of the founding TMCG member shares, “I am proud and thankful to have this opportunity to gain skills from the programme and now lead the TMCG. We are not only conducting conservation activities but also creating awareness among the community and acting as role models. TMCG is a good example for Malaysia on how local islanders can protect their island.”

Reef Check Malaysia (RCM) has organized various trainings to equip the TMCG members with skills and knowledge which they can apply to assist in day-to-day marine resource management activities, such as installation and maintenance of mooring buoys, removal of ghost nets and marine debris, bleaching monitoring, Crown-of-Thorns Starfish monitoring, coral rehabilitation, and so on.

The team is led by Alvin Chelliah, Senior Programme Manager of RCM. “We learned that protecting the ocean is beyond just coral reef monitoring and surveys and we had to look at initiatives that directly involve and impact the community. We slowly shifted our focus to participatory management – an approach where responsibilities are shared among various stakeholders, from local communities, government or non-government actors, to policymakers. And that is how the TMCG came about,” Alvin shares.

The training and setting up of the TMCG was fully sponsored by Yayasan Sime Darby. The group was later supported by the Department of Marine Parks Malaysia and is currently sponsored by a matching grant from the Ministry of Finance.

RCM hopes to strengthen the TMCG and replicate this success with communities on other islands, providing new livelihood opportunities that do not rely entirely on tourism, and at the same time strengthening reef conservation through a participatory approach to management.
