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.”

KUALA LUMPUR, 26 JUNE 2023 – Reef Check Malaysia is deeply concerned about the long term damage to biodiversity that will result from construction of the proposed new airport on Tioman Island.

“At a time when the international community is starting to realise the implications of biodiversity loss, we are worried that the long term effect on the island’s natural resources – and community – will be substantial”, said Julian Hyde, General Manager of Reef Check Malaysia.

The main attraction of Tioman Island is its natural environment such as its coral reefs and white sandy beaches, as well as untouched rainforest. These ecosystems are home to endemic and endangered species, an important part of the island’s biodiversity.

The proposed new Tioman Airport will be built on 460.50 acres, of which 76% will be on reclaimed land. The project’s components include land reclamation, quarrying, construction of revetments and hill cutting, as well as site work and preparation.

“Obviously there will be damage to ecosystems in the immediate vicinity of the site – not to mention the economic losses to businesses in the two villages adjacent to the project site. The EIA is clear about this. So there is going to be some loss of biodiversity”, Hyde says.

“But it goes further than that. Tioman currently receives around 250,000 visitors per year. Averaging that out over a 10-month season (with 2 months off for monsoon), that’s about 830 people per day. During busy periods rooms are hard to get; there are problems with water and electricity supply, and the incinerator struggles to deal with the load.

“The EIA suggests that up to 20 flights per day will operate at the new airport, with a capacity of up to 2,500 people. Three times the current volume. Where will they stay? How will they get there? How will that increase in waste and sewage be managed? What about water supply? The answers to these questions have important implications for the island’s biodiversity.”

The previous plan to build a new airport on Tioman was rejected as environmental impact assessment studies showed that the project would severely damage the environment through land reclamation and other activities.

Hyde says: “In terms of advancing the policy to develop the tourism sector, and the state’s development policy, a better management approach would consider protecting the islands natural assets, because what tourism means when we talk about Tioman island is its beautiful natural resources. Developing tourism cannot exclude the protection of the natural environment.”

“A more detailed study is needed to better understand the impact of more tourists. This should include not just the immediate physical impact at the site, but how a four-fold increase in visitors will affect both the island’s biodiversity and its community.”
