Ecosystems

This is where we feature the various ecosystems in Malaysia. From cloud forests to coral reefs, these are the rawest reasons we do environmental journalism. For each ecosystem, we tell the stories of not only the natural living and non-living components of these communities and systems, but also the human ones. Here, you can explore natural Malaysia in text, voice and photos, guided by the experience of those who know it well.

MANGROVE ECOSYSTEM

Living between sea and land are mangroves (‘bakau’), protectors of coasts, ‘reclaimers’ of land, nurseries for fish. An ecosystem that is at once wet and dry, brackish and saline, it is defined most by stilt roots and mudflats. But its biodiversity and ecosystem roles are larger and more complex than what meets the eye.

Awash in sea water twice daily, mangrove trees thrive in a challenging environment.

KARST ECOSYSTEM

Popularly referred to as limestone (‘batu kapur’), Malaysia’s remarkable karst landscape has been sculpted by centuries of action of water on soft rock. It is also home to unique life-forms and is part of human life. Coming up, we talk to those who know it well to celebrate its myriad facets, in our first ecosystem spotlight.
