A recent study has warned that the Myristica swamps of the Western Ghats, among the world's oldest surviving freshwater swamp forests, are on the cusp of extinction.
These are freshwater swamps dominated by evergreen trees of the family Myristicaceae, growing on waterlogged soil that stays inundated through the year.
In India they occur mainly in the Western Ghats, with smaller occurrences reported from the Andaman and Nicobar Islands and Meghalaya.
They regulate floods, recharge groundwater, sustain perennial stream flow and store more carbon than comparable non-swampy forest.
Logging, drainage, plantation expansion, fragmentation, invasive species and climate change have reduced a once-continuous network to small isolated pockets.
Permanent waterlogging drives oxygen out of the soil, and root systems must adapt or die. That is why Myristica swamp trees develop the conspicuous stilt roots and knee-shaped aerial roots that jut out of the mud: they are breathing structures, not anchors. This makes the ecosystem exceptionally sensitive to hydrology. Drain the valley, dam the stream upslope, or convert the catchment to plantation and the swamp does not merely shrink, it converts, because the specialist swamp trees cannot regenerate in drier soil while ordinary dryland species can move in. Studies of fragmented swamps record exactly this vegetation shift, which is why loss here is usually one-way.
Simple Analogy: A Myristica swamp is like a species that can only breathe through a snorkel. Lower the water and you have not just made life harder, you have removed the one condition under which it can exist at all.
The Ghats are one of the world's recognised biodiversity hotspots and a UNESCO World Heritage Site inscribed in 2012 as a serial property of component sites.
The 1971 convention covers forested wetlands as well as lakes and marshes, which is why researchers argue Myristica swamps deserve consideration under the Ramsar framework.
Kathalekan survived largely because it was treated as a sacred grove, an example of community institutions delivering conservation outcomes ahead of statutory protection.
The Sharavathi Valley Lion-tailed Macaque Sanctuary, formed by merging the Sharavathi sanctuary with the Aghanashini conservation reserve, protects habitat that includes swamp patches.
Flood moderation, groundwater recharge and carbon sequestration are textbook regulating services, and the swamps are a compact example for a Mains answer.
