From one sapling to 2,000: Kannur’s quiet mangrove comeback

Kannur’s backwaters and tidal creeks are part of a living shoreline—one where mangroves help stabilise banks, filter water and support fish and bird life. Yet even in regions known for mangrove patches, some species can quietly slip towards local disappearance. One such variety, locally called **Kannampotti** (*Excoecaria agallocha*), is now at the centre of a determined conservation effort led by Kannur-based mangrove conservationist **Parayil Rajan**.

Drawing attention to the plant’s shrinking presence in the district’s tidal landscape, Rajan has been working to expand its numbers through careful propagation and planting. From what began as safeguarding a single plant, his effort has reportedly grown to **around 2,000 plants**—a small but meaningful boost for a species he fears could otherwise fade out from local waterways.

A rare mangrove, a local mission Mangroves are often spoken of as a single green belt, but they are in fact a mix of species with different strengths and habitat preferences. When any one species becomes scarce, the ecosystem loses some of its diversity and resilience. Rajan’s concern about Kannampotti is rooted in this idea: that protecting the full mix of mangrove species is as important as increasing overall green cover.

Kannampotti (*Excoecaria agallocha*) is known in coastal ecology for thriving in tidal zones. In Kannur, its presence has been associated with the district’s creeks and estuarine edges—areas that are constantly shaped by saltwater intrusion, monsoon flows and changing sediment patterns.

Rajan’s initiative, reported by *The Hindu*, underlines a practical approach to conservation: identify a threatened local species, increase its propagation, and reintroduce it into suitable habitats so it can re-establish over time. The scale—moving from one plant to roughly 2,000—signals persistence, patience and a strong on-ground understanding of what these intertidal plants need to survive.

What conservation looks like on the ground Unlike large, one-time plantation drives, mangrove conservation tends to be a long game. Planting in tidal regions requires selecting appropriate sites, working with seasonal conditions, and protecting young plants as they take root. Even when saplings survive the initial months, the real test comes with repeated cycles of high tide, heavy rainfall and changing salinity.

Rajan’s work shows that local stewardship can make a measurable difference, especially for species that may not receive widespread attention. Efforts like these also help create awareness that mangroves are not merely “coastal trees” but critical infrastructure for coastal well-being.

While the report focuses on Kannampotti, the broader message is that small, targeted actions can help conserve biodiversity. Protecting a rare mangrove variety supports the wider habitat—helping maintain the food chain for aquatic life and enhancing the overall health of estuarine ecosystems that many coastal communities depend on.

A hopeful template for coastal resilience Kerala’s coastal districts increasingly recognise mangroves as nature-based solutions that complement engineering approaches to shoreline protection. Even modest restoration, when sustained, can improve ecosystem services over time—especially in areas where tidal landscapes have become fragmented.

Rajan’s expanding Kannampotti population offers a hopeful template: focused attention on a single threatened species, patient multiplication, and replanting that respects local conditions. Such work can also encourage community conversations around protecting remaining mangrove patches, avoiding damage to young plants, and valuing the role of wetlands in local climate resilience.

**Why it matters:** Conserving rare mangrove species like Kannampotti strengthens biodiversity, supports healthier backwaters and livelihoods, and builds a more resilient coastline—showing how steady, local action can protect India’s natural heritage.
