India's 101st Ramsar Site: What's Special About Arunachal Pradesh's Glaw Lake

A freshwater lake tucked inside a tiger reserve in the Eastern Himalayas has just given Arunachal Pradesh something it never had before: a wetland recognised by the world. On 3 August 2026, Union Environment Minister Bhupender Yadav announced that Glaw Lake had been designated India's 101st Ramsar Site - and the state's first.

The news arrived in a social media post from Yadav, who called it a milestone for biodiversity, water and climate security, and sustainable livelihoods. It also marked a symbolic moment for India's wetland conservation programme, which has grown from a modest starting point to a three-figure tally in little over a decade. "India continues Her journey beyond a century in designating Ramsar Sites," Yadav wrote, as the country's Ramsar network officially crossed the 100 mark.

A Lake Inside A Tiger's Territory

Glaw Lake sits within the Kamlang Tiger Reserve and Wildlife Sanctuary, a 783 sq km protected area in the Lohit district of Arunachal Pradesh, near the town of Wakro. It's a landscape few outsiders associate with lakes at all - Kamlang is better known as India's 50th tiger reserve, home to the Bengal tiger, leopard and clouded leopard, spread across tropical and sub-tropical forest close to the Myanmar border.

Yadav described Glaw Lake as a pristine freshwater lake in the Eastern Himalayas and a biodiversity hotspot, fed by perennial mountain streams. That detail matters more than it sounds. A lake fed by year-round mountain streams, rather than seasonal rain alone, tends to hold its water table steady through the dry months - which is exactly what makes it valuable both as a wildlife refuge and as a water source for communities living around the reserve.

The Mishmi, Digaro Mishmi and Miju Mishmi tribal communities live along the periphery of the sanctuary, and their presence is part of why the site's new status carries more than ecological weight - Ramsar recognition typically comes with a stronger case for conservation funding and community-based management.

The Numbers Behind The "Biodiversity Hotspot" Label

Tags like "biodiversity hotspot" get used loosely in conservation news, but the numbers behind Glaw Lake back it up. The site and its surrounding catchment have more than 150 tree species and 49 orchid species recorded, an unusually dense concentration for a single wetland catchment, and one that points to the layered forest cover typical of undisturbed Eastern Himalayan terrain.

Yadav called the state's first Ramsar tag a significant milestone for Arunachal Pradesh specifically, and the framing is fair: until this announcement, the state, despite sitting inside one of the most biodiverse stretches of the Himalayas, had no wetland on the Ramsar list at all.

Why The 101 Number Actually Matters

Glaw Lake's designation isn't just about one lake. It's the marker that pushed India's Ramsar count past the century mark, and the trajectory behind that number is the real story. Yadav pointed out that India had just 26 Ramsar Sites in 2014, a figure that has since nearly quadrupled. Ramsar status is granted under the international Ramsar Convention on Wetlands, and it obliges signatory countries to conserve and sustainably use the sites on the list - not just name them.

For context, the pace of designations has been steady rather than sudden: Bihar's Gogabeel Lake became that state's sixth Ramsar site only recently, and Tamil Nadu currently holds the highest count of any Indian state. Arunachal Pradesh, by contrast, was starting from zero - which is part of why Glaw Lake's entry feels disproportionately significant for the state, even if it's a single addition to a national list of 101.

What Ramsar Status Changes

A Ramsar tag doesn't fence off a lake or halt activity around it. What it does is bind the site to international reporting standards, open it up to conservation funding tied to wetland management, and give local and state authorities a clearer mandate to protect the catchment from encroachment or unregulated development. For a site like Glaw Lake, sitting inside an already-protected tiger reserve, the designation layers wetland-specific safeguards - water quality, catchment vegetation, fish and amphibian habitat - on top of the wildlife protections that already existed.
