The Ecological Crown of Garo Hills: UNESCO Global Recognition

Crowning the rugged, cloud-mantled spine of the Garo Hills across the intersection of West, East, and South Garo Hills districts, the Nokrek Biosphere Reserve represents one of the most ecologically vital and pristine biodiversity strongholds on the planet. Encompassing a core national park area of roughly 47 square kilometres within a wider 820-square-kilometre biosphere reserve, Nokrek was formally inscribed into the UNESCO World Network of Biosphere Reserves in May 2009, cementing its status as an international ecological treasure.

The apex of the reserve is Nokrek Peak, which rises to a commanding elevation of 1,412 meters (4,633 feet) above sea level, making it the highest mountain summit in the entire Garo Hills range. Draped in continuous, virgin subtropical broadleaf rainforest that has remained largely untouched by commercial exploitation for centuries, Nokrek acts as a vital hydrological sponge and watershed that feeds five major river systems—including the Ganol, Dareng, and Simsang rivers—providing life-giving water to hundreds of downstream tribal communities.

📋 UNESCO World Biosphere & Global Citrus Gene Sanctuary

Added to the UNESCO World Network of Biosphere Reserves in 2009, Nokrek is the primary global gene sanctuary for *Citrus indica* (the wild Indian orange), the ancestral genetic progenitor of all domestic citrus fruits. The reserve is also a crucial stronghold for the endangered Western Hoolock Gibbon (*Hoolock hoolock*), India's only ape species.

The Mother of All Oranges: The Citrus Indica Gene Sanctuary

What grants Nokrek extraordinary international scientific importance is its role as the world's primary living gene sanctuary for *Citrus indica*, known in the indigenous Garo language as *Mē·mang narang* (meaning 'the fruit of the spirits' or 'ghost orange'). Botanical geneticists have established that this rare, endangered wild citrus species is the ancestral progenitor and evolutionary mother of all cultivated commercial citrus fruits on Earth—including modern sweet oranges, mandarins, lemons, and grapefruits.

Discovered flourishing in the wild rainforest understory of Nokrek, *Citrus indica* produces small, intensely aromatic, bitter-sour fruits packed with genetic resistance to lethal citrus viruses, root rot, and pest infestations. To safeguard this priceless botanical genetic reservoir against extinction, the Government of India established a specialized Citrus Gene Sanctuary within Nokrek. Walking through the reserve with knowledgeable Garo forest trackers reveals these venerable wild citrus trees growing naturally alongside wild coffee plants, giant wild bananas, and rare medicinal herbs.

Faunal Wonders: Hoolock Gibbons, Red Pandas, and Clouded Leopards

The dense, multi-canopy rainforests of Nokrek harbor an astonishing assemblage of rare and endangered mammalian species. Foremost among them is the Western Hoolock Gibbon (*Hoolock hoolock*), India's sole indigenous ape species. The canopy of Nokrek is alive with the enchanting, melodious territorial calls of gibbon family pairs echoing across the misty valleys at dawn. Observing these acrobatic primates swinging effortlessly through forty-meter-high tree branches using their elongated arms is a wildlife encounter of the highest order.

Nokrek is also one of the rare subtropical reserves where the endangered Red Panda (*Ailurus fulgens*) has been recorded inhabiting high-elevation bamboo stands. The park supports healthy populations of Asian elephants, clouded leopards, marbled cats, Asian golden cats, binturongs (bearcats), and the elusive stump-tailed macaque. Birdlife is equally spectacular, featuring great Indian hornbills, Rufous-necked hornbills, and vibrant pheasants that flash through the emerald canopy.

⚠️ Strict Forest Department Entry Permits & Wild Elephant Corridors

Entering the core zone of Nokrek National Park requires a formal permit from the Divisional Forest Officer (DFO) Wildlife at Tura and mandatory accompaniment by certified Garo wildlife trackers. The reserve is an active migratory corridor for wild Asian elephants; never hike after dusk, avoid wearing strong perfumes, and obey forest guard safety directives.

The Summit Expedition: Trekking to the 1,412-Metre Apex

For adventurous trekkers, ascending to the summit of Nokrek Peak is an unforgettable wilderness journey. The classic trek begins from the picturesque Garo roadhead hamlet of Daribokgre, situated roughly thirty-five kilometres from Tura. From the forest checkpost, hikers follow a lush, undulating single-track footpath that ascends approximately 4.5 kilometres through dense primary jungle to the summit watchtower.

The trail winds beneath gigantic forest trees draped in thick mosses, rare epiphytic orchids, and hanging pitcher plants, crossing crystal-clear mountain streams where water can be drunk directly from the source. The ascent takes between two and two-and-a-half hours at a steady pace. Upon reaching the summit watchtower at 1,412 meters, hikers step above the forest canopy to witness a magnificent 360-degree panorama: rolling green mountain ranges stretch to the horizon in every direction, blanketed in billowing white cloud banks and sun-dappled rainforest folds.

Travel Logistics, Daribokgre Basecamp, and Visiting Tips

Visiting Nokrek requires securing an entry permit from the Meghalaya Forest Department at Tura, where certified wildlife guides are assigned. From Tura, the journey to the basecamp at Daribokgre takes about 1.5 to 2 hours by four-wheel-drive vehicle along scenic mountain roads winding through betel nut plantations and indigenous Garo villages.

The village of Daribokgre offers excellent community-run eco-lodges and traditional bamboo homestays where travelers can experience the warm hospitality of the A'chik people. The optimal trekking and wildlife viewing season spans from October through May. During these months, the weather is pleasantly cool, trails are dry, and gibbon activity is high. Visitors should pack high-ankle trekking boots, leech socks, binoculars for birdwatching, a headlamp, and a lightweight rain shell.
