Mollem National Park, situated in the Dharbandora taluka of South Goa, covers 107 square kilometers of pristine Western Ghats tropical evergreen and moist deciduous forest. Constituting the core zone of the larger 240 km² Bhagwan Mahavir Wildlife Sanctuary, Mollem is Goa's sole national park. Celebrated for the thunderous Dudhsagar Waterfalls (one of India's tallest cascades at 310 meters) and the 12th-century Kadamba temple at Tambdi Surla, the park is an internationally recognized biodiversity hotspot sheltering melanistic leopards (black panthers), king cobras, and herds of Indian gaur.
Location & Geography
Perched on the rugged western slopes of the Sahyadri (Western Ghats) along Goa's eastern frontier with Karnataka, Mollem features dramatic altitudinal variations from 80 meters along the Khandepar River to over 800 meters on the high ridges. Torrential mountain streams sculpt deep rocky canyons, including the famed Devil's Canyon (Devcharacho Gund). The soil is rich laterite and alluvium, nourished by over 4,000 mm of annual monsoon precipitation.
Geographic & Topographic Parameters
Coordinates: 15°22' N, 74°14' E
Elevation Range: 80 m to 800 m above sea level
Terrain & Landscape: Steep Western Ghats escarpments, perennial river valleys, rainforest canyons, and lateritic plateaus
Area & Establishment
Originally known as Mollem Game Sanctuary, the area was declared a Wildlife Sanctuary in 1969 and renamed Bhagwan Mahavir Wildlife Sanctuary. To ensure stricter protection for its core rainforest watershed, a central area of 107 square kilometers was gazetted as Mollem National Park in 1978 under the Wildlife Protection Act, 1972.
Significance
Mollem is part of the Western Ghats UNESCO World Heritage landscape, celebrated as one of the world's eight 'hottest biodiversity hotspots'. It functions as a critical wildlife corridor linking Kali Tiger Reserve and Dandeli Sanctuary in Karnataka to Madei Wildlife Sanctuary in northern Goa, providing unhindered roaming territory for wide-ranging carnivores and wild elephants.
Wildlife
The park hosts an extraordinary diversity of mammalian fauna. Carnivores include the Indian leopard, melanistic leopard (black panther), Royal Bengal tiger, dhole (wild dog), jungle cat, and small Indian civet. Herbivores include the gaur (state animal of Goa), sambar, chital, barking deer, mouse deer, and wild boar.
Flagship Species: Black Panther (Melanistic Leopard) & Gaur
The Black Panther (melanistic Indian leopard, Panthera pardus) is the legendary phantom of Mollem's dense canopies. High humidity and dense canopy shade provide optimal ecological conditions for melanism, allowing these black-coated cats to hunt undetected. Alongside them, massive herds of Indian Gaur (Bos gaurus) can be observed grazing along forest clearings and riverside meadows at dawn.
Avian life is prolific, with over 220 species recorded. Highlights include the ruby-throated yellow bulbul (Goa's state bird), Malabar pied hornbill, fairy bluebird, emerald dove, Malabar trogon, and three-toed kingfisher. Reptiles are exceptional, led by the formidable king cobra, Malabar pit viper, hump-nosed pit viper, and Indian rock python.
Flora & Vegetation
The park's botanical profile transitions from West Coast Tropical Evergreen and Semi-Evergreen forests to Moist Deciduous woodlands. Dominant trees include Terminalia crenulata, Dalbergia latifolia (rosewood), Xylia xylocarpa, and Lagerstroemia lanceolata. Epiphytic orchids, mosses, and lianas create dense hanging gardens in the humid canopy.
Safari & Visiting
The most famous safari excursion is the 4x4 off-road jeep trek from Colem (Kulem) through rushing riverbeds to the base of Dudhsagar Waterfalls. Guided walking safaris lead through ancient rainforest trails to the mysterious Devil's Canyon and the Tambdi Surla waterfalls. Eco-cottages and forest rest houses at Mollem provide comfortable bases for wildlife observation.
