Kaziranga National Park is a protected area in the northeast Indian state of Assam. Spread across the floodplains of the Brahmaputra River, its forests, wetlands and grasslands are home to tigers, elephants and the world’s largest population of Indian one-horned rhinoceroses. Ganges River dolphins swim in the park’s waters. It’s visited by many rare migratory birds, and gray pelicans roost near Kaziranga village.

All those who have thought Indian one-horned rhinoceros only existed in Jurassic-era, then a trip to Kaziranga is a must for them. One of the most sought after wildlife holiday destinations in India, Kaziranga National park’s 430 square kilometer area sprinkled with elephant-grass meadows, swampy lagoons, and dense forests is home to more than 2200 Indian one-horned rhinoceros, approximately 2/3rd of their total world population

The vast expanse of tall elephant grass, marshland, and dense tropical moist broadleaf forests undoubtedly makes the park look beautiful but it’s the presence of Brahmaputra river, which makes it look enigmatic.

The Hollongapar Gibbon Sanctuary, formerly known as the Gibbon Wildlife Sanctuary or Hollongapar Reserved Forest is an isolated protected area of evergreen forest located in Assam, India. The sanctuary was officially constituted and renamed in 1997. Set aside initially in 1881, its forests used to extend to the foothills of the Patkai mountain range.

Since then, the forest has been fragmented and surrounded by tea gardens and small villages. In the early 1900s, artificial regeneration was used to a develop well-stocked forest, resulting in the site's rich biodiversity. The Hollongapar Gibbon Sanctuary contains India's only gibbons – the hoolock gibbons, and Northeastern India's only nocturnal primate – the Bengal slow loris.

The upper canopy of the forest is dominated by the hollong tree (Dipterocarpus macrocarpus), while the nahar (Mesua ferrea) dominates the middle canopy. The lower canopy consists of evergreen shrubs and herbs. The habitat is threatened by illegal logging, encroachment of human settlements, and habitat fragmentation.
