Kaziranga National Park or Tiger Reserve:
Kaziranga National Park, located in Assam, is renowned for its conservation of the great one-horned rhinoceros and rich biodiversity.
Contains about two-thirds of the world’s great one-horned rhinoceros population—over 2,400 individuals as of recent counts.
Designated as a UNESCO World Heritage Site in 1985 due to its unique natural environment and successful wildlife conservation.
Declared a tiger reserve in 2006 and has one of the highest densities of tigers in the world, alongside elephants, wild water buffalo, and swamp deer.
Established as a reserve forest in 1905 and became a national park officially in 1974; it has expanded from its original area of 232 sq km to about 430 sq km.
The terrain includes marshes, tall elephant grass, tropical forests, and riverine habitats formed by major rivers like the Brahmaputra.
Recognized as an Important Bird Area, hosting migratory birdslike lesser white-fronted goose, ferruginous duck, and various stork species.
Home to 35+ mammal species, including endangered and threatened species like Bengal tigers, elephants, leopards, and eastern swamp deer.

Least Concern
Size: Tiger is largest; snow leopard is smallest among these seven.
Range: Africa (lion, leopard, cheetah); Asia (tiger, leopard, snow leopard, cheetah reintroduction); Americas (jaguar, cougar).
Social behavior: Only lions form prides; others are solitary.
Adaptations: Cheetahs are built for speed; jaguars for power; snow leopards for cold/altitude
All of them use scent marking to mark their territories.
Steps for Conservation:
International big cat alliance (IBCA):
The IBCA was launched by the Prime Minister Shri Narendra Modi on 9th April,2023, during the event ‘Commemorating 50 years of Project Tiger’.
IBCA headquarters in India
It was launched with the aim of conservation of seven big cats – Tiger, Lion, Leopard, Snow Leopard, Cheetah, Jaguar and Puma – with membership of all UN countries/the range countries harbouring the said species and non-range countries where historically these species are not found but interested to support big cat conservation.
The IBCA was established by Government of India, through the nodal organisation viz., National Tiger Conservation Authority (NTCA), Ministry of Environment, Forest & Climate Change (MoEFCC).
About TX2:
It was clear that business-as-usual approaches were not working when wild tiger populations did not stop declining despite conservation efforts.
The global tiger population hit an all-time low; there were only around 3,200 left in the wild by 2010.
In light of this critical situation, the governments of all 13 tiger range countries came together for the first time at the St Petersburg Tiger Summit during the same year.
There, they committed to the most ambitious conservation goal ever set for a single species – to double the number of wild tigers by 2022, the next Chinese Year of the Tiger.
