Answer : 1. "Arunachal Pradesh"
Explanation :

During the Republic Day parade, Arunachal Pradesh highlighted its Singchung Bugun Village Community Reserve, a 17-square-kilometre biodiversity hotspot near the Eaglenest Wildlife Sanctuary. Established in 2017, the reserve protects the Bugun leocichla, a critically endangered passerine bird, named after the Bugun community. The Buguns, an indigenous group of approximately 2,000 people, inhabit 12 villages adjacent to Eaglenest. Community reserves, introduced in India's Wildlife Protection Act, act as important buffers, connectors and migration corridors between national parks and forests, thereby ensuring biodiversity conservation.
