Site description The Pangolakha Range, extending below the Chola Range, separates Sikkim from Bhutan. Hathichirey (the place where elephants can penetrate) forms the tri-junction between Bhutan, Sikkim and West Bengal where further down the forest continues as the Neora Valley National Park (an IBA in West Bengal). The Sanctuary has typical alpine-temperate-subtropical vegetation with high altitude lakes around Jelep La. Rhododendron, Silver Fir, Juniper forest and associated ground flora, moss-filled oak forests with dense bamboo thickets form ideal habitat for the Red Panda Ailurus fulgens, the State Animal.
