Munnar was the summer resort of the British Government in the south. The town is situated at the convergence of three mountain streams, namely Muthirappuzha, Nallathanni, and Kundala. Munnar has some of the largest tea plantations in the world. This hill station, which is more than 5,000 feet above sea level, is a tourist attraction noted for its scenic landscapes. Most of the native flora and fauna of Munnar have disappeared due to severe habitat fragmentation resultant from the creation of the plantations. However, some species continue to survive and thrive in several protected areas nearby, including the new Kurinjimala Sanctuary to the east, the Chinnar Wildlife Sanctuary, Manjampatti Valley, and the Amaravati reserve forest of Indira Gandhi Wildlife Sanctuary to the northeast, the Eravikulam National Park and Anamudi Shola National Park in the north, and the Pampadum Shola National Park to the south. The Palani Hills National Park is proposed to come up to the east of Idukki. These protected areas are especially known for several threatened and endemic species including the Nilgiri tahr, the grizzled giant squirrel, the Nilgiri wood-pigeon, the elephant, the gaur, the Nilgiri langur, the sambar, and the neelakurinji (that blossoms only once in twelve years).
