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 north east, the Eravikulam National Park and Anamudi Shola National Park to the north, the Pampadum Shola National Park to the south and the proposed Palani Hills National Park to the east.
These protected areas are especially known for several threatened and endemic species including Nilgiri Thar, the grizzled giant squirrel, the Nilgiri wood-pigeon, elephant, the gaur, the Nilgiri langur, the sambar, and the neelakurinji (that blossoms only once in twelve years).
There has been action to address the problems of property takeovers by the land mafia that have, according to successive governments, plagued the area. In 2011, the government estimated that 20,000 hectares of land had been illegally appropriated and it launched a campaign of evictions that had first been mooted in 2007.Eravikulam National Park
