New Amarambalam Reserved Forest, Protected forest area in Malappuram District, Kerala, India

New Amarambalam Reserved Forest is a protected area in Malappuram District, Kerala, covering a range of terrain from lowland forest to high mountain ridges along the Western Ghats. The land moves through several vegetation zones, from dense tropical forest to montane woodland, all within a single continuous stretch of protected land.

The sources record no founding date for the reserve; it is administered as part of Karimpuzha Wildlife Sanctuary in Kerala and adjoins Silent Valley National Park, continuing into the Nilgiri Biosphere Reserve. Its bird life was surveyed in the 1990s and 2000s: P. O. Nameer of Kerala Agricultural University reported 11 woodpecker and 11 flycatcher species in 2003, and by 2004 ten IBA trigger species were listed.

The forest is part of the Karimpuzha Wildlife Sanctuary and the Nilgiri Biosphere Reserve, and the Indian Bird Conservation Network has recorded 212 bird species in the Nilambur and Karimpuzha forests. In 2003 P. O. Nameer of Kerala Agricultural University reported 11 woodpecker, 11 flycatcher, nine babbler, seven bulbul and three barbet species here. Ten IBA trigger species were counted as of 2004, among them the lesser adjutant, white-rumped vulture and Nilgiri wood-pigeon.

The reserve lies in Malappuram District, with its southern edge meeting Silent Valley National Park in Palakkad District and its northern limit at Nadugani in the Nilgiris of Tamil Nadu. It is administered as part of Karimpuzha Wildlife Sanctuary. The terrain climbs from 40 m to 2,554 m, so expect heavy rain and dense cover; the highest bird species richness was recorded in November and the highest diversity index in April.

The forest borders the Nilambur Valley, which is known for having some of the oldest teak plantations in the world, and in places you can see the sharp line where planted teak gives way to wild forest. This contrast makes the transition between managed land and protected forest unusually visible to anyone walking the area.
