snowfall is experienced in higher altitudes. Temperature varies from 4.2 °C to 17.7 °C at altitudes ranging from 2,200 m onwards. Biology and ecology The area around Mouling National park is one of great bio-diversity, with a juxtaposition of different biotopes, and is often called the state's cradle of biodiversity. With elevations ranging from 400 m to over 3000 m in the park, it forms a transition zone between tropical forests at lower altitudes to most temperate forest at altitudes above 2800 m. The overall inaccessibility due to poor or no roads and stories associated with the forest itself have kept the core area of the national park relatively untouched by human activities. There has been evidence of past practices of jhum cultivation, especially in the Northern and South-eastern areas of the park. Animals such as the takin, goral, Indian leopard, Bengal tiger, barking deer, serow and red panda are living there.
