Biome: Tropical and Subtropical Coniferous Forests... Size: 3,700 square miles... Conservation Status: Critical/Endangered..... Introduction: "The Northeast India-Myanmar Pine Forests [IM0303] ecoregion is one of only four tropical or subtropical conifer forest ecoregions in the Indo-Pacific region. All of these ecoregions contain less biodiversity than the forests that surround them. However, they contain processes and species unique to these ecosystems. This ecoregion contains moderate levels of biodiversity but remains largely intact, providing opportunities to conserve and protect this ecoregion?s biodiversity into the future. Description Location and General Description These forests are found in the north-south Burmese-Java Arc. The Arc is formed by the parallel folded mountain ranges that culminate in the Himalayas in the north. Moving south are the mountain ranges of Patkoi, Lushai Hills, Naga Hills, Manipur, and the Chin Hills. The outer southwestern fringe of mountain ranges forming the Arc is the Arakan Yomas, the southern continuation of the folded mountain ranges branching off from the Himalayas. Geologically the ecoregion has gley and black slates. Dark-colored serpentine and gabbro also are found interstratified within the shales..."
