A first biomeridian will be established off the Mt Everest massif. In Nepal’s Makalu-Barun National Park, the Barun Valley is intact from biological tropics to its arctic-like summits (Everest, but also Lhotse 4th highest and Makalu 5th highest). Few resident life forms are above 16,000 feet, while the valley bottom contains a rich biology with tropical species such as tree ferns. There are no villages in this valley, and only three very simple trails. Insofar as any place in the Himalaya is pure wild , the Barun is that place. Here, a partnership of local people and scientists from around the world set up the first biomeridian in the winter of 2017-2018. The methods are still being worked out, more sensors and cameras are steadily being added. Protected as the core of Nepal’s Makalu-Barun National Park, it still holds its natural balances. At the top are no resident life forms; further down are lichens, spiders, then plants and animals. This one valley system encompasses the wild diversity of Asia; it has, for example, all three species of leopard: common spotted, the exotic snow leopard, and the rare clouded leopard. Land quadrant monitoring stations have been designated up the valley where all species in that quadrant are visually identified. At each station, in addition to visual monitoring is also audio with recorders with enhanced microphones that monitor birds and insects not only during the day but also the night, and through the cycle of 365 days of the year. Importantly, north of the Barun Valley and parallel to it, also falling off Everest-Lhotse-Makalu, is a valley with drier biomes. In China’s Tibet is the Gama Valley, also pristine, with its valley bottom in the warm temperate zone extending up to the arctic. The Mount Everest biomeridian project will install monitoring stations through both valleys, one in Nepal and the second in China.
