JapanFlux2024 MN-Udg Udleg practice forest

The larch forests on the permafrost in northeastern Mongolia are located at the southern limit of the Siberian taiga forest, which is one of the key regions for evaluating climate change effects and responses of the forest to climate change. We conducted long-term monitoring of seasonal and interannual variations in hydrometeorological elements, energy, and carbon exchange in a larchforest in northeastern Mongolia from 2010 to 2012. Long-term monitoring of the energy and carbon balances and hydrometeorological elements and phenological camera monitoring have been carried out at the Udleg Forest Research Station (UFRS) of the National University of Mongolia (NUM), Batsumber district, Tov province using a 25-m tall tower over a larch forest on the permafrost area of northern Mongolia since January 2010. The UFRS is located 50 km north of Ulaanbaatar, the capital city of Mongolia. Fences protect 2 ha of the forest around the tower from grazing and illegal logging. Large forest fires occurred near the UFRS in 1968, 1996, and 2005 (Otoda et al., 2012).
