One of target regions of a worldwide network GLORIA (Global Observation Research Initiative in Alpine Environments) has been installed in the Katunskiy Biosphere Reserve (Central Altai) for revealing influence of climate changes on the plant diversity of alpine ecosystems during recent decades. The target region consists of 4 mountain summits selected according to the altitudinal gradient from the subalpine to the upper part of the alpine ecotone (2181, 2231, 2358, 2475 m.a.s.l.). Between 2005 and 2015, species in the target region shifted their distributions to higher altitudes by 5.3 м on average. Plant species richness increased on three higher summits and decreased on the lower summit.
