The selection of nemoral and taiga group among of a moth and butterflies (Lepidoptera) species for monitoring in Chernevaya taiga of the Ulan-Burgasy mountain-range

In the last twenty years new nemoral species of Lepidoptera for the territory of Western Transbaikalia were found. Such expansion of nemoral species ranges is associated with climate change. Thus we organized monitoring of such species in the Western Transbaikalia. During the works the optimal places for the existence of nemoral species in the western part of Transbaikalia were found. It is so called «chernevaya taiga» or «chern» that consist of such trees-edifiers as fir (Abies sibirica Ledeb.) and alsou aspen (Populus tremula L.). Сhernevaya taiga it is refuges of broadleaf elements of flora and fauna for the South Siberia and is located on warm and wet slopes of the Western Transbaikalia mountains. Chern' has been found during our field works 2012-2016 at 900-1100 meters heights in the southwestern part of the Ulan-Bourgasy ridge. Some later in this places had been discovered taiga species of lepidoptera which becoming rare or don't going at all east of Ulan-Burgasy. It is another indicators group of climate change in region. The annotated list of founded species-indicators in chernevaya taiga of the Ulan-Bourgas range is given in this paper.
