Bioclimatic framework models for forest tree species provenances

The paper highlights issues of key tree species adaptation to climatic conditions. It issuggested that climatic fac-tor simpact genetic division of aspecies in to ecotypes [1] according to the site climatic conditions and developmentof genetically various population provenances with features favour able for adaptation to certain climatic conditionsfor instance colder or drier climate. Provenance geographical distributionis specified with bioclimatic frameworkmodels [2]. Theauthors shaped bioclimatic frame work models for provenances of Common oak, Norway spruce, Siberianspruce, Ajan spruce, Scots pine, Siberian stone pine, Sukachev larch and Siberian larch. The offered provenanceframework models divide Russian territory into climatopes – areas presumably with relatively uniform habitat bio-climatic factors. In author's opinion provenence framework models are needed to specify adverse impacts of climatechange on forest management which is critical for development of forest management adaptation strategy to esti-mated global climate change [3].
