摘要: The role of isolated mountain forests in Central Asian drylands has been the subject a number recent studies. present paper examines islands birch and willow forest Mongolian Govi Altay Mountains. Using vegetation surveys, dendrochronological studies charcoal findings, it is attempted to assess present-day ecological state as well environmental history trends. One three studied seems be expanding rapidly due declining levels utilization under climatically favourable conditions. other however, situated about 350 km south-east former, are threatened by consistently high anthropogenic pressure. Based on evidence, islands’ witnesses once coherent belt that may have retreating since mid-Holocene discussed.
