Even though planting this non-native tree species is suggested as a viable strategy to improve adaptiveness of European forests to a more extreme climate and to assure future productivity, the expected temperature increase may induce a decline in forest stand productivity for Douglas-fir in already warm and dry regions.<\/p>\n<p align=\"justify\"><strong>Context<\/strong> Tree species selection is one of the most important forest management decisions to enhance forest productivity and stand stability on a given site. Douglas-fir (<em>Pseudotsuga menziesii<\/em> (Mirb.) Franco var. <em>menziesii<\/em>), a non-native species from north-western America, is seen as an important additional species option for adapting Central European forests to a changing climate.<br \/>\n<strong>Aims<\/strong> This study assesses Douglas-fir forest productivity derived from site conditions. We investigate climatic and physico-chemical soil characteristics and productivity of 28 mature Douglas-fir stands growing on siliceous, as well as carbonate bedrock material in southern Germany and north-eastern Austria.<br \/>\n<strong>Methods<\/strong> The importance of climatic and physico-chemical soil characteristics was analyzed with the machine learning method Random Forests.<br \/>\n<strong>Results<\/strong> The results show that Douglas-fir growth correlates with climate, soil moisture, and soil nutrient availability derived from ten climatic and physico-chemical soil parameters.<br \/>\n<strong>Conclusion<\/strong> The broad pH optimum between 4.5 and 7.2 reflects the broad physiological amplitude of Douglas-fir, and no significant differences were detectable between carbonate and siliceous bedrock. We also conclude that climate change may induce a forest stand productivity decline, because lower productivity with the highest mean summer temperature across our study range was observed at the warmest sites in Eastern Austria.<\/p>\n<p><strong>Keywords<\/strong><br \/>\nNon-native tree species, Climate change adaptation, Site conditions, Site index<\/p>\n<div class='altmetric-embed' data-badge-type='donut' data-doi='10.1007\/s13595-019-0805-3'  style='float: right; ' ><\/div>\n<p><strong>Open access publication<\/strong><br \/>\nEckhart, T., P\u00f6tzelsberger, E., Koeck, R. et al.
