Long-term provenance trials allow assessing climate-growth relationships of different genotypes of a tree species. This knowledge is crucial in efforts to mitigate impacts of climate change on forest ecosystems. This project is taking advantage of a unique opportunity to study climate growth relations based on destructive whole-tree analysis in provenance trials of Lodgepole pine (Pinus contorta Dougl. ex. Loud.). By combining annual height increment, radial growth, intra-annual high resolution wood density and carbon isotope profiles, this approach will allow for a comprehensive assessment of climate change impacts on carbon sequestration, wood production and wood characteristics. It as well will allow identifying resilient and productive genotypes for reforestation in a changing climate.

长期的种源试验可以评估一个树种不同基因型的气候-生长关系。这种知识对于减轻气候变化对森林生态系统的影响至关重要。该项目是利用一个独特的机会，研究气候生长关系的破坏性全树分析的基础上，在种源试验的黑松（松contorta Dougl。ex.大声说。）。通过结合年度高度增量、径向生长、年度内高分辨率木材密度和碳同位素分布图，这一方法将能够全面评估气候变化对碳固存、木材生产和木材特性的影响。它还将允许在不断变化的气候中确定恢复力和生产力的基因型。
