abstract = "While functional diversity (FD) has been shown to be positively related to a number of ecosystem functions including biomass production, it may have a much less pronounced effect than that of environmental factors or species-specific properties. Leaf and wood traits can be considered particularly relevant to tree growth, as they reflect a trade-off between resources invested into growth and persistence. Our study focussed on the degree to which early forest growth was driven by FD, the environment (11 variables characterizing abiotic habitat conditions), and community-weighted mean (CWM) values of species traits in the context of a large-scale tree diversity experiment (BEF-China). Growth rates of trees with respect to crown diameter were aggregated across 231 plots (hosting between one and 23 tree species) and related to environmental variables, FD, and CWM, the latter two of which were based on 41 plant functional traits. The effects of each of the three predictor groups were analyzed separately by mixed model optimization and jointly by variance partitioning. Numerous single traits predicted plot-level tree growth, both in the models based on CWMs and FD, but none of the environmental variables was able to predict tree growth. In the best models, environment and FD explained only 4 and 31% of variation in crown growth rates, respectively, while CWM trait values explained 42%. In total, the best models accounted for 51% of crown growth. The marginal role of the selected environmental variables was unexpected, given the high topographic heterogeneity and large size of the experiment, as was the significant impact of FD, demonstrating that positive diversity effects already occur during the early stages in tree plantations. The manuscript addresses an approach to the framework suggested by D{\'i}az et al. (2007, PNAS) to disentangle the effect of environment, species identity and functional diversity in tree communities. We present a dataset with 231 plots varying in ecological characteristics, species and functional diversity. We used a set of 41 plant functional traits for 23 tree species. Our most striking result is that the ecological environment only explained 4% of plot mean values in crown increment, whereas community weighted mean values and functional diversities of trait combinations explained 42 and 31%, respectively, adding up to 51% explained variation in combination. We can conclude that functional diversity even 3 years after planting has a significant impact on productivity.",
