Short summary

In shade-tolerant tree species, growth is not strictly related to tree age. In this study we show that novel tree ring standardization models that incorporate tree size in the year of ring formation produce more accurate chronologies than those produced by contemporary, age-based standardization models. These findings are important for accurate and reliable long-term trend reconstruction in tree ring studies in all species but are especially so for shade-tolerant species.
