Geocentric alternatives to site index for modeling tree increment in uneven-aged mixed stands

Our results indicate that without rigorous testing, tried-and-trusted decision tools developed for even-aged, single-species stands cannot be transferred to uneven-aged mixed forests. Precipitation- and temperature-based variables provide dynamic proxies which may allow us to better grasp the complexity of climate-growth relationships. This understanding is essential for reducing the uncertainty around predictions of climate change impacts on forest ecosystems.
