Regeneration establishment and juvenile tree height growth are important to ensure sustainability within forest stands. In this chapter, we demonstrate how routine inventory data may be used to assess the probability of regeneration within the last 5 years, the species composition and the regeneration density within pure and mixed as well as even and uneven-aged forests. We also propose an approach for predicting juvenile tree height growth and mortality. Finally, we demonstrate the applicability of our regeneration models using independent data sets, which were not used for model calibration. The results of the study suggest that our regeneration assessment routines and the height growth predictions were unbiased and exhibited consistent results. The equations are simple and require only routine inventory data and can be easily adapted to any other forest type if regeneration data are available.
