%description
Climate-sensitive, single-tree forest simulator based on data-driven
machine learning. It simulates the main forest processes— radial growth,
height growth, mortality, crown recession, regeneration, and harvesting—so
users can assess stand development under climate and management scenarios.
The height model is described by Skudnik and Jevšenak (2022)
<doi:10.1016/j.foreco.2022.120017>, the basal-area increment model by
Jevšenak and Skudnik (2021) <doi:10.1016/j.foreco.2020.118601>, and an
overview of the MLFS package, workflow, and applications is provided by
Jevšenak, Arnič, Krajnc, and Skudnik (2023), Ecological Informatics
<doi:10.1016/j.ecoinf.2023.102115>.
