MLFS (version 0.4.2)

Machine Learning Forest Simulator

Description

Climate-sensitive forest simulator based on the principles of machine learning. It stimulates all key processes in the forest: radial growth, height growth, mortality, crown recession, regeneration and harvesting. The method for predicting tree heights was described by Skudnik and Jevšenak (2022) , while the method for predicting basal area increments (BAI) was described by Jevšenak and Skudnik (2021) .
