Introduction Pinus koraiensis is a dominant tree species in northeastern China. Estimating
its biomass is required for forest carbon stock monitoring and accounting. Methods This …

Accurate large-scale biomass prediction is crucial for assessing forest carbon storage and
dynamics. It can also inform sustainable forest management practices and climate change …

Crown width is one of the most important crown dimensions that influence tree growth and
survival. Accurate crown width prediction is vital for forest management. However …

Most of the forest biomass models that have been developed so far focus on the study of the
