Grounded on individual trees and\ncomprehensively considering factors such as competition among\ntrees and the impact of environmental elements on growth, it\ncan accurately reflect the growth process of forest stands. It\ncan be applied in areas like forest resource management,\nharvesting planning, and ecological research. With the help of\nthe Clutter model, people can better understand the dynamic\nchanges of forests and provide a scientific basis for rational\nforest management and protecting the ecological environment.\nThis R package can effectively realize the construction of\nforest growth and harvest models based on the Clutter model and\nachieve optimized forest management.References: Farias
