%description
The Clutter model is a significant forest growth simulation tool. Grounded
on individual trees and comprehensively considering factors such as
competition among trees and the impact of environmental elements on
growth, it can accurately reflect the growth process of forest stands. It
can be applied in areas like forest resource management, harvesting
planning, and ecological research. With the help of the Clutter model,
people can better understand the dynamic changes of forests and provide a
scientific basis for rational forest management and protecting the
ecological environment. This R package can effectively realize the
construction of forest growth and harvest models based on the Clutter
model and achieve optimized forest management.References: Farias A, Soares
