SisILPF_Cedro software performs simulations to support management activities, economic analysis, and planning for Toona ciliata as the forest component in integrated crop-livestock-forest systems. This technological tool can be used to simulate all the management options for Australian red cedar as a component of integrated crop-livestock-forest systems for different climates and soils, forecast wood production in the present and in future conditions, conduct economic analyses, and decide on the best alternative for managing plantations. The program generates wood assortment tables by classes of industrial uses such as laminates, sawmilling, and energy, primarily as a function of the log diameters and lengths indicated by the user. By quantifying the amount of wood produced by type of industrial use, producers can manage their forests to produce wood directed toward the most profitable use. Additionally, the software calculates the carbon captured by trees and the equivalent in CO2 and methane, and generates graphs estimating the number of animals whose methane emissions can be compensated by the trees in the integrated system.
