SisILPF_Elliottii software is a simulator that can support management activities, economic analysis, and planning for Pinus elliottii as the forest component in integrated crop-livestock-forest systems. This technological tool can be used to test all the management options for Pinus elliottii as a component of integrated crop-livestock-forest systems for different climates and soil conditions, forecast wood production in the present and in future conditions, conduct economic analyses, and decide on the best alternative for managing plantations. 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 the trees and the CO2 and methane, and generates graphs estimating the number of animals whose methane emissions can be compensated by the trees in the integrated system.
