• Characteristics of SPS in Northeast State of Pará:Characteristics of SPS in Northeast State of Pará:
– TemporaryTemporary
– Grazing in tree plantationsGrazing in tree plantations
– Main trees: paricá (Main trees: paricá (Schizolobium amazonicumSchizolobium amazonicum Huber ex. Huber ex. Ducke) and teak (Ducke) and teak (Tectona grandisTectona grandis L.f.) L.f.)

OBJECTIVESOBJECTIVES
• Analyze the economic viability of SPSs Analyze the economic viability of SPSs
with teak established in farm areas, with teak established in farm areas,
comparing it to traditional tree plantations comparing it to traditional tree plantations

CONCLUSIONSCONCLUSIONS
• In the case of teak tree, the SPS is economically more In the case of teak tree, the SPS is economically more
attractive than the TTP. attractive than the TTP.
• The adoption of silvopastoral systems in the Northeast The adoption of silvopastoral systems in the Northeast
Pará State should be encouraged as an activity over Pará State should be encouraged as an activity over
