The main cause of loss of natural resources in Central America is the advance of the agricultural border (UICN, 2001),
demanding more land area to produce the same amount of food, as a consequence of the loss of the productive capacity
of the ground and the decrease sources (García 2003), the traditional farming practices as crop in the zones of greater
slopes, exaggerated use of agrochemical substances and overpasturing have caused negative impacts on the ecosystems
At the moment livestock is one of the activities of production that have the biggest share of the regions economy (ILRI, 2004),
although at the same time it has been announced one of the main causes of the natural ecosystems transformation, provocing the
loss of the agrosystems sustainability (Kaimowitz 1996). Taking into account that the systems of extensive production are coming
along with the degradation of natural ressources that exist in the forest, an approach of new technics, that are compatible with
livestock production and the conservation of natural ressources become necessary. One of these approaches is the introduction
of Silvopastoral technologies (Ibrahim et al. 1999).
SilvoPastoral Systems (SPS) constitute an alternative for cattle production, where wooded perennial (trees and/or shrubs)
interact with the traditional components (herbaceous covers and animals) under a system of integral handling (Ibrahim, 1996).
This is a system of sustainable production that, through transformations that improve the performance in production, generates
environmental services when protecting and conserving the sources (Ibrahim et al. 2003).
