The Chaco region is a vast plain extending over northwestern Argentina, Bolivia and Paraguay. Over the years, the woody component has increased in all vegetation communities of the Chaco. This poses a major problem for grassland productivity because the woody plants compete for resources with grass, impact advanced tree regeneration, hamper livestock and personnel movements, and restrict accessibility for forage due to high stem density and thorns. These disadvantages far outweigh the advantages offered by such trees and shrubs in terms of providing shade, foliage and fruits, and improving soil conditions. To address this issue, a silvopastoral system called ?Low intensity roller-chopping? (RBI) was tried, based on theoretical approaches and fi eld research, in the western Chaco from 1990 to 2014. A distinctive feature of the system is that trees that are already present in the Chaco system are mechanically disturbed by properly adjusting the size of the tractor and the roller-chopper and regulating the frequency and severity of the number of passes over the standing vegetation. | |
