The Chaco region, faces land cover changes due to agricultural and cattle ranching intensification. Silvopastoral practices employ roller chopping, in which the shrub layer is completely removed. Disturbance triggers vegetation successional processes and promotes shrub recolonization. Roller chopping only removes aerial organs, so some species resprout, which can modify their architecture. Searching for sustainable alternatives, participative approaches introduced “deschampado”, which involves a low-intensity intervention, and sowing shade-tolerant fodder grasses. The study aims to compare roller chopping and deschampado, regarding the changes in cover, composition and architecture of the shrub layer, and the variations in the light environment produced by them. We hypothesized that deschampado causes a minimal disturbance, thus maintaining shrub layer characteristics and a light environment similar to unmanaged forests.

养牛场的可持续干旱森林管理：与滚筒砍伐相比，deschampado 做法对灌木层和光环境的影响

由于农业和畜牧业集约化，查科地区面临着土地覆盖变化。林牧实践采用滚筒砍伐，其中灌木层被完全去除。干扰会引发植被演替过程并促进灌木重新定植。滚筒砍伐只会去除空中器官，因此一些物种会重新发芽，这可以改变它们的结构。为了寻找可持续的替代方案，参与性方法引入了“deschampado”，其中涉及低强度干预，并播种耐荫饲料草。该研究旨在比较滚筒砍伐和德斯坎帕多，关于灌木层的覆盖、组成和结构的变化，以及它们产生的光环境的变化。我们假设 deschampado 造成的干扰最小，从而保持灌木层特征和类似于未管理森林的光照环境。
