El paisaje rural antropogénico de Aisén, Chile: Estructura y dinámica de la vegetación [The anthropogenic rural landscape of Aisen, Chile: Structure and vegetation dynamic]
We studied the dynamic of the vegetation degradation in a rural anthropogenic mosaic vegetal landscape of the Aisen Region, Chile to establish relations of origin in space and time between communities and propose series of degradation. With plant sociological methodology we make up 50 vegetation sam...
