摘要：The objective of this paper is to analyse the impacts caused by the concentration of land holdings on the landscape of Escurial de la Sierra, a village located in the south of the province of Salamanca (Spain). This village is part of the Biosphere Reserve of the Francia and Bejar mountain ranges (UNESCO 2006) due to the importance of its vegetation/flora, fauna and landscape. In order to observe the effect of the concentrations, several satellite images taken before and after the concentration process have been compared. The creation of 8 metre wide tracks by cutting trees and flattening the land has caused the disappearance of many hectares of forests which were either mature or in a process of regeneration. The fencing of the new parcels of land is causing the fragmentation and insularity of the land, resulting in a major impact on the metapoblational dynamics of the rich invertebrate land fauna.
