Modification of the flora composition in edges of fragmented Austrocedrus chilensis forests in Patagonia

Abstract: In the Patagonian Andes of Argentina, Austrocedrus chilensis is one of the native tree species most affected by forest fragmentation, resulting in remnants stands surrounded by grasslands. We studied vegetation in the edges of stands of dense A. chilensis adjoining areas that were cut 10 years earlier, with special reference to A. chilensis regeneration, diversity, abundance and specific species distribution. We found that the original composition of the vegetation had been strongly modified, there was a high … Show more

“…Land use change and carbon content in Abies religiosa forest 89 (Matti et al, 2010), Picea asperata in China (Zhong-Sheng et al, 2010), and Astrocedrus chilensis in Patagonia (Carabelli et al, 2006). On the other hand, considering the probabilities of landscape change in the El Conejo ejido, assuming that the present conditions are maintained, the most likely scenario is that the forest area will be maintained or that there will be a change from shrubland + pasture to shrubland, both with a probability of 92% of occurring.…”

“…El estudio integrado de las dos formaciones vegetales en contacto permite comprobar esta circunstancia, cuantificando la respuesta más o menos interdependiente de las propiedades de cada una. En caso de interacción entre ellas, cabe esperar una cierta autocorrelación espacial en la respuesta de parámetros ecológicos de las comunidades herbáceas (Naveh y Whittaker 1979, Chen et al 1992, Murcia 1995, Meiners y Pickett 1999, Ramírez-Sanz et al 2000, Carabelli et al 2006, de Miguel et al 2005. A menudo, su existencia suele expresarse mediante una respuesta gradual de esos parámetros a lo largo de transectos que recorren perpendicularmente la línea de contacto entre las formaciones.…”

“…En estos valles son frecuentes los fragmentos de bosque nativo de lenga en una matriz general de pastizales abiertos (praderas) cuya presencia se ha visto favorecida por una intensa actividad ganadera. En las primeras décadas del siglo XX se introdujeron varias especies herbáceas no nativas (Silva et al 1999), que han coexistido con las nativas con diferente éxito en función del tipo de la formación vegetal considerada -bosque o pradera-(Damascos y Rapoport 2002 Carabelli et al 2006). …”
