Evaluación biogeográfica a partir del método lanbioeva de cinco poblaciones del bosque mediterráneo con palmas (Jubaea chilensis) de Chile.

Abstract

This paper is based on a research work developed over 25 years that aims to consolidate a method for making biogeographical inventories and evaluations of vegetal landscapes in mid and high latitudes. To date, the method has been applied to different ecosystems within the Iberian Peninsula, Scandinavia, Balkans, Chile, Nicaragua, and Brazil. As consequence of a research stay in 2008, the highest score by applying the method to a specific formation, the Mediterranean forest with Chilean Palm, was recorded. This article focuses, exposes and analyzes the overall results obtained in the area of five populations located among their northernmost and southernmost area of distribution limit. Moreover, this paper expects to make a diagnosis about these formations in a global sense and it also provides a guideline in order to ensure its management and planning in a correct way. The methodology is based on a systematic inventory of different units along with an assessment based on natural, territorial, cultural, management and risks criteria. The results again confirm general values which, however, in this case do not reach the registered in the area of Valparaiso and Viña del Mar. However, criteria such as the territorial or mesological are still counting on big scores.
