Biodiversity has gained huge importance as a fundamental concept for environmental conservation, yet the physical support of biodiversity (e. g., soils, landforms and geological units, recognized as geodiversity) remains little observed within the scientific community. At the same time, advances in effective biodiversity conservation in critical hotspots, as in Central Chile, are limited due to the lack of public lands, direct impacts on biodiversity like urban sprawl and wildfires, and the weakness of governance approaches for effective conservation planning. Here we discuss possibilities for improving bio(geo)cultural conservation in Mediterranean Central Chile through a landscape approach.
The conservation of biodiversity in Mediterranean Chile requires a greater coverage than that represented in the Protected Wild Areas of the State (SNASPE) and Private Protected Areas (APP) are complementary alternative for conservation. The study of biodiversity in APP is scarce, ignoring its contribution to the conservation. The small mammals assemblage of the APP Bioparque Puquén and surroundings was described comparing the species richness, relative abundance and diversity index of Margalef inside and outside the park. Using the Morisita-Horn similarity index and a cluster analysis, the small mammals assemblage was compared between sampling points categorized in different biotopes. Endemic and native species were more abundant outside the APP. There were no significant differences in specific richness or diversity inside and outside the APP. The small mammals assemblage was grouped into biotopes of dense native vegetation and prairies, ravines and seasonal waters. The park would act as buffer area, protecting the nearby areas of the Los Molles-Pichidangui Priority Site. The importance of rocky outcrops as a habitat for endemic species of small mammals and protecting the areas adjacent to the BioParque is discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
