Biodiversity loss and conservation in fragmented forest landscapes: the forests of montane Mexico and temperate South America.

Book cover for Biodiversity loss and conservation in fragmented forest landscapes: the forests of montane Mexico and temperate South America.

Description

This book is the result of an international collaborative research effort focusing on the tropical montane forests of Mexico and the temperate rain forests of southern South America. The over-all aim of the research was to investigate the impact of human activity on the key processes influencing biodiversity in fragmented forest landscapes, and to use the research results to develop practical tool...

Identification of priority areas for conservation in south-central Chile.

There is an increasing awareness in Chile of the need to improve the representation of the country's forest types in the national network of protected areas, and to reduce the impacts of the native forest conversion to other land uses. One promising strategy is to use the principles of systematic conservation planning to identify important areas for the conservation of biodiversity. In this chapter we use information on the vulnerability of native forest to threatening processes and information on the distribution of forest types to systematically determine priorities for biodiversity conservation in the temperate forest region of south-central Chile. We find that the existing reserve network covers approximately 12% of the study region, and that only 53% of the area of native forest estimated to be present before European settlement remained in 1997. Temperate forest is now largely restricted to the upper elevations of the Andean and coastal ranges, within a matrix of pasture, agriculture and plantations. We develop a model of the conversion of native forest to plantations and predict conversion to be more likely in warm and low rainfall areas that are close to towns and roads and on red clay and mixed alluvial soils. We argue that the priority areas for conservation should be currently unprotected areas that are vulnerable to plantation conversion and that, if lost or degraded, will result in conservation targets being compromised. We find the Evergreen forest type to be a priority for conservation owing to its lack of representation in the existing reserve network and the degree to which it has been cleared. By focusing our conservation efforts on areas with the greatest conservation value and the highest likelihood of losing significant portions of this value, we will be able to achieve maximum impact for conservation investments in south-central Chile.
