A systematic conservation planning approach to fire risk management in Natura 2000 sites.

摘要: A primary challenge in conservation biology is to preserve the most representative biodiversity while simultaneously optimizing efforts associated with conservation. In Europe, implementation of Natura 2000 network requires protocols recognize and map threats identify specific mitigation actions. We propose a systematic planning approach optimize management actions against based on two fundamental parameters: values threat pressure. used software Marxan fire plan coastal southern Italy. address three questions: i) Which areas are at high risk? ii) valuable for threatened biodiversity? iii) should receive priority risk-mitigation optimal effect?, iv) which fire-prevention feasible areas?. The spatial units were derived from distribution maps 18 habitats 89 vertebrate species concern Europe (Habitat Directive 92/43/EEC). pressure map, defined as probability, was obtained digital layers risk frequency. settings follows: a) 40 × 40 m, b) features all European occurring study area, c) targets according sensitivity extinction features, d) costs determined complement probabilities. identified 23 concentrate reduction fire-induced effects. Because traditional prevention not policy included areas, alternative practices that allows vegetation structure. proposed has potential applications multiple landscapes, scales could be extended other natural including protected areas.
