Abstract

Annex I habitat types are a key factor for biodiversity conservation in Europe and distribution maps are essential for assessing their conservation status.We aim to increase the responsiveness to habitat knowledge needs and to propose the use of data collected at local scale for assessing a key indicator such as the Area of Occupancy (AOO) of habitats. In this paper, starting from the 4th Report of Habitats Directive data, we present a multi-source approach that allows national habitat distribution maps to be refined and their AOO estimated, by combining certified available information on habitat maps and vegetation databases.For the first time a comprehensive up-to-date knowledge on habitat distribution at national scale is now available; our approach will be an essential tool for the implementation of the Habitats Directive and to achieve the goals of EU biodiversity strategy in Italy.

如何在国家范围内改善栖息地类型的分布图

摘要

附件一的栖息地类型是欧洲生物多样性保护的关键因素，分布图对于评估其保护状况至关重要。我们旨在提高对栖息地知识需求的响应速度，并建议使用当地规模的数据评估关键指标例如栖息地的占用面积（AOO）。在本文中，我们从《人居指令第四次报告》数据开始，提出了一种多源方法，该方法可以通过结合栖息地图和植被数据库上已认证的可用信息来完善国家栖息地分布图并估算其AOO。现在可以获得关于国家规模的栖息地分布的最新综合知识；
