Accounting for the 'network' in the Natura 2000 network...

Worldwide, we are experiencing an unprecedented, accelerated loss of biodiversity triggered by a bundle of anthropogenic threats such as habitat destruction, environmental pollution and climate change. Despite all efforts of the European biodiversity conservation policy, initiated 20 years ago by the Habitats Directive that provided the legal basis for establishing the Natura 2000 network, the goal to halt the decline of biodiversity in Europe by 2010 has been missed. Hochkirch et al. (2013, Conserv. Lett. 6: 462-467) identified four major shortcomings of the current implementation of the directive concerning prioritization of the annexes, conservation plans, survey systems and financial resources. However they did not account for the intended network character of the Natura 2000 sites, an aspect of highest relevance. This response letter deals with this shortcoming as it is the prerequisite, over any other strategies, ensuring a Natura 2020 network being worth its name.
