ABSTRACT

The Natura 2000 protected area network is the cornerstone of European Union's biodiversity conservation strategy. These protected areas range across multiple biogeographic regions, and they include a diversity of species assemblages along with a diversity of managing organizations, altogether making difficult to pool relevant sites to facilitate the flow of knowledge significant to their management. Here we introduce an approach to navigating protected area networks that has the potential to foster systematic identification of key sites for facilitating the exchange of knowledge and diffusion of information within the network. To demonstrate our approach, we abstractly represented Romanian Natura 2000 network as a co-occurrence network, with individual sites as nodes and shared species as edges, further combining into our analysis network topology, community detection, and network reduction methods. We identified most representative Natura 2000 sites that may increase the transfer of information within the national network of protected areas, detected clusters of sites and key sites for maintaining network cohesiveness, and highlighted the subsample of sites that retain the characteristics of the entire network. Our analysis provides implications for protected area prioritization by proposing a network perspective approach to collaboration rooted in ecological principles.

 Conclusions

Our network approach provides a tool for building collaborative partnerships for managing Natura 2000 sites at the national level. Effective collaboration between site managers relies on improved communication, and protecting the same species might be a good opportunity to share conservation strategies and cooperation. Additionally, our analysis highlights implications for protected area prioritization by taking a network assessment approach to collaboration, while being rooted in ecological principles. The network theory approach could be also used in addressing management and representation gaps in the protected areas (Hoffmann et al., 2018) by highlighting isolated Natura 2000 sites from a knowledge transfer perspective. The establishment of Natura 2000 network along with the advances in designating the sites, was the initial step in ensuring the protection of habitats and species for long-term (Evans, 2012). Strengthening the implementation of conservation policies and adopting best management strategies should provide new knowledge transfer opportunities to support effective Natura 2000 network management (Hochkirch et al., 2013; Pellegrino et al., 2017).
