Abstract Protected areas represent the main tool for halting the continuing loss of biological diversity. The number and extent of protected areas is gradually increasing, but this expansion does not always ensure the efficient protection of key species, habitats, and ecosystem functioning. Today, the Natura 2000 network encompasses more than 27 000 sites, representing the cornerstone of conservation strategies throughout Europe. About one‐fifth of the terrestrial surface of the European Union (EU) is now covered by the Natura 2000 network; yet, knowledge remains limited about its efficiency to encompass inland water ecosystems sufficiently. This study aimed to determine the extent to which the Natura 2000 network covers 5132 European lakes that host fish species and freshwater lake habitat types of conservation interest. A key question investigated was whether the protection coverage of the water bodies reflects the coverage of the terrestrial areas surrounding the lakes. Geographical, socio‐economic, and political parameters were considered as potential descriptors of the observed patterns. The results demonstrated that although most of these sensitive ecosystems have high protection coverage at water body level, Natura 2000 largely ignores their surroundings. At the catchment level, lower conservation coverage was detected, raising concerns about whether the network offers sufficient protection to wetland species, habitats, and ecosystem functioning against numerous threats operating in the terrestrial areas surrounding water bodies. The results also identified different patterns of coverage in different EU Member States, which might reflect a lack of common practices regarding the implementation of key EU directives. This study highlighted the necessity of redefining conservation planning towards a systematic, integrated approach. The spatial properties of the landscape and the distribution of potential pressures should be considered at the catchment level of water bodies, as these pressures alter the functionality and services of inland water ecosystems.
