Biodiversity Conservation in Human-Dominated Landscapes: Toward Collaborative Management of Blue–Green Systems

Maintaining ecological connectivity is crucial for biodiversity, yet effectively managing interconnected areas through actor collaboration is challenging. This study examines collaboration through social–ecological fit in interconnected aquatic “blue” and terrestrial “green” areas, encompassing natural and semi‐natural elements, in human‐dominated landscapes. Combining species distribution models and connectivity analyses focused on declining amphibians and survey data on actors’ area management and collaboration within interconnected areas, we create a spatially explicit social–ecological network that we analyze using network models. Results highlight diverse ecological dependencies shaping actor interactions. Strong collaboration is observed in interconnected blue‐rural‐green areas, whereas blue‐urban‐green areas lack collaboration, with minor rivers and urban‐green spaces at the network's core plagued by social–ecological misfit. Strengthening collaboration in these areas is essential to prevent further ecological network degradation. Incorporating a spatially explicit social–ecological perspective covering diverse blue and green areas guides targeted interventions and fosters effective conservation policy and practice.
