Key to bridging knowing–doing gaps is analysis of the constraints binding interactions between decision-makers and conservation biologists to clarify the problems they address. We apply this analysis to decision situations in the Northern Vosges (France), which illustrate three kinds of constraints: governance, framework and initiative. We explore how conservation biologists can mitigate constraints so as to foster more ambitious conservation actions in each case. The first case explores attempts at reintroducing the lynx (Lynx lynx). In this case, we show that governance plays a key role, in the sense that conservation actions should focus on improving the acceptability of reintroductions to key stakeholders. The second case refers to water monitoring schemes. Here we show that framing is the dominant constraint. This means that conservation actions are tightly limited by the use of a restrictive scientific apparatus. The last case study, fish stock protection, is constrained by initiative. Here, decision-makers have too much leverage to implement solutions they favour, even if they are not the best options in conservation terms. Exploring how our framework relates to the existing literature allows us to highlight its usefulness for rationalizing conservation problem framing and for strengthening the ambitions of conservation actions.
