Language barriers in conservation: consequences and solutions

Language barriers can severely hinder the advance of conservation science and its contribution to addressing the biodiversity crisis. We build a framework for understanding how language barriers can impede the evidence-based conservation of biodiversity in three ways: barriers to (i) the generation of evidence by non-native English speakers; (ii) the global synthesis of evidence scattered across different languages; and (iii) the application of English-language evidence to local decision making. We provide evidence, building on a growing body of literature, that quantifies the three consequences of language barriers in conservation. We also propose a checklist of solutions for reducing language barriers in conservation by addressing language disparities among scientists, promoting linguistic diversity in conservation, and making conservation science and its communication multilingual.
