Despite the increasing challenges wildfires are posing around the globe, and the flourishing production of high-quality wildfire scientific knowledge, the ability of fire science to impact knowledge on the ground, for people, society, economy, and the environment, in a way that facilitates change in the current wildfire management system has been limited. We believe that one reason for this limited impact is due to the fragmentation of this scientific knowledge. Therefore, we propose a Translational Wildfire Science (TWFS) as a new field of knowledge that captures the comprehensive dynamics of wildfire events, that provides information relevant, useful, and accessible to practitioners and citizens, and that facilitates the transfer of scientific knowledge into practice. The foundations of TWFS, including the main principles, the overarching characteristics, and the approach of a TWFS scientist, are presented. Finally, the next steps to be undertaken to consolidate TWFS as a new scientific field are identified.
