The management of wildfire is a dynamic, complex, and fundamentally uncertain enterprise. Fire managers face uncertainties regarding fire weather and subsequent influence on fire behavior, the effects of fire on socioeconomic and ecological resources, and the efficacy of alternative suppression actions on fire outcomes. In these types of difficult decision environments, even well-trained and experienced individuals can become susceptible to cognitive limitations and decision biases, as indicated by several recent analyses of fire manager decision making. This extended abstract focuses on fire management decision making under uncertainty, in relation to current decision support provided by the Wildland Fire Decision Support System (WFDSS), offering several recommendations to improve decision content and process.
