Modeling fuels and treatment effects in 3D with STANDFIRE

Fuel treatments offer a means of proactively mitigating risks to firefighters and communities, and to restore altered ecosystems. The cost and potential impacts associated with implementing such treatments, however, suggest a need for thorough understanding of their effectiveness before they are carried out on the ground, particularly at landscape scales. At present, modelling tools used to evaluate fuel treatments are often limited in their ability to represent fuels or fuel/fire interactions. This is particularly true for treatments that seek to modify forest spatial patterns; most modelling frameworks are not spatially explicit and thus can only describe forests in terms of overall average characteristics. Here, we describe STANDFIRE, a prototype 3D platform for modeling wildland fuels and fire behavior at stand scales. Leveraging a powerful core modeling architecture, STANDFIRE links a forest growth model to physics-based fire behavior models, providing a means by which detailed fuels data can be used as input in physics-based fire behavior simulations which can explore fuel treatment effectiveness or sensitivity to environmental conditions. We describe the model, some applications, and plans for continuing development.
