WiSE is a tool designed to provide safe separation distance calculations to wildland firefighters, developed to support the model created at the USFS Fire Lab in Missoula by Dr Bret Butler.

This new tool gives firefighters the crucial ability to identify suitable safety zones while in the field. With inputs based on direct observations in the field, wildland firefighters now have the ability to quickly calculate the distance needed to provide themselves and others, safety from burn injury. wildland firefighters can enter on-scene observed data via parameters such as: Wind, Slope, Fuel Height and Resource Information.
