The web-based Interagency Fuels Treatment Decision Support System (IFTDSS) was designed to provide fire and fuels managers with a single software solution to manage the many data types, software applications, and tools available for fuels treatment planning. The IFTDSS project was initiated in 2007 by the Joint Fire Science Program (JFSP) and the NWCG Fuels Management Committee who saw a need for a user-friendly, web-based decision support system to address the proliferation of software tools and systems in the fire and fuels treatment domain.
