FCCS adopted the Integrated Taxonomic Information System (ITIS) database as its standard for its species list (including its ruling re species scientific name acceptance). The ITIS Taxonomic Serial Number (TSN) is used as the species ID in FCCS fuelbed XML files. The following are the species currently supported by FCCS, as each species is assigned a suite of fire-relevant intrinsic qualities (e.g., particle density, accelerant status) needed in calculations. Contact our team if you need species added to our master list.
