Based on various USFS docs, for roads in the USFS system I'm using:

For Forest Highways (generally major paved roads): ref=FH nn (e.g. 
name=Angeles Crest Highway + ref=FH 61).
For Forest Roads/Routes/Truck Trails: ref=FR yDxx (e.g. name=Upper Monroe 
Road + ref=FR 2N16)
For Forest Trails: ref=FT yDxx (e.g. name=Heaton Flat Trail + ref=FT 8W16)
