Spontaneous and piloted ignition of ponderosa pine (Pinus ponderosa Laws.) needles were investigated in an isothermal atmosphere. Four levels of sample moisture content were tested and minimum heat flux intensities required to produce ignition, times to ignition, and surface temperatures at time of ignition were recorded. Piloted ignition occurred at lower flux intensities and in less time than did spontaneous ignition. A significant difference in delay time to ignition was found to exist for sample moisture contents above 7.7 percent.
