Ignition Component fuel moisture (FFM) which expresses the effective moisture content of the fine fuels. The closer the initial temperature of the fuel is to the ignition temperature, the more likely a fire will result when a firebrand in introduced into the fine fuel complex, since not a much energy is required to raise the fuel particle to its ignition temperature. Ignition Component The Ignition Component is a number which relates the probability that a fire will result if a firebrand is introduced into a fine fuel complex. The ignition component can range from 0 when conditions are cool and damp, to
Henderson archaic pigeon extension, the dodo. The pigeon became extinct following human colonisation of Henderson, an event that had occurred by 1050 CE. Two of the other three species of pigeon on the island also disappeared, as did other birds. Henderson archaic pigeon The Henderson archaic pigeon ("Bountyphaps obsoleta"), or Henderson Island archaic pigeon, is an extinct bird in the Columbidae, or pigeon family. It was described in 2008 as a new genus and species from subfossil remains found on Henderson Island in the Pitcairn Group of south-eastern Polynesia. The genus was named for both the ship HMS "Bounty" with which, following the
