>Perhaps the most amazing fire adaptation is that some species actually require fire for their seeds to sprout. Some plants, such as the lodgepole pine, Eucalyptus, and Banksia, have serotinous cones or fruits that are completely sealed with resin. These cones/fruits can only open to release their seeds after the heat of a fire has physically melted the resin. Other species, including a number of shrubs and annual plants, require the chemical signals from smoke and charred plant matter to break seed dormancy. Some of these plants will only sprout in the presence of such chemicals and can remain buried in the soil seed bank for decades until a wildfire awakens them. The image shows lodgepole pine seedlings growing next to the charred remains of their parent plants following the 1988 Yellowstone National Park fires.
