In the event of a wildfire, plants can’t run. Pyrophytic plants are simply plants that can tolerate fire. The term pyrophyte comes from “pyros” (fire) and “phytos” (plant). There are three types of pyrophytic plants: passive pyrophyte, active pyrophyte, & pyrophile. Passive pyrophytes can tolerate fire. An active pyrophyte encourage the creation of a wildfire. A pyrophile requires a wildfire to prompt reproduction. Passive pyrophytes tend to have distinctive traits that allow them to tolerate fire. For instance, they have thermal insulation. They achieve thermal insulation with either bark, dead leaves, or moist tissues. With thick bark, plants such as giant sequoias can withstand wildfires to a certain extent. This allows them to protect their tissues. However, these passive pyrophytes can perish to extraordinarily intense fires. Plants, like the Australian grass tree, have dense, dead leaves circling their stems can withstand the heat of a wildfire. In addition, some plants like the Protea species, have moist tissues. These tissues double as a way to insulate against the heat and protect against dehydration. Trees found in species like the pines species has a tall crown and minimal amount of lower branches. This can help defend against wildfires, thus allowing for reduced damage. Active pyrophytes contain volatile oils that can cultivate wildfires. In addition to these unique trees and shrubs, they also possess qualities commonly found in passive pyrophytes. For example, the Eucalytptus of Australia rely on starting wildfires in order to prevent other tree species from invading their habitat. Of course, the Eucalyptus of Australia depend on their fire-resistant qualities, so they can survive their own fires. Pyrophiles typically require wildfires to start or complete their cycle of reproduction. Plants like the Banksia contain serotinous cones or fruits. These cones/fruits are covered in resin, which can only be melted by the fire. Once the resin is melted, the seeds can be released.  For instance, the increasing temperature and smoke break seed dormancy, thus making seed germination more favorable. Many plants begin to abundantly flower once they experience damage from a wildfire. This is due to the ash – fertilized soil. For example, several members of the fire lily genus Cyrtanthus only flower after witnessing a wildfire. Plenty of plants have adapted to resprout if they’re damaged from a wildfire. Some Eucalyptus species have buds protected beneath the bark of the trunks. When the trees burn, these buds emerge to produce new leaves.
