Fire ecosystems have vegetation that has adapted to the frequent fires in arid regions. The fires, which usually only flare up briefly, rejuvenate the stands and the resulting ash fertilizes the soil. The seeds of some types of plants are found in fruits or cones that only open when exposed to the heat of a fire. In this way, they find optimal growth conditions after the fire. Such plant species, like all plant species in general, which are adapted to frequent fires are called pyrophytes .

Regular fires are an essential part of nature in fire ecosystems . If fires are prevented because they are e.g. B. are seen as a threat to human settlement or economic use, combustible material accumulates in large quantities. The energy released in the event of a fire also destroys plants adapted to bush fires .

Such ecosystems are mainly found in semi-arid areas, e.g. B. in Australia , California , the Cape flora of South Africa and in the Mediterranean area .
