 Fire in the "campo rupestre" symbolizes both a threat as well a natural phenomenon; readily available fuel combined with environmental conditions facilitates the occurrence of natural and anthropic-related fires.While fire boosts the reproductive system of some species by positively impacting the number of seeds or seedling recruitment it can also negatively affect the sparse and relictual forests intermingled with the more common rocky outcrops and grasslands.Even lineages that rely on fire can be negatively influenced depending on its frequency.
