Serotinous Survival Strategies

Over the millennia, plants and trees native to fire-prone regions have evolved a number of adaptations that allow them to persist in these challenging habitats. Some plants have subterranean rhizomes that rapidly regenerate the aboveground portion of the plant after it burns in a fire. Others produce seeds that lie dormant until exposed to fire,…
