Our Eucalyptus trees similarly need fire to reproduce, but rely on smaller grass and shrub based fires to produce the heat necessary to activate their seeds. The heat opens their seed cones, their seeds are released, the flames clear the earth for their germination. While lesser trees blaze around them, the giant sequoias stand virtually unscathed by the flames. The dominant trees in coastal redwood forests range from several hundred years to over two thousand years. This way of reproduction results in trees that are genetically identical to the previous tree. Trees that originate from seeds do not experience rapid height growth until they are over 10 years of age. This helps prevent fire from getting to the more easily burned sapwood behind the bark. https://www.nps.gov/parkhistory/online_books/shirley/sec7.htm They're remarkably fire resistant. As opposed to serotinous cones, which protect enclosed seeds during a fire, the actual seeds of many plants in fire-prone environments need fire, directly or indirectly, to germinate. To understand how this is even possible, you need to know about the numerous ways that redwoods can reproduce—some of which involve cloning themselves. Bark – The bark of mature redwood trees can grow at least a foot thick, creating a great protective shield from fires. Giant sequoias depend on fire to reproduce. 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. Perhaps the most amazing fire adaptation is that some species actually require fire for their seeds to sprout. Large, down trees may lie on the forest floor, gradually decaying, for many hundreds of years. During a recent hike in the Berkeley hills with a friend, the topic of cones came up. This bark has high water content, which also helps prevent it from burning easily. Fire-activated seeds. Lodgepole pines, ubiquitous across much of the West, are one of the first species to grow after a fire because of their serotinous cones. “Fire is a natural part of the redwood ecosystem,” says Anthony Ambrose, a forest ecologist and redwood expert. Two decades later, when the Pierce Fire moved through Sequoia National Forest, it burned old-growth trees. These large, erect, dead trees may remain standing for decades, or even centuries. There is an activity I like to do with students to teach them about cones: I bring in a small redwood cone and a large sugar pine cone and ask the students which … Snags are another characteristic feature of an old-growth forest.
