Te bark 's low thermal conductivity and high shavelure content allow to t with stand brief, intense ground fires. Additionally, the bark is often deeply furrowed and d compose of long, fibrous strand thathelp shed flames andd prevent heat from intrarating deeply. Thies coxn reduces the risk of letal damage te to essential vascular tissues and growing points.

For example, thee giant secoia 's thick bark cak can be up to 60 centotimeters (2 feet) thick, which insulates the tree frem heat that can reach over 1,000 ° C (1,832 ° F) in wildfires. This adaptation allows mature sequoias to docue fire that would cost tear species.

By limiting these ladder fuels, surface fires are less less likely to escate into devastating crown fires, which are far more destructiva and letal to mature trees. Furthermore, tree with high, open crown structures allow wings tos pass thriph, reducing heat acculation around the trunk and canopy.

In addition, some species, like the ides 1; Xi1; FLT: 0 XI3; XI3; Eucalyptus precidi1; XI1; FLT: 1 XI3; XI3;, have tall, smooth trunks that shed bark in long strips, preventing bark acculation that could otherwise fuel fires climbing the trunk.

Ewolucjonizary Tradeoffs

There is a well-documented trade-off between resproting ability and seedling recruitment. Species that ar e strong resprouters tend to produce fewer but larger, more energy-coursive seeds, investing resources into bud reserves. Conversele, obligate seeders - plants that rely entirely on seed germination after fire - produce vast numbers of small, esily dispenseed seeds.
