and plant species have adapted to regenerate after or to survive a
fire. Some plants that live in fire-prone areas have adaptations that
help to ensure the survival of the species in that area. Certain pines,
for instance, have what are called serotinous cones, which are held
tightly closed by a sticky resin. When the cones are exposed to the
heat of a fire, the resin melts and large numbers of stored seeds
are released. When fires occur, large stands of Lodgepole Pines may
burn, but the seeds produce a massive regeneration or seedling trees
after the fire. An individual tree will not survive a fire, but the
species will reproduce and thrive because of the fire. These fire-adapted
trees are quick to reseed an area that has been burned.
trees, such as the Ponderosa pine trees, are adapted to survive fire.
With their thick bark, relatively sparse foliage and few lower branches,
Ponderosa Pine trees can survive many fires throughout their long
life. Fire benefits Ponderosa Pine communities by removing other plants
and trees that compete for water and nutrients in the soil. Many shrubs
and plants have roots or bulbs that are able to produce new growth
even if the above-ground parts of the plants are burned.
