These fires allow a new generation to emerge by exposing mineral soil, increasing sunlight proliferation, and melting the resin of the tree's serotinous cones (Tackle 1961).
It is usually painful and covers all the body while the serotinous type is accessed at adulthood and mostly covers head and neck.
Populations can quickly reestablish in the wake of a forest fire due to the species' serotinous cones, or cones coated with a resin that must be melted by fire before opening and releasing the seeds within.
The ecosystem has species adapted to >0% disturbance, such as lodgepole pine (Pinus contorta) serotinous cones that release seeds after fire, and thus complete fire suppression to 0% area burned does not produce a sustainable ecosystem.
pungens are serotinous and stand regeneration requires medium to high-intensity fires that release seed, expose mineral soil, and open the forest canopy.
The fire-insured serotinous form is coated with a strong resin that seals the cone shut.
In this experiment SC704 was used which is a serotinous cultivar with 140-150-day growing season.
Serotinous (late-to-open) cones have been reported in Pinus contorta (Lotan, 1967, 1976; Perry & Lotan, 1979; Muir & Lotan, 1985a, 1985b; Despain et al.
But that's good news for the tree, since fire opens its serotinous cones to release the seeds, starting the process over again.
GDD in serotinous varieties (80-12-1) is more than the early varieties (80-17), consequently late varieties in during the growing season, need to more GDD to complete their growing.
The cones of Table Mountain pine, like those of many fire-dependent pines, are serotinous, meaning they remain closed for some time after maturity and open only after exposure to high temperatures, like those associated with forest fires.
