Calocedrus decurrens
One tree species in direct competition with bigcone is "Calocedrus decurrens", with preliminary post-fire regeneration of this species exponentially greater than bigcone. After 1 or 2 years after the Station fire in 2009 on the Angeles National Forest, there was an estimated 20:1 cedar:bigcone seedling density in fixed radius plots on Mount Wilson. It may be more appropriate to perform population stability estimates up to 5 yrs or much later (i.e. 20 yrs) after a large conflagration due to the potential for immediate and delayed post-fire sprouting and regeneration and interplant competition, as well as the well-noted strategy of seed germination in shrub understories, which is likely to escape detection by surveyors until much later in its life.
