Yellow-Poplar: A Component of Climax Forests?
Although classed as intolerant and requiring exposed mineral soil for vigorous regeneration, yellow-poplar (Liriodendron tulipifera L.) has long been considered a dominant in climax stands on good sites in the southern Appalachians. More in keeping with its silvical traits is its role as an aggressive pioneer on disturbed sites. The disturbances necessary to perpetuate this light-demanding tree in otherwise stable climax communities are explained by the species' growth habit. The trees reach great size and age at maturity, and their dominant crown position makes them highly susceptible to windthrow. Their falling thus creates openings and exposes mineral soil sufficient for regeneration.
