Abstract

In several separate experiments, it was found that survival of advance seedlings after clearcutting in Allegheny hardwood stands is a function of initial seedling size-larger seedlings survive best. Age, number of leaves, and leaf size also were important determinants of survival. In Allegheny hardwood stands, where advance regeneration is typically less than 1 foot in height, seedlings that are less than 1 or 2 inches tall, or that have fewer than two normal-size leaves, or that are 1 year old should not be considered as established in advance regeneration assessments. Advance seedlings that originated under a shelterwood canopy survived overstory removal much better than seedlings from an uncut stand. Therefore, the final removal cut of a shelterwood sequence can be made as soon as there are an adequate number of seedlings.
