The Defects and Some Other Characteristics of Virgin-Growth and of Second-Growth Commercial Shortleaf Pine Lumber1

Key Points

Second-growth lumber shows significant differences in quality compared to virgin growth, affecting its utility.
Foresters may misdirect their efforts towards volume production without considering lumber grade, impacting outcomes.
The study focuses on one species but emphasizes the broader implications for lumber quality in forestry management.
Understanding these differences is crucial for making informed decisions about lumber resources and production.

Abstract

Abstract The forester who strives for volume production and neglects a consideration of the probable grade and quality of the second-growth lumber product may find his efforts misdirected. Second-growth lumber from most species differs markedly from that of virgin growth and its utility varies as a consequence. The study reported in this article, although limited to one species, is timely and important in that it directs attention to the differences between the two classes of lumber. 2
