这篇文章提出了第一个明确的准则，再生橡树在阿巴拉契亚山脉中部。本文的目的是（1）描述指南所依据的研究基础，（2）为用户提供在该领域应用指南所需的说明、数据收集表格、补充表格和决策图。该指南的主要研究基础是一套定量模型，该模型在收获前估计林分从提前再生和树桩萌芽中再生橡树放养的潜力。更新潜力是通过预测的橡树种的蓄积量来衡量的，表示为在新林分中，在其第三个十年（21 - 30年）的完全（100%）蓄积量的百分比。林下分类系统与模型结合使用，以帮助确定潜在的障碍，再生发展。模型的结果和其他数据，目前的立场条件的决策图中使用，以确定处方，实现强大的组成部分，橡树再生后，立场收获。当林分的橡树再生潜力足以满足管理目标时，建议清除上层林。否则，建议采用旨在提高实生苗橡树再生潜力的处方。
This article presents the first explicit guidelines for regenerating oaks in the central Appalachians. The objectives of this paper are (1) to describe the research foundation on which the guidelines are based and (2) to provide users with the instructions, data collection forms, supplementary tables, and decision charts needed to apply the guidelines in the field. The principal research foundation for the guidelines is a set of quantitative models that estimate, in advance of harvest, a stand’s potential to regenerate oak stocking from advance regeneration and stump sprouts. Regeneration potential is measured by the predicted stocking by oak species, expressed as a percentage of full (100%) stocking, in the new stand in its third decade (21‐30 years) after overstory removal. An understory classification system is used in conjunction with the models to help identify potential barriers to regeneration development. Model results and other data on current stand conditions are used in the decision charts to identify prescriptions for achieving a strong component of oak regeneration after stand harvest. Overstory removals are recommended when the stand’s oak regeneration potential is adequate to meet management goals. Otherwise, prescriptions designed to enhance seedling-origin oak regeneration potential are recommended.
