造林的应用对森林健康、蓄积水平和土地所有者的长期经济利益有重大影响，但关于在整个景观中应用什么样的处理方法的信息却很少。我们开发了一种分类树，使用客观的库存数据将收获分为12种收获类型之一，基于收获前和收获后的库存水平，大小分布和树木质量。结果表明，商业皆伐和高等级的开发性处理可能比理想的更常见，而一些“经典”的造林技术，如造林皆伐和种子树收获，是比较罕见的。处理的分布在纽约和新英格兰各地各不相同，与自然干扰的历史分布几乎没有相似之处。此外，收获前和收获后的物种组成显示出在某些处理中优先去除有价值物种的趋势。结果表明，需要进一步努力，使收获的做法符合最新的造林和生态研究。
The application of silviculture has major implications for forest health, stocking levels, and landowners' long-term economic interests, yet little information exists about what treatments are applied across the landscape. We developed a classification tree that uses objective inventory data to classify harvests into one of twelve harvest types, based on pre- and post-harvest stocking levels, size distribution, and tree quality. Results indicate that exploitative treatments like commercial clearcutting and high-grading may be more common than is desirable, while some "classic" silvicultural techniques, like silvicultural clearcuts and seed tree harvesting, are comparatively rare. The distribution of treatments varies across New York and New England, and bears little resemblance to the historical distribution of natural disturbances. Furthermore, pre- and post-harvest species compositions show a tendency in some treatments to preferentially remove valuable species. Results suggest further efforts are needed to bring harvesting practice in line with the latest silvicultural and ecological research.
