Bird and forest communities in a northern Michigan jack pine stand before and after logging, 2013-2018

This package contains data associated with documentation of breeding-season bird communities in a dry, jack pine and mixed red pine-jack pine forest in Marquette Co., MI. In addition to repeated surveys, 2014-2018, of bird presence in a network of 45 study plots, the package includes vegetation data collected on the same plots 2013-2017. At initiation of the study, the stand was >100 years old and had experienced little or no active management. During the study period, stands were thinned to reduce fire risk, and most jack pine were cut; three plots fell in a control area with no logging. Bird communities and vegetation were sampled repeatedly before and after management activities. Subsequent to the study period, a managed burn affected much of the study area.

本数据集涵盖美国密歇根州马凯特县一处干旱生境中的杰克松（jack pine）纯林及红松（red pine）-杰克松混交林的繁殖季鸟类群落调查相关数据。研究团队于2014至2018年间，对由45个研究样地构成的样地网络内的鸟类出现情况开展了重复调查；此外，数据集还包含2013至2017年间在同一批样地采集的植被调查数据。本研究启动之初，该林分树龄已逾百年，且几乎未接受过人工经营干预。研究实施阶段，林分被实施疏伐以降低火灾风险，多数杰克松被采伐；其中3个样地处于未开展采伐作业的对照区域。研究人员在经营活动前后对鸟类群落与植被进行了多次重复采样。研究周期结束后，一场计划性火烧（managed burn）波及了研究区域的大部分范围。
