Response of birds to mixed forests structure

We compared bird diversity and abundance between protected natural and managed forests representing temperate mixed forests of Central Europe dominated by beech, spruce, and fir. The bird census was performed in 2021 and 2022 using the point-count method at 173 census points (88 in strictly protected areas; 85 in commercial forests) along with habitat surveys focused on potentially most important habitat variables that influence habitat selection of birds.本研究对比了以山毛榉、云杉和冷杉为优势种的中欧温带混交林内，严格保护天然林与商业经营林之间的鸟类多样性与种群丰度差异。研究于2021年和2022年实施鸟类普查，采用点计数法（point-count method）在173个普查样点开展工作，其中严格保护区域内样点88个，商品林内样点85个；同步开展生境调查，聚焦于影响鸟类生境选择的潜在关键生境变量。
