There has been limited research investigating summer habitat use of bats in managed forests in the northeastern United States. Consequently, there is limited knowledge to inform forest managers seeking to maintain or enhance bat habitat, particularly for several federally threatened, endangered, or candidate species. In summer 2017–2018, we conducted repeated acoustic surveys to determine what forest characteristics are associated with bat habitat use in managed forests in the Adirondack region of upstate New York. We modeled detection corrected probability of occupancy for bats in three phonic groups: high, mid, and low frequency. Across all phonic groups, probability of occupancy increased with decreasing canopy cover. High-, mid-, and low-frequency bats were more likely to use recently harvested sites (<10 years since harvest). High-frequency bats also used mature stands. Midfrequency bats demonstrated a preference for further distances from forest roads, whereas low-frequency bats preferred areas with a higher percentage of clutter. Our results suggest that tending and regenerating even-aged forest management practices can provide habitat for foraging bats in the Adirondacks.

东北经营林夏季蝙蝠栖息地利用和森林特征

在美国东北部的管理森林中，对蝙蝠的夏季栖息地使用进行调查的研究有限。因此，对于寻求维持或改善蝙蝠栖息地的森林管理者来说，知之甚少，特别是对于几个联邦受威胁、濒危或候选物种。在 2017-2018 年夏季，我们进行了反复的声学调查，以确定哪些森林特征与纽约州北部阿迪朗达克地区管理森林中蝙蝠栖息地的使用相关。我们对三个语音组中蝙蝠的检测校正概率进行建模：高频、中频和低频。在所有语音组中，占用概率随着树冠覆盖率的降低而增加。高频、中频和低频蝙蝠更有可能使用最近收获的地点（收获后不到 10 年）。高频蝙蝠也使用成熟的支架。中频蝙蝠表现出偏爱距离森林道路较远的地方，而低频蝙蝠则偏爱杂物百分比较高的区域。我们的研究结果表明，照料和再生均匀年龄的森林管理实践可以为阿迪朗达克山脉的觅食蝙蝠提供栖息地。
