在1992年和1993年，我们调查了蝙蝠物种的觅食和喂养活动与宽带蝙蝠探测器在2个树叶高度在4个年龄级的北方硬木和云杉/冷杉林的立场在白色山国家森林，新罕布什尔州和缅因州。蝙蝠活动的关联与步道和水体和海拔的影响进行了测量。雾网，竖琴陷阱，超声波探测器被用来建立物种的存在。蝙蝠活动集中在步道和水体边缘，并在同一采样高度的林分内是均匀的。在森林中，蝙蝠活动是最高的过成熟（>119年，平均蝙蝠活动/夜的35%）硬木林和再生（0-9年）的两种森林类型的立场（平均蝙蝠活动/夜的26%）。被捕获的蝙蝠大多数（56%）是成年雄性小棕蝠（鼠耳蝠lucifugus）。我们的数据表明，矩阵的森林类型和年龄组，包括再生（皆伐和组伐）和过熟硬木，结合步道和水体，有助于满足蝙蝠在白色山国家森林的夏季栖息地的要求。
In 1992 and 1993, we surveyed the foraging and feeding activity of bat species with broadband bat detectors at 2 foliage heights in 4 age classes of northern hardwood and spruce/fir forest stands in White Mountain National Forest, New Hampshire and Maine. The association of bat activity with trails and water bodies and the effect of elevation were measured. Mist nets, a harp trap, and ultrasonic detectors were used to establish species presence. Bat activity was concentrated at trail and water body edges and was uniform within a forest stand at the same sampling height. Within the forest, bat activity was highest in overmature (>119 yr, 35% of mean bat activity/night) hardwood stands and in regenerating (0-9 yr) stands of both forest types (26% of mean bat activity/night). The majority of bats trapped (56%) were adult male little brown bat (Myotis lucifugus). Our data indicate that a matrix of forest types and age classes including areas of regeneration (clearcuts and group cuts) and overmature hardwood, in combination with trails and water bodies, help fulfill the summer habitat requirements of bats in White Mountain National Forest.
