Bats have important ecological roles in ecosystems, but many species are threatened because of anthropogenic impacts. Tanzania has limited information on how bats respond to habitat modification. This makes it difficult to anticipate which bat species are at risk. Bat activity and species richness were assessed in five land‐use types: forest and banana–coffee (upland habitats), rice paddy, riverine and sisal estate (lowland habitats). Mist nets, harp traps and bat detectors were used to sample bats. Species richness differed between habitats. Bat activity levels were higher in lowland habitats than upland habitats. Riverine and rice paddy habitats were shown to have an important role as foraging sites for many insectivorous bats as bat species richness and activity were generally higher than other habitats. Fruit‐eating bats preferred riverine and banana–coffee habitats. We recommend using organic manure as alternatives to chemical fertilisers, and pesticide use should be avoided in rice paddies. Riparian vegetation along rivers and water bodies should be maintained as important faunal nesting, roosting and/or foraging grounds. The requirement that farming practices be at least 60 m from the river should be strictly enforced. These recommendations will help in the conservation of bats and their habitats in modified agricultural landscapes.

坦桑尼亚乔姆自然森林保护区及其周围地区不同土地利用类型的蝙蝠活动和物种丰富度

蝙蝠在生态系统中具有重要的生态作用，但由于人类活动的影响，许多物种受到威胁。坦桑尼亚关于蝙蝠如何对生境变化做出反应的信息有限。这使得很难预测哪些蝙蝠物种处于危险之中。在五种土地利用类型中评估了蝙蝠的活动和物种丰富度：森林和香蕉咖啡（高地栖息地），稻田，河流和剑麻（低地栖息地）。薄雾网，竖琴陷阱和蝙蝠探测器用于对蝙蝠进行采样。不同生境的物种丰富度不同。低地栖息地的蝙蝠活动水平高于高地栖息地。由于许多蝙蝠的物种丰富度和活动性普遍高于其他生境，因此河川和稻田生境在许多食虫蝙蝠的觅食场所中起着重要作用。吃水果的蝙蝠更喜欢河边和香蕉咖啡的栖息地。我们建议使用有机肥料替代化肥，在稻田中应避免使用农药。沿河和水体的河岸植被应作为重要的动物区系，栖息地和/或觅食地加以维护。严格执行距河至少60 m的耕作规定。这些建议将有助于保护蝙蝠及其在经过改良的农业景观中的栖息地。严格执行距河至少60 m的耕作规定。这些建议将有助于保护蝙蝠及其在经过改良的农业景观中的栖息地。严格执行距河至少60 m的耕作规定。这些建议将有助于在经过改良的农业景观中保护蝙蝠及其栖息地。
