Abstract Several organizations run wildlife-gardening programs designed to mitigate the biodiversity loss and disconnect between humans and wildlife that commonly accompanies urbanization. The National Audubon Society runs the Plants for Birds and the Humminbirds at Home programs that, like others, recommend homeowners to establish diverse assemblages of native plants with supplemental feeders. Here, we use plant and hummingbird data from the Hummingbirds at Home program to determine whether common wildlife-gardening recommendations correlate with intended outcomes. Our results showed that, after statistically controlling for several variables related to observer effort and geography, the relative occurrence and relative frequency of hummingbird sightings during patch surveys was positively related to the (1) presence of hummingbird feeders in a patch, (2) number of nectar-provisioning flowering-plant taxa in a patch, (3) degree to which nectar-provisioning flowering-plants in a patch were endemic to the conterminous USA, and (4) lack of impervious surface (a common proxy for urban development) in the surrounding landscape. These results support previous studies that showed how recommendations from wildlife-gardening programs associate with intended outcomes, but do so across an exceptionally broad, national extent that varies enormously in physical and biological geography.

在家中与蜂鸟互动:与补充喂养、植物多样性、植物起源和景观环境的关联

摘要 一些组织开展了野生动物园艺计划,旨在减轻城市化过程中常见的生物多样性丧失和人类与野生动物之间的脱节。国家奥杜邦协会运行“鸟类植物”和“蜂鸟在家”计划,与其他计划一样,该计划建议房主建立具有补充饲养者的多种本地植物组合。在这里,我们使用蜂鸟在家计划中的植物和蜂鸟数据来确定常见的野生动物园艺建议是否与预期结果相关。我们的结果表明,在对与观察者努力和地理相关的几个变量进行统计控制后,斑块调查期间蜂鸟目击的相对发生率和相对频率与以下因素呈正相关:(1)斑块中蜂鸟饲养者的存在,(2)斑块中提供花蜜的开花植物类群的数量,(3)一片片中提供花蜜的开花植物是美国本土特有的,并且 (4) 周围景观中缺乏不透水表面(城市发展的常见代表)。这些结果支持先前的研究,这些研究表明野生动物园艺计划的建议如何与预期结果相关联,但这样做的范围非常广泛,在自然和生物地理方面差异巨大的国家范围内。(3) 提供花蜜的开花植物在美国本土特有的程度,以及 (4) 周围景观中缺乏不透水表面(城市发展的常见代表)。这些结果支持先前的研究,这些研究表明野生动物园艺计划的建议如何与预期结果相关联,但这样做的范围非常广泛,在自然和生物地理方面差异巨大的国家范围内。(3) 提供花蜜的开花植物在美国本土特有的程度,以及 (4) 周围景观中缺乏不透水表面(城市发展的常见代表)。这些结果支持先前的研究,这些研究表明野生动物园艺计划的建议如何与预期结果相关联,但这样做的范围非常广泛,在自然和生物地理方面差异巨大的国家范围内。
