近年来，人们对传粉昆虫数量下降的担忧不断增加，但由于缺乏空间和时间上的数据，检测传粉昆虫群落丰度、分类丰富度和组成变化的能力受到严重阻碍。公民科学家也许能够扩大授粉监测计划的空间和时间范围。我们开发了一个公民科学监测协议，在该协议中，我们培训了13名公民科学家，以观察和分类花游客在订单或超级家庭的决议（e。例如，在一个实施例中，蜜蜂，黄蜂，苍蝇）和蜜蜂（蜜蜂总科）内的分辨率更高。我们通过比较公民科学家（观察数据集）和专业人员（基于数据集）在17个站点同时收集的数据来评估该协议。不同的网站的存在和年龄的绿篱种植，以改善传粉者的栖息地质量。我们发现显着的，正相关的两个数据集之间的更高层次的分类组成，蜜蜂（意大利蜜蜂）的丰度，非蜜蜂的蜜蜂丰度，蜜蜂丰富度，蜜蜂群落相似性。这两个数据集的结果也显示出类似的趋势（或缺乏），在这些指标不同的存在和年龄的树篱网站。然而，公民科学家没有观察到专业科学家在同一地点收集的大约一半的蜂群。因此，公民科学观测数据的效用可能仅限于检测社区一级在空间和时间上的丰度、丰富度或相似性的变化，公民科学观测可能无法可靠地反映特定传粉者物种或群体的丰度或出现频率。
Concerns about pollinator declines have grown in recent years, yet the ability to detect changes in abundance, taxonomic richness, and composition of pollinator communities is hampered severely by the lack of data over space and time. Citizen scientists may be able to extend the spatial and temporal extent of pollinator monitoring programs. We developed a citizen-science monitoring protocol in which we trained 13 citizen scientists to observe and classify floral visitors at the resolution of orders or super families (e. g., bee, wasp, fly) and at finer resolution within bees (superfamily Apoidea) only. We evaluated the protocol by comparing data collected simultaneously at 17 sites by citizen scientists (observational data set) and by professionals (specimen-based data set). The sites differed with respect to the presence and age of hedgerows planted to improve habitat quality for pollinators. We found significant, positive correlations among the two data sets for higher level taxonomic composition, honey bee (Apis mellifera) abundance, non-Apis bee abundance, bee richness, and bee community similarity. Results for both data sets also showed similar trends (or lack thereof) in these metrics among sites differing in the presence and age of hedgerows. Nevertheless, citizen scientists did not observe approximately half of the bee groups collected by professional scientists at the same sites. Thus, the utility of citizen-science observational data may be restricted to detection of community-level changes in abundance, richness, or similarity over space and time, and citizen-science observations may not reliably reflect the abundance or frequency of occurrence of specific pollinator species or groups.
