With the accelerating pace of global change, it is imperative that we obtain rapid inventories of the status and distribution of wildlife for ecological inferences and conservation planning. To address this challenge, we launched the SNAPSHOT USA project, a collaborative survey of terrestrial wildlife populations using camera traps across the United States. For our first annual survey, we compiled data across all 50 states during a 14-week period (17 August-24 November of 2019). We sampled wildlife at 1,509 camera trap sites from 110 camera trap arrays covering 12 different ecoregions across four development zones. This effort resulted in 166,036 unique detections of 83 species of mammals and 17 species of birds. All images were processed through the Smithsonian's eMammal camera trap data repository and included an expert review phase to ensure taxonomic accuracy of data, resulting in each picture being reviewed at least twice. The results represent a timely and standardized camera trap survey of the United States. All of the 2019 survey data are made available herein. We are currently repeating surveys in fall 2020, opening up the opportunity to other institutions and cooperators to expand coverage of all the urban-wild gradients and ecophysiographic regions of the country. Future data will be available as the database is updated at eMammal.si.edu/snapshot-usa, as will future data paper submissions. These data will be useful for local and macroecological research including the examination of community assembly, effects of environmental and anthropogenic landscape variables, effects of fragmentation and extinction debt dynamics, as well as species-specific population dynamics and conservation action plans.

随着全球变化步伐的加快，我们必须快速获取野生动物的现状和分布信息，以便进行生态推断和保护规划。为了应对这一挑战，我们启动了 SNAPSHOT USA 项目，这是一个使用相机陷阱在美国各地对陆地野生动物种群进行合作调查的项目。在我们的第一次年度调查中，我们在 14 周的时间内（2019 年 8 月 17 日至 11 月 24 日）汇总了全美 50 个州的数据。我们在 12 个不同生态区的 4 个发展区的 110 个相机陷阱阵中的 1509 个相机陷阱地点对野生动物进行了抽样调查。这一努力产生了 166,036 个独特的哺乳动物 83 种和鸟类 17 种的检测结果。所有图像都通过史密森尼的 eMammal 相机陷阱数据存储库进行处理，并包括一个专家审查阶段，以确保数据的分类学准确性，从而确保每张图片至少审查两次。结果代表了对美国的一次及时和标准化的相机陷阱调查。所有 2019 年的调查数据都可在此处获得。我们目前正在 2020 年秋季重复调查，为其他机构和合作者提供扩大覆盖全国城市-野生梯度和生态地理区域的机会。未来的数据将随着数据库在 eMammal.si.edu/snapshot-usa 上的更新而提供，未来的数据论文提交也将提供。这些数据将有助于地方和宏观生态研究，包括检查群落组装、环境和人为景观变量的影响、破碎化和灭绝债务动态的影响，以及特定物种的种群动态和保护行动计划。没有版权限制；在使用数据发表文章时，请引用本文。
