随着全球变化步伐的加快，我们必须迅速获得野生动物的状况和分布的生态推理和保护规划的库存。为了应对这一挑战，我们启动了SNAPSHOT USA项目，这是一项在美国使用相机陷阱对陆地野生动物种群进行的合作调查。对于我们的第一次年度调查，我们在14周内（2019年8月17日至11月24日）收集了所有50个州的数据。我们从110个相机陷阱阵列中的1,509个相机陷阱站点对野生动物进行了采样，这些相机陷阱阵列覆盖了四个开发区的12个不同生态区。这一努力导致了83种哺乳动物和17种鸟类的166，036次独特检测。所有图像均通过史密森尼电子哺乳动物相机陷阱数据库进行处理，并包括专家审查阶段，以确保数据的分类准确性，从而使每张图片至少审查两次。这些结果代表了美国及时和标准化的相机陷阱调查。所有2019年的调查数据都在这里提供。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机会，扩大对该国所有城市-野生梯度和生态生理区域的覆盖范围。随着数据库在eMammal.si.edu/snapshot-usa上更新，未来的数据将可用，未来的数据文件提交也将如此。这些数据将是有用的地方和宏观生态研究，包括检查社区集会，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，以及物种特定的人口动态和保护行动计划。没有版权限制;请在使用数据发表时引用本文。
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.
