Oregon Spotted Frog Monitoring in the Oregon Cascades 2012-2016

This dataset contains information from visual encounter surveys conducted between 2012 and 2016 by USGS as part of an ongoing Oregon spotted frog (Rana pretiosa) monitoring effort in the Oregon Cascade Mountain Range. We surveyed 91 sites using a rotating frame design in the Klamath and Deschutes Basins, Oregon, which encompass most of the species' core extant range. Data consist of spotted frog counts aggregated by date, location, and life stage, as well as data on environmental conditions at the time of each survey.本数据集收录了2012至2016年间由美国地质调查局（USGS）开展的视觉偶遇调查法（visual encounter surveys）相关数据，该工作是俄勒冈喀斯喀特山脉内针对俄勒冈斑蛙（Rana pretiosa）的长期监测项目的一部分。本次调查在俄勒冈州克拉马斯（Klamath）与德舒特（Deschutes）盆地内设置91个样点，采用轮换样框设计开展工作，该区域覆盖了该物种现存核心分布范围的绝大部分。数据集包含按调查日期、采样点位及生活史阶段汇总的斑蛙数量统计数据，同时涵盖每次调查时记录的环境条件相关信息。
