Breeding bird counts around Toolik Field Station, Alaska (2010-2024)

The Toolik Field Station Bird Monitoring Program was established in 2008 to monitor long term trends in arrival, departure, status and abundance of all birds breeding within the Toolik-centric region. Transects through the commonly occurring habitats were established. The overall protocol was adopted from the Alaska Landbird Monitoring Survey (http://www.absc.usgs.gov/research/bpif/Monitor/alms2.html). These data are from the bird count surveys in 2010-2024. The point count locations are situated 500 m apart, ten minutes are spent at each point count location and all birds seen and heard are recorded. The number of points within each transect was determined based on the natural features of the landscape. The data collected from these transects will be used to determine status and abundance of birds that breed in the Toolik area. The survey points are to be walked starting from the field station and moving away from the camp pad. Transects are marked on the map. The distances recorded from 2010-2011 were intervals; from 2012 onward, the distances recorded are actual distances.

图利克野外站鸟类监测计划（Toolik Field Station Bird Monitoring Program）于2008年设立，旨在监测以图利克为核心的区域内所有繁殖鸟类的抵达、离去、种群状况及种群丰富度的长期变化趋势。现已布设覆盖典型生境的样线（transect），该监测方案整体沿用自阿拉斯加陆地鸟类监测调查（Alaska Landbird Monitoring Survey，http://www.absc.usgs.gov/research/bpif/Monitor/alms2.html）。本数据集的数据来源于2010至2024年开展的鸟类计数调查。样点计数（point count）点位间距为500米，每个点位需耗时10分钟，记录所有可见及可闻的鸟类。每条样线内的样点数量依据区域自然地貌特征确定。本次样线采集的数据将用于分析图利克区域繁殖鸟类的种群状况与丰富度。调查样点的行进路线需从野外站出发，向远离营地场地的方向行进。样线已在地图上完成标注。2010至2011年记录的距离为间隔距离；2012年起，记录的距离为实际实测距离。
