Couvert végétal au sein et près de bassins drainés à Old Crow Flats, Yukon, Canada

From August 25 to September 1, 2022, fieldwork was conducted in Old Crow Flats, Yukon (Canada) to study thermokarst lake and drained basin dynamics. As part of this work, percentage cover estimates of the vegetation were made at 10 sites located near or in drained basins; this publication presents the data. Each vegetation survey was done with five 1m by 1m quadrats along north-south and east-west axes (centered on one of the quadrats), at 15 m intervals. The vegetation was then classified into functional groups and the average height of each group was also measured. Active layer depth measurements are available in a NordicanaD publication by Turner et al. (2022).

2022年8月25日至9月1日，研究团队于加拿大育空地区的旧克劳平原（Old Crow Flats）开展野外考察，以研究热融湖（thermokarst lake）与疏干盆地的动态变化。作为本次考察的组成部分，研究团队在10个位于疏干盆地附近或内部的样地开展了植被盖度估算工作，本数据集即收录该部分观测数据。每处植被调查均以1个样方为中心，沿南北、东西方向轴，以15米为间距设置5个1米×1米的样方（quadrats）。随后将观测到的植被划分为不同功能群，并测定各功能群的平均高度。活动层厚度（active layer depth）的相关测量数据可参见Turner等人2022年发表于《NordicanaD》的学术论文。
