North Temperate Lakes LTER: Macrophyte Transects - Trout Lake 1982 - current

These data are collected to document and characterize the submersed macrophytes of Trout Lake to evaluate the long-term stability of this component and to interface with investigations of other compartments of the ecosystem. Four sites along the shoreline of Trout Lake have been sampled annually in August along permanent line transects. This dataset includes species presence/absence and transect summary data by depth along the transect. This information is useful in determining the annual variability of the submersed macrophytes and providing information on the effects of the invasion of an introduced crayfish Sampling Frequency: annually during summer Number of sites: 4

本数据集旨在记录并表征特劳特湖（Trout Lake）的沉水水生植物（submersed macrophytes），以评估该生态组分的长期稳定性，并衔接该生态系统其他组分的相关调查研究。研究团队沿特劳特湖岸线布设4个采样点，于每年8月沿永久样线（line transect）进行年度采样。本数据集包含各深度梯度下的物种存在/缺失数据，以及对应样线的汇总统计数据。该数据集可用于分析沉水水生植物的年际变化规律，并为评估外来入侵螯虾的生态影响提供数据支撑。采样频率：每年夏季（8月）；采样点数量：4个。
