Aquatic plant bryophyte chemical properties (DP1.20063.001)

Aquatic plant and bryophyte clip harvest sampling is conducted once per year at aquatic sites (during the mid-summer aquatic biology window). Ten samples are collected per site if aquatic vegetation is present. In wadeable streams, clip harvest samples are collected near plant transect locations. In lakes and rivers, ten randomly selected points are sampled at depths that can be colonized by vegetation. These samples are partitioned in the domain support facility into subsamples for chemical analyses of carbon and nitrogen and shipped to an external facility.

水生植物与苔藓植物（bryophyte）剪取收获采样每年于水生样地开展一次，采样时段为仲夏水生生物监测窗口期。若样地内分布有水生植被，则每个样地采集10份样品。在可涉水溪流中，剪取收获样品采集于植物样带布设点位附近；在湖泊与河流中，则在植被可定植的水深区间内随机选取10个点位开展采样。所有样品将在区域保障实验室内分装为用于碳、氮元素化学分析的子样品，并运送至外部协作实验室完成后续分析。
