2010 relative percent cover of plant species in LTER moist acidic, dry heath, and moist non-acidic tundra experimental plots; and in new experimental plots established in 2006.

In 2010, Relative percent cover of plant species was measured in the Arctic LTER's experimental and control plots across several habitats: moist acidic, dry heath, and moist non-acidic tundra; in new variable (low) nutrient addition experimental plots established in 2006; and for Sagavanirktok River toposequence plots in tussock and heath tundra.2010年，研究人员测定了北极长期生态研究站（Arctic LTER）多个生境类型下实验样地与对照样地的植物物种相对盖度，所涉及的生境包括湿润酸性苔原、干燥石楠灌丛苔原以及湿润非酸性苔原；同时针对2006年设立的低浓度养分添加实验样地（该处理为本次研究新增的变量水平）开展了相关测定；此外还涵盖了萨格瓦尼托克河（Sagavanirktok River）草丘苔原与灌丛苔原地形序列样地的测定数据。
