Phenological stages of sedges were observed at a long term experimental moist tussock tundra site and a long-term experimental wet sedge tundra sites (Arctic LTER) for 1996 near Toolik Lake, AK.

Phenological stages of sedges were observed at a long term experimental moist tussock tundra site and a long-term experimental wet sedge tundra sites near Toolik Lake, AK. Also, ITEX maximum growth measurements were recorded on August 19th (moist tussock tundra). Experimental treatments at each site included factorial NxP, greenhouse and shadehouse and were begun in 1989. See 96gsphdc.html and 96gsphsg.html for phenological data on deciduous and evergeen species.科研人员在阿拉斯加州（AK）图利克湖附近的长期实验性湿润草丛冻土带样地与长期实验性湿地莎草冻土带样地中，开展了莎草科植物的物候期观测。此外，科研人员于8月19日针对湿润草丛冻土带样地完成了国际冻土实验计划（ITEX）的最大生长量测定。两处样地均设置了氮磷双因子析因处理、温室栽培与遮棚处理，相关实验于1989年正式启动。有关落叶物种与常绿物种的物候数据，可参阅96gsphdc.html与96gsphsg.html文件。
