GCE-LTER Hammock Well Vegetation and Invertebrate Monitoring - January 2012

In July 2008 the GCE LTER program selected two hammocks for intensive study: HN_i_1 and PC_i_29. HN_i_1 is of Holocene origin and is located adjacent to Blackbeard Island to the north of Sapelo Island, Georgia. PC_i_29 is also of Holocene origin and is located adjacent to the south end of Sapelo Island. These hammocks are of similar size, with similar vegetation zones in the high marsh environment. Groundwater well transects were established that run from the upland, through the marsh, and up and over the upland area of each hammock. Two permanent plots were established at each well in order to characterize the plant and invertebrate diversity and abundance by surveying plots once a year. This data set includes the results of January 2012 monitoring studies.2008年7月，GCE LTER长期生态研究项目选取了两处盐沼高地丘（hammocks）开展深入研究，编号分别为HN_i_1与PC_i_29。其中HN_i_1形成于全新世（Holocene），坐落于佐治亚州萨佩洛岛以北的黑胡子岛附近区域；PC_i_29同样形成于全新世（Holocene），位置紧邻萨佩洛岛南端。这两处盐沼高地丘尺寸相近，所处高盐沼（high marsh）环境中拥有相似的植被带。研究人员布设了地下水井样带（groundwater well transects），每条样带均从高地出发，穿过盐沼，再延伸并覆盖每处盐沼高地丘的高地区域。每口地下水井处均设置了两个永久样地，通过每年一次的样地调查，对植物与无脊椎动物（invertebrate）的多样性及种群丰度进行表征分析。本数据集涵盖2012年1月的监测研究成果。
