Gastropod abundance at Hubbard Brook Experimental Forest, Watershed 1 and West of Watershed 6, 1997-2006

Snail and slug abundance were measured for a 10 year period between 1997 - 2006 at three elevations on Watershed 1 as well as in a reference area west of Watershed 6. Watershed 1 received calcium additions as wollastonite (CaSiO3) during the study period. This data set includes counts of snails and and slugs for the entire study period. These data were gathered as part of the Hubbard Brook Ecosystem Study (HBES). The HBES is a collaborative effort at the Hubbard Brook Experimental Forest, which is operated and maintained by the USDA Forest Service, Northern Research Station.本数据集针对1997年至2006年共10年的监测时段，于流域1（Watershed 1）的三个海拔梯度区域，以及流域6（Watershed 6）西侧的参照区域内，测定了蜗牛与蛞蝓的丰度。研究期间，流域1施加了以硅灰石（wollastonite，CaSiO₃）为载体的钙添加处理。本数据集涵盖了整个研究周期内的蜗牛与蛞蝓计数数据。这些数据为哈伯德布鲁克生态系统研究（Hubbard Brook Ecosystem Study, HBES）的采集成果之一。该研究是在哈伯德布鲁克实验林（Hubbard Brook Experimental Forest）开展的协作项目，而该实验林由美国农业部林务局北方研究站（USDA Forest Service, Northern Research Station）运营维护。
