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.
