Fine root biogenic silica in sugar maple trees (Acer saccharum) on soil freezing and control plots at the Hubbard Brook Experimental Forest

This dataset presents biogenic silica (BSi) concentrations in sugar maple (Acer saccharum) fine roots collected from a snow manipulation experiment at Hubbard Brook Experimental Forest (New Hampshire, USA). BSi data are reported as percent dry biomass. The samples were collected from control and treatment plots in April 2009, May 2009, and April through July 2010. 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.
