Forest Inventory of a Whole Tree Harvest 1982-2009: Watershed 5, Hubbard Brook Experimental Forest

A whole-tree harvest was conducted during the dormant season of 1983-1984 in order to assess ecosystem response to whole-tree logging operations. Pre-harvest forest inventory surveys were conducted in 1982 on the whole of the watershed. Post-harvest surveys were conducted in 1990, 1994 and every 5 years thereafter. Sampling methods change overtime so users should be aware of these changes when looking to aggregate data. Pre-treatment sampling included all stems >=2cm, post treatment measurements in 1990 were conducted using circular plots, 1995 to 2005 where conducted within a subset of the 25x25m grid cells on 1x25m square plots, and the final measurement 2009 included nested circular plots
