Please see the link above & the links in the citations section for a more extensive methods descriptions. The watershed 6 in the Hubbard Brook Experimental Forest (13.23 ha), is divided in 208 25 m x 25 m plots. Trees >=2 to <=10 cm dbh were subsampled using a 3 meter wide strip along one edge of each 25 m x 25 m plot from 1992 to 2017. The lengths of these strips are not always exactly 25 meters, due to drift or imprecise replacement of the corner stakes. The actual measured length of the strip is used to calculate the area of the plot (as given in the data) for the smaller trees. All stems that met the size criteria were measured individually, and in some years it was noted whether a stem was part of a group of stems from the same tree (i.e. multiple stems that split from a single trunk below breast height). Aboveground and belowground biomass was estimated for each stem in the inventory and is included in the data. Estimates were based on species-specific allometric equations developed at Hubbard Brook.Citation(s)
