Title:

Biomass accumulation in trees and downed wood at Bartlett Experimental Forest, Hubbard Brook Experimental Forest, the Bowl Natural Research Area, and the White Mountain National Forest, NH, USA

Alternate Identifier:

DOI PLACE HOLDER

Abstract:

Standing trees and downed wood were inventoried in all of the chronosequence stands in the White Mountains, New Hampshire to characterize biomass. Live and standing dead trees were inventoried in the chronosequence stands in 1994, 2004, 2012, and 2021. Coarse (≥ 7.6 cm diameter) and fine woody debris (3.0 – 7.6 cm) were inventoried at the same stands in 2004 and 2020. Twigs (FWD < 3.0 cm) were inventoried in 2004 and 2020. The Bowl and Mt. Pond old-growth sites were inventoried (standing trees and downed wood) in 2021.

Description:

The chronosequence consisted of 16 northern hardwood stands. Six stands were located in Bartlett Experimental Forest (BEF), one in Hubbard Brook Experimental Forest (HBEF), and seven in the surrounding WMNF for a total of 14 successional stands. The two old-growth stands were The Bowl Research Natural Area (RNA) in Grafton County, NH and Mountain Pond, a proposed RNA in Chatham, Carroll County, NH.

Live and standing dead trees were inventoried in the successional stands in 1994, 2004, 2012, and 2021. The 1994 inventories were conducted in all of the successional stands, with the exception of CC2-1989. Stand CC2-1989 was first inventoried in 2004. Hence, four inventories were conducted in all 14 of the successional stands except CC2-1989 which had three inventories. In 2021 The Bowl and Mountain Pond were also sampled.

Five belt transects were used for tree inventory in all 16 stands. In most of the stands, the transects were 50 m long. In two stands, transects were shorter to fit within the area with a uniform disturbance history. In the two old-growth stands, the transects were 70.7 m long to accommodate higher spatial variation in these stands. In all of these stands we identified and measured all live and standing dead trees ≥ 10.0 cm dbh within 5.0 m of either side of the transect. Standing trees were included in the inventory if they were leaning at an angle < 45° from vertical. Two of the stands (H1-1939 and CC2-1989) were smaller, requiring transects 30 m long with tree inventory conducted within 2.5 m of the transects.

Standing tree biomass was calculated from the dbh of both live and dead trees using species-specific allometric equations developed at Hubbard Brook by Whittaker et al. (1974) with modifications by Siccama et al (1994) for sugar maple, striped maple (Acer pensylvanicum L.), yellow birch, American beech, and red spruce (Picea rubens Sarg.). These equations described most of the species we encountered, and the remaining species were estimated using substitutions common to biomass calculations at Hubbard Brook (Whittaker et al. 1974).

For the purpose of this study, downed woody debris (DWD) is separated into twigs, fine

woody debris (FWD), and coarse woody debris (CWD). We define twigs as FWD < 3.0 cm diameter, not including any portion buried by leaf litter. Fine woody debris is DWD ≥ 3.0 cm but < 7.6 cm, and CWD is DWD ≥ 7.6 cm diameter and at least 1 m in length. FWD and CWD were sampled in the successional stands in 2004, and twigs were sampled in 2006. Twigs, FWD, and CWD were re-sampled in 2020 using the same methods employed in 2004 and 2006. Stand H1-1939 was sampled in 2004 and 2006 but was not re-sampled in 2020 due to recent installation of a fence that produced DWD not representative of an even-aged stand last managed in 1939. Fine and coarse woody debris were inventoried at the old-growth stands in 2021. Twig sampling was prohibited in the two old-growth stands because the sampling methods are destructive.

Fine and coarse woody debris were surveyed with the line intersect sampling method

(LIS). In each stand, we established three permanent clusters, each composed of three 25-m transects separated by 120° diverging from a randomly placed center point, monumented with a 1 m tall fiberglass post. The clusters were randomly oriented in the stands, with the constraint that they not overlap. In two stands alternative transect layouts were used for LIS sampling due to stand size limitations (CC2-1989) or to avoid a skid trail (T20-1958). Illustrations of the LIS transects were made in google drawings and are published as the pdf file “Chronosequence_DWD_LIS_transect_design.pdf”.

Exact clusters and azimuths were re-surveyed in 2020 whenever possible. If a center

monument could not be relocated, its location was approximated based on hand-drawn maps created in 2004. Four clusters, rather than the usual three, were used in the two old-growth stands because they were expected to be more heterogeneous.

From the center point outward, we recorded FWD from 5 to 10 m and CWD from 5 to 25 m. Thus, total transect lengths were 45 m for FWD and 180 m for CWD in every stand where standard clusters were used. We followed the USFS Forest Inventory and Analysis protocol and included FWD or CWD in sampling if it was the target size at the point of intersection with the transect, at least 1 m long, and at least partially above the soil surface. We also included debris if it was above the soil surface but leaning at an angle < 45° from the ground. To be counted, debris had to intersect the transect through the central axis of the piece. If a piece of debris was fractured and would pull apart easily at the intersection with the transect, we counted it as two pieces, if not, we counted it as. We included debris if it retained enough structure to differentiate the sample from surrounding forest soil. We did not include heavily decomposed debris that had lost all original shape and form such that it could not be picked up without crumbling into pieces <3.0 cm.

We identified the species when possible and decay class (1 - least decayed, 5 - most

decayed) of all debris intersected on the transects. If debris was unidentifiable to species due to advanced stages of decomposition, we identified debris to genus or at least a classification of gymnosperm or angiosperm. We recorded the length of each piece, the diameter at intersection, and the small-end and large-end diameters. We took all diameter measurements perpendicular to the length of the wood sample.

Coarse woody debris density was measured in 2004 by collecting samples from the first

piece of CWD of each species and decay class combination encountered along each transect. Samples were collected by cutting a disc ~ 5 to 10 cm thick with a bow saw or chainsaw. Each CWD sample was vacuum-sealed and frozen. Volume was measured by water displacement with a correction of 30 mL to account for the volume of the vacuum bag, based on tests of the volume of sealed and unsealed objects. The wood samples were subsequently dried at 60 ℃ to constant mass and weighed. The fresh volume and dry mass were used to calculate wood density. Samples were ground and analyzed for chemical composition (not reported here). The volume and dry mass were used to calculate wood density. The average density of wood of each species and decay class was used in calculation. For the 8 combinations of species and decay class that were not found during 2004 inventories, we used densities from a national database (Harmon et al. 2008).

We sampled twigs from five 4-m² subplots per site. We rejected subplots if they occurred on ephemeral or perennial streams, which can redistribute these size classes of dead wood. We randomly placed each plot based on a stratified design utilizing permanently marked inventory transect. The twig sample plots were not identical for 2006 and 2020. In each subplot established for twig sampling, we collected every part of twigs and branches 16-30 mm in diameter. We cut twigs with pruning shears where the diameter was > 30 mm, or where the debris crossed the subplot boundary. We collected twigs < 16 mm in nested 0.5-m² subplots in the same manner. We also collected dead branches not attached to trees suspended up to 2.5 m above the ground. We did not collect dead branches attached to living or dead trees, unless the tree was dead and leaning at an angle < 45° from the forest floor. We also did not include twigs that were covered by leaf litter. Twigs were separated into size classes ≤ 7.5 mm, 7.5 mm-16 mm, and 16-30 mm, then oven dried at 60℃ to constant mass.
