  • Abstract:

    Hemlock decline in New England is caused by direct and indirect effects of invasion of the hemlock woolly adelgid. Direct damage from the insect is causing gradual mortality of hemlock, and widespread harvesting of hemlock in advance of mortality, in contrast, causes immediate mortality and removal of biomass from the site. Although both processes affect thousands of acres of forest annually we have only a limited understanding of their effects on forest ecosystem function and productivity and the nature of the subsequent forest community. We anticipate that harvesting will yield different consequences than gradual mortality from the insect. Therefore we designed an experiment to simulate these contrasting impacts, by logging or girdling hemlock stands. Results from the experimental treatments are compared to the changes observed in forests that are being infested by the adelgid, and can also be included in integrated analyses of a suite of large experiments that form a core component of the Harvard Forest LTER program.

  • Methods:

    Study Design

    The study uses large plots and a Before After Control Impact (BACI) design. Plots were established and most response parameters were monitored for 1-2 growing seasons prior to the manipulations. There are two replicates of four treatments: control, hardwood control, commercial logging and girdling. In 2009, HWA was observed on trees in the experimental plots; the effects of HWA will overlay all treatments. Intensive study plots are 30 x 30 m within 90 x 90 m treatment units - that is, the center (or "core area") is surrounded by approximately one tree height of treatment area (overstory tree heights range from ~25-35m) . Intensive measurements focus on the central plots, but the buffers and outlying areas provide additional area for other studies and manipulations. Treatments include:

    1. Control plots are hemlock dominated and received no manipulation other than sampling.

    2. Hardwood Control plots simulate a likely future forest condition after hemlock woolly adelgid kills all hemlock in a stand and deciduous trees grow into the site. They received no manipulation other than sampling.

    3. Commercial Logging plots simulate an intensive commercial logging operation. Hemlock and other commercially valuable trees were removed, including larger hardwoods and pine for saw logs as well as smaller stems that a logger might take in order to improve future stand quality, facilitate skidding and general operation, or initiate a new cohort of sprouts. Two-thirds to three-fourths of the stand basal area was cut in these two plots, using hand-felling by chainsaw and skidding with a rubber-tired skidder. The intent was to generate an extreme response that is within the range of those seen on real commercial cuts. This treatment took place in Winter 2004-05.

    4. Girdling plots simulate some of the characteristics of hemlock woolly adelgid. All sizes of hemlock were girdled, resulting in gradual mortality and standing dead hemlock. No other species were girdled, and there is no further site disturbance. Important characteristics of hemlock woolly adelgid infestation missing include the very lengthy period of decline during which the plant is undergoing physiological stress and metabolic imbalance that may induce biogeochemical and microbial changes on the site. This treatment took place in late May 2005.

    Understory Vegetation Sampling

    In 2003, we established two transects running north-south through the center 30m x 30m of each plot at the Simes Tract of Harvard Forest for understory vegetation sampling. Five 1 m2 subplots were spaced evenly along each transect. We labeled the NW corner, unless otherwise marked, with an orange flag.

    We annually estimate percent cover for herbs, shrubs, and seedlings to the nearest one percent. We count the number of seedlings by species. A seedling is a tree less than 1.3m tall. If rocks, stumps, slash, standing tree bases or coarse woody debris cover more than 5% of the plot, their percent cover is recorded to the nearest 5%. In addition, the depth of the organic soil layer is measured to the nearest 0.5 cm at the NW corner of each subplot (2003, 2006 and 2016). We search each plot and compile a species list for the entire 30m x 30m area.

    Saplings were censused by species within the central 30m x 30m area of each plot prior to the treatments, and every two years thereafter. A sapling is a tree greater than 1.3m tall but less than 5cm dbh (diameter at breast height, 1.3m). In 2015, we measured sapling heights with a telescoping height pole. We measured all stems for uncommon species, and a random subsample (e.g. every 10th stem encountered) for frequent species. Stems that recruited into the greater than 5cm dbh class were tagged, measured and mapped in the 2009 and 2014 tree censuses (see HF126).
