Lake Sediment Pollen from Knob Hill Pond in Marshfield VT from 13924 BP to Present
Aim We analyzed a dataset composed of multiple palaeoclimate and lake-sediment pollen records from New England to explore how postglacial changes in the composition and spatial patterns of vegetation were controlled by regional-scale climate change, a subregional environmental gradient, and landscape-scale variations in soil characteristics. Location The 120,000-km2 study area includes parts of Vermont and New Hampshire in the north, where sites are 150-200 km from the Atlantic Ocean, and spans the coastline from southeastern New York to Cape Cod and the adjacent islands, including Block Island, the Elizabeth Islands, Nantucket, and Martha’s Vineyard. Results Boreal forest featuring Picea and Pinus banksiana was present across the region when conditions were cool and dry 14,000-12,000 calibrated 14C yrs before present (ybp). Pinus strobus became regionally dominant as temperatures increased between 12,000 and 10,000 ybp. The composition of forests in inland and coastal areas diverged in response to further warming after 10,000 ybp, when Quercus and Pinus rigida expanded across southern New England, while conditions remained cool enough in inland areas to maintain Pinus strobus. Increasing precipitation allowed Tsuga canadensis, Fagus grandifolia, and Betula to replace Pinus strobus in inland areas during 9000-8000 ybp, and also led to the expansion of Carya across the coastal part of the region beginning at 7000-6000 ybp. Abrupt cooling at 5500-5000 ybp caused sharp declines in Tsuga in inland areas and Quercus at some coastal sites, and the populations of those taxa remained low until they recovered around 3000 ybp in response to rising precipitation. Throughout most of the Holocene, sites underlain by sandy glacial deposits were occupied by Pinus rigida and Quercus. Main conclusions Postglacial changes in the composition and spatial pattern of New England forests were controlled by long-term trends and abrupt shifts in temperature and precipitation, as well as by
Lake Sediment Pollen from Knob Hill Pond in Marshfield VT from 14000 BP to Present
The abrupt, range-wide decline of Tsuga canadensis ~5500 calibrated years before present (cal. yr BP) is one of the most-studied events in North American paleoecology. Little attention, however, has been given to an earlier Tsuga decline, dated to ~6000 cal. yr BP in southern Ontario, Canada. To investigate whether this event occurred elsewhere in eastern North America, we analyzed the middle-Holocene interval of a lake-sediment record from Knob Hill Pond, located in northern Vermont, USA, an area of historically high Tsuga abundance. A dramatic, short-lived drop in Tsuga pollen abundance does occur at ~6000 cal. yr BP in the Knob Hill Pond record, indicating that Tsuga populations declined in various parts of its range. We hypothesize that both middle-Holocene declines of Tsuga were caused by the deleterious effects of pronounced droughts on this moisture-sensitive tree. Close examination of pollen data from a transect of sites across New England reveals that the earlier decline of Tsuga is present in other records, although some aspects of the event appear to have varied geographically. While northern and higher-elevation sites exhibit a nearly full recovery of Tsuga populations between the two declines, records further to the south are characterized by a stair-step pattern of progressive decline. At sites near its southern range limit, relatively warm conditions between ~6000 and 5500 cal. yr BP were apparently not conducive to the reestablishment and survival of Tsuga, and thus it was unable to recover between the drought events.

Red spruce foliar nutritional and metabolic responses to N, Ca, and N+Ca additions in a plot level study from Hubbard Brook Experimental Forest NH, Adirondack State Park, NY and Groton State Forest, VT from 1997-2000.
Plot Level Ca, N, Ca+N Study Background: Three mature red spruce (Picea rubens Sarg.) – balsam fir (Abies balsamea (L.) Mill.) stands with closed canopies from across the northeastern United States were selected to assess the effects of N and Ca additions on forest growth. These sites included Groton, VT (Groton State Forest), Big Moose Lake, NY (Adirondack State Park) and Watershed 9 in the Hubbard Brook Experimental Forest, NH. Site descriptions can be found in the pdf file included in this dataset. Full site descriptions have been published in Kulmatiski et al, 2007, Nitrogen and calcium additions increase forest growth in northeastern USA spruce–fir forests, Canadian Journal of Forest Research 37: 1574-1585. This publication also provides more in-depth site and soil descriptions. In 1992, three replicate 30 m by 30 m plots were randomly assigned to each of four treatment levels: control (control), Ca addition (Ca), N addition (N), or Ca + N addition (Ca + N) in NY and NH (for a total of 12 plots at each site). In VT, only control and Ca treatments were established due to limited space and research goals (for a total of 6 plots). Beginning in July 1992 through July 2000, N amendments (100 kilograms of NH4NO3-N per hectare per year), Ca amendments (80 kilograms of CaSO4-Ca plus 80 kilograms of CaCl2-Ca per hectare per year), and Ca + N (same dosage as separate applications) amendments were hand broadcast as commercial grade salts. Applications were made in June, July, and August to each plot in each year. SUMMARY: The main objectives of this study were to evaluate changes over time (1997-2000) in foliar metabolism of mature red spruce (Picea rubens Sarg.) trees in response to additions of nitrogen, Ca, or N +Ca supplementation. N was applied as NH4NO3 and Ca was applied as gypsum [CaSO4 .2H2O (2X) + CaCl2 .2H2O (1X)] and Ca + N treatment was a combination of both at the same concentrations Three sites received these treatments; Groton, VT (Groton State Forest), Bi
