“…Wetlands occupy about 5% of the vegetative cover types and are generally found at lower elevations. Many areas of the region have undergone cutting, and/or experienced catastrophic blowdowns, severe fires and various pests (Driscoll et al, 1991).…”

“…The Adirondack region of New York is a large forested area (2 400 000 ha) with about 2800 lakes (>2000 m 2 surface area) and many streams (Driscoll et al, 1991). The area receives high rates of acidic deposition (wet SO 4 2 deposition of ¾8 kg ha 1 year 1 (as sulphur); wet NO 3 deposition of ¾5 kg ha 1 year 1 (as nitrogen)) with a spatial pattern of decreasing deposition from the southwest to northeast (Driscoll et al, 1991;Ito et al, 2002). About 27% of the lakes in the region were found to be acidic (ANC < 0 µeq l 1 ; Driscoll et al, 1998).…”

Abstract:PnET-BGC is an integrated biogeochemical model formulated to simulate the response of soil and surface waters in northern forest ecosystems to changes in atmospheric deposition and land disturbances. In this study, the model was applied to five intensive study sites in the Adirondack and Catskill regions of New York. Four were in the Adirondacks: Constable Pond, an acid-sensitive watershed; Arbutus Pond, a relatively insensitive watershed; West Pond, an acidsensitive watershed with extensive wetland coverage; and Willy's Pond, an acid-sensitive watershed with a mature forest. The fifth was Catskills: Biscuit Brook, an acid-sensitive watershed. Results indicated model-simulated surface water chemistry generally agreed with the measured data at all five sites. Model-simulated internal fluxes of major elements at the Arbutus watershed compared well with previously published measured values. In addition, based on the simulated fluxes, element and acid neutralizing capacity (ANC) budgets were developed for each site. Sulphur budgets at each site indicated little retention of inputs of sulphur. The sites also showed considerable variability in retention of NO 3 . Land-disturbance history and in-lake processes were found to be important in regulating the output of NO 3 via surface waters. Deposition inputs of base cations were generally similar at these sites. Various rates of base cation outputs reflected differences in rates of base cation supply at these sites. Atmospheric deposition was found to be the largest source of acidity, and cation exchange, mineral weathering and in-lake processes served as sources of ANC.

“…Surface waters in the Adirondack Mountains in New York State, such as seepage and drainage lakes with thin glacial till in surrounding watersheds, are sensitive to atmospheric deposition of acid anions due to low acid neutralizing capacity (ANC; Driscoll et al, 1991Driscoll et al, , 1998. Although significant declines in SO 4 2 , NO 3 and Cl concentration in deposition have occurred in the region with correlated declines in lake water SO 4 2 , the ANC of many surface waters has not increased (Driscoll et al, 1998).…”

Abstract:This study examined differences in nitrogen solutes and groundwater flow patterns between a riparian wetland dominated by the N 2 -fixing shrub, Alnus incana ssp. rugosa, and an upstream coniferous forested riparian wetland along a stream of the Adirondack Mountains, where some surface waters are susceptible to nitrogen excess. Channel water NO 3 was up to 16 µmol l 1 greater in the alder reach, with peaks following maxima in groundwater dissolved inorganic nitrogen (DIN). NO 3 at 25 cm depth was 30 µmol greater in the alder than in the conifer reach in April, and 24 µmol l 1 greater than channel water and 30 µmol l 1 greater than that of 125 cm groundwater in June. Dissolved organic nitrogen and NH 4 C concentrations increased between 25 and 75 cm depths in both wetlands during the growing season. Inorganic nitrogen increased between the hillslope and stream in both wetlands, with the greatest increases in the alder reach during the dormant season. Greatest subsurface DIN (120 µmol l 1 ) occurred at 75 cm in the alder reach, within 1 m of the stream, between November (120 µmol l 1 NH 4 C ) and a January thaw (60 µmol l 1 each of NH 4 C and NO 3 ). Concentrations of deeper groundwater at 125 cm during this period were lower (10-30 µmol l 1 ). Lateral flow from the stream channel occurred in the alder reach during the dormant season, and channel water contribution to groundwater was correlated strongly to NO 3 at 25 cm. These results indicate that nitrification is stimulated in the presence of alders and oxidized exchange flow, producing NO 3 that may contribute to elevated channel water NO 3 during periods of peak flow.

“…Stream and lake nitrate concentrations are generally consistent with this pattern of nitrogen deposition with decreasing values from west to east across New York and New England . Grass Pond watershed, located within the southwestern Adirondack Mountains region of New York, receives some of the highest rates of acidic deposition in the region (Driscoll et al, 1991Ito et al, 2002). Despite receiving similar rates of acidic deposition, subwatersheds within Grass Pond watershed differentially neutralize acidic surface waters (Ito et al, 2007).…”

Abstract. Grass Pond watershed is located within the southwestern Adirondack Mountain region of New York State, USA. This region receives some of the highest rates of acidic deposition in North America and is particularly sensitive to acidic inputs due to many of its soils having shallow depths and being generally base poor. Differences in soil chemistry and tree species between seven subwatersheds were examined in relation to acid-base characteristics of the seven major streams that drain into Grass Pond. Mineral soil pH, stream water BCS (base-cation surplus) and pH exhibited a positive correlation with sugar maple basal area (p = 0.055; 0.48 and 0.39, respectively). Black cherry basal area was inversely correlated with stream water BCS, ANC (acid neutralizing capacity) c and NO − 3 (p = 0.23; 0.24 and 0.20, respectively). Sugar maple basal areas were positively associated with watershed characteristics associated with the neutralization of atmospheric acidic inputs while in contrast, black cherry basal areas showed opposite relationships to these same watershed characteristics. Canonical correspondence analysis indicated that black cherry had a distinctive relationship with forest floor chemistry apart from the other tree species, specifically a strong positive association with forest floor NH 4 , while sugar maple had a distinctive relationship with stream chemistry variables, specifically a strong positive association with stream water ANC c , BCS and pH. Our results provide evidence that sugar maple is acid-intolerant or calciphilic tree species and also demonstrate that black cherry is likely an acid-tolerant tree species.
