W~LCOX, D. A. 1986. The effects of deicing salts on vegetation in Pinhook Bog, Indiana. Can. J. Bot. 64: [865][866][867][868][869][870][871][872][873][874].A 4-year study identified the effects of road salt contamination on the vegetation of Pinhook Bog after operation of an uncovered salt storage pile adjacent to the bog for 10 years. Nearly all of the endemic plant species (excluding moat species) were absent from the portion of the bog where mean salt concentrations as high as 468 mglL sodium and 1215 mg1L chloride were measured in the interstitial waters of the peat mat. Skeletons of dead tamaracks remained. The impacted area was invaded by nonbog species and dominated by Typha angustifolia. As salt concentrations decreased by over 50% in 4 years, many of the endemic bog plants, including Sphagnum, returned to the impacted area. Declines were noted in the abundance of some of the invading species, while others continued expansion. Many of the invading and reestablished bog plants are known to be both salt tolerant and pioneers in secondary succession of disturbed bogs. WILCOX, D. A. 1986.

“…In particular, seedling damage would be high under the current deicing salt loading rates on the mountain, especially at areas close to the road. Plantresponse would be species dependent (Lumis et al, 1976;Townsend & Kwolek, 1987) with Woods rose demonstrating greater tolerance than Gambel oak which demonstrated greater tolerance than aspen. In both oak and Woods' rose, decreased leaf weight, delay in bud break (Roth & Wall, 1976) and a decline in leaf level spad measurements were observed as levels of stress increased, suggesting that such parameters would be worthy to monitor in the field.…”

“…In the greenhouse experiment, we analyzed only the leaf tissue, but we recognize that roots and shoots would also accumulate ions that could possibly shift fundamental relationships between ions in the leaf tissue. We also only sampled at the final harvest but realizethat the concentrations of many ions will vary over time (Lumis et al, 1976). In Table 6, we evaluated the relationships between %ions in the leaf tissue and also the total ion accumulation (mg) in the leaves at harvest.…”

Deicing salts applied to mountain roads during winter periods provide safe driving conditions but these salts are eventually displaced to roadside areas where they can negatively impact soils, vegetation and water resources. The aim of this study was to confirm the linkage between deicing salt applications and salt accumulation in plants and salt accumulation in soils as a function of distance from roads. We also wantedto determine whether altering the deicing salt composition would lead to a more favorable plant response. In the Mt. Charleston area of southern Nevada, NaCl was applied by the State Department of Transportation in excess of 200 tons per State Highway during the winter prior to this study. Salts sampled with depth and distance from the roads at 15 locations revealed significantly higher salinity levels (p < 0.05) at the 1 m vs. 5 and 10 m distances, with electrical conductivities as high as 37 dSm -1. In Ponderosa pine, Na and Cl concentrations were found to be elevated in needles revealing visual damage, whereas K concentrations were found to be significantly lower in damaged tissue (p < 0.05), resulting in Na/K ratios as high as 300 to 1. In a companion study we investigated the physiological response of 2 year old seedlings of aspen, Gambel oak and Woods' rose, to different salt loading rates comprised of different mixes of salts (MgSO 4 , CaCl 2 or KCl) at different %NaCl composition (100, 90, 75 and 50%). As the MgSO 4 in the salt mix increased, sulfate concentration increased in the leaves of oak (r = 0.73, p < 0.001), reflecting the shift from Cl to SO 4 availability. The % SO 4 in the leaves of oak revealed a strong linear relationship (r = 0.83 p < 0.001) with leaf weight at final harvest, as well as higher chlorophyll (spad) measurements relative to control (r = 0.89 p < 0.01) and an earlier breaking of dormancy (r = 0.65, p < 0.01), as seedlings with 2.5% SO 4 in leaves at harvest broke dormancy 10 days sooner than those oak seedlings with only 1% SO 4 in the tissue. Based on results of this study , we believe a 25% substitution of MgSO 4 would be worthy of further field evaluations as a significant decline in leaf tissue Na andCl occurred at this level, while concentrations of Ca and SO 4 increased.

“…Aufgrund seiner Schnellwüchsigkeit, standörtlichen Anspruchslosigkeit und Toleranz gegenüber anthropogenen Umwelteinflüssen wurde der Eschenahorn bald auch in Europa als Straßenbaum und für Windschutzpflanzungen beliebt. Interessanterweise gilt A. negundo jedoch als empfindlich gegenüber Streusalz (Lumis et al 1976). Die Frosthärte wird wesentlich von der ursprünglichen Provenienz bestimmt.…”
