Soil base saturation combines with Beech Bark Disease to influence composition and structure of Sugar Maple-Beech forests in an acid rain-impacted region Soil base saturation combines with Beech Bark Disease to influence composition and structure of Sugar Maple-Beech forests in an acid rain-impacted region
Sugar maple, an abundant and highly valued tree species in eastern North America, has experienced decline from soil calcium (Ca) depletion by acidic deposition, while beech, which often coexists with sugar maple, has been afflicted with beech bark disease (BBD) over the same period. To investigate how variations in soil base saturation combine with effects of BBD in influencing stand...

Modeled effects of soil acidification on long-term ecological and economic outcomes for managed forests in the Adirondack region (USA) Modeled effects of soil acidification on long-term ecological and economic outcomes for managed forests in the Adirondack region (USA)
Sugar maple (Acer saccharum) is among the most ecologically and economically important tree species in North America, and its growth and regeneration is often the focus of silvicultural practices in northern hardwood forests. A key stressor for sugar maple (SM) is acid rain, which depletes base cations from poorly-buffered forest soils and has been associated with much lower SM vigor...

A new look at liming as an approach to accelerate recovery from acidic deposition effects A new look at liming as an approach to accelerate recovery from acidic deposition effects
Acidic deposition caused by fossil fuel combustion has degraded aquatic and terrestrial ecosystems in North America for over four decades. The only management option other than emissions reductions for combating the effects of acidic deposition has been the application of lime to neutralize acidity after it has been deposited on the landscape. For this reason, liming has been a part of...

Can the eastern red-backed salamander (Plethodon cinereus) persist in an acidified landscape? Can the eastern red-backed salamander (Plethodon cinereus) persist in an acidified landscape?
Hardwood forests of eastern North America have experienced decades of acidic deposition, leading to soil acidification where base cation supply was insufficient to neutralize acid inputs. Negative impacts of soil acidity on amphibians include disrupted embryonic development, lower growth rates, and habitat loss. However, some amphibians exhibit intraspecific variation in acid tolerance...

Application of lime (CaCO3) to promote forest recovery from severe acidification increases potential for earthworm invasion Application of lime (CaCO3) to promote forest recovery from severe acidification increases potential for earthworm invasion
The application of lime (calcium carbonate) may be a cost-effective strategy to promote forest ecosystem recovery from acid impairment, under contemporary low levels of acidic deposition. However, liming acidified soils may create more suitable habitat for invasive earthworms that cause significant damage to forest floor communities and may disrupt ecosystem processes. We investigated...
