Through the increased combustion of fossil fuels, humans have dramatically increased pollutant additions of sulfur and nitrogen into the atmosphere wher eit combines with water to form sulfuric and nitric acids, creating acid rain. This article investigates the impact of this issue on sugarbush health.
Severe and extreme weather has significant impacts on sugar maples. This article discusses how to look for signs of stress, and how to manage sugarbushes for resilience.
Slides from a presentation on how sugar maples adapt to drought and other effects of climate change.
Climate change trends, the impact on maple syrup production, and mitigation strategies.
Maple producers benefit from spending time, and maybe some money, ensuring they have a healthy and productive sugarbush.
In order to survive, trees must overcome their injuries. But technically they donÕt heal their wounds, at least not the way that human and animal bodies repair, restore, or replace damaged cells or tissue. Trees are built in layers of cells that are bound by rigid walls in a modular, compartmented way. This structure dictates their wound response.
Knowing when, where, and how to tap is critical to making good maple syrup and keeping trees healthy.
Summaries of research presentations at the 2014 annual NAMSC meeting.
Knowing how to properly maintain your sugar bush — a maple producer’s most valuable resource — is a critical skill.
Acid deposition induced losses of calcium (Ca) from northeastern forests have had negative effects on forest health for decades, including the mobilization of potentially phytotoxic aluminum (Al) from soils. To evaluate the impact of changes in Ca and Al availability on sugar maple (Acer saccharum Marsh.) and American beech (Fagus grandifolia Ehrh.) growth and forest composition following a major ice storm in 1998, we measured xylem annual increment, foliar cation concentrations, American beech root sprouting, and tree mortality at the Hubbard Brook Experimental Forest (Thornton, New Hampshire) in control plots and in plots amended with Ca or Al (treated plots) beginning in 1995.
