Some maple producers have reported low sugar maple regeneration that could be related to the presence of worms. This second wave of invasion by Asian earthworms is of concern to forest ecologists because of its potential disruption to the forest.
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 composition and structure, measurements of soils, canopy, subcanopy, and seedlings were taken in 21 watersheds in the Adirondack region of NY (USA), where sugar maple and beech were the predominant canopy species and base saturation of the upper B horizon ranged from 4.4 to 67%.
Maple Watch is studying sap to investigate environmental impacts of climate change on sugar maples.
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.
Climate change trends, the impact on maple syrup production, and mitigation strategies.
Slides from a presentation on how sugar maples adapt to drought and other effects of climate change.
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.
