Maple Syrup Producers of the Lake States, USA: Attitudes Towards and Adaptation to Social, Ecological, and Climate Conditions
Maple syrup is an important non-timber forest product derived from the sap of the sugar maple (Acer saccharum Marshall). However, maple syrup producers are facing a diversity of challenges, including: potential range shifts in the maple resource; increasing variability in the timing, duration and yield of sap flow and syrup operations; invasive species, pests and diseases; and intergenerational land and business transfer challenges. Members of Maple Syrup Producer Associations in Minnesota, Wisconsin, and Michigan were surveyed to learn about their operations, adaptation strategies, concerns, and information needs.
Asian Longhorned Beetle
This presentation by Tim Barwise (MA-DCR) the 2018 Vermont Maple Conferences covers the current infestation and the USDA-APHIS response to asian longhorned beetle (Anoplophora glabripennis) in the greater Worcester, MA area.
The complex relationship between climate and sugar maple health: Climate change implications in Vermont for a key northern hardwood species
This study compared 141 ecologically relevant climate metrics to field assessments of sugar maple (Acer saccharum Marsh.) canopy condition across Vermont, USA from 1988 to 2012. After removing the influence of disturbance events during this time period to isolate the impact of climate, we identified five climate metrics that were significantly related to sugar maple crown condition. While three of these are monthly summary metrics commonly used in climate analyses (minimum April, August and October temperatures), two are novel metrics designed to capture extreme climate events (periods of unusual warmth in January and August). The proportion of climate-driven variability in canopy condition is comparable to the proportion accounted for by defoliating pests and other disturbance events.
Do Invasive Worms Threaten Northeast Maple Forests?
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.
