Last year, drought conditions in parts of New Brunswick led to a depletion of groundwater levels, raising concerns among maple harvesters about the potential impact on this year’s yield. The lack of rain and higher temperatures in 2025 resulted in many wells and streams drying up.
David Briggs, the owner of Briggs Maples in Hillsborough, highlighted the correlation between reduced groundwater and sunlight affecting photosynthesis in maple trees, leading to decreased sap production. Despite the potential for sweeter sap due to increased sunlight, the overall yield may be lower due to the limited rainfall.
Briggs emphasized the complexity of factors influencing sap production, noting the unpredictability of a tree’s output. He mentioned the challenges posed by fluctuating temperatures caused by climate change, affecting the freeze-thaw cycle crucial for sap flow.
There have been observations of milder winters and early warm spells, altering the traditional tapping season for maple trees. Harvesting now begins as early as mid-February, a significant shift from the previous start time in March, in response to changing weather patterns.
Jane Scott, co-owner of Dumfries Maples near Nackawic, experienced a noticeable decrease in water levels in streams at her farm last summer. Concerns arose regarding the potential impact on the upcoming maple season, with the uncertainty of how the drought might affect the crop.
As a seasoned maple harvester for over 25 years, Scott acknowledged the evolving nature of the maple season and the need to assess the drought’s impact at the season’s end. The hope is that the drought will not have a detrimental effect on this year’s maple harvest.
