Last year’s prolonged dry spell in certain areas of New Brunswick led to a decline in groundwater levels, raising concerns among maple syrup producers about the impact on the upcoming harvest season. The reduced rainfall and higher temperatures in 2025 resulted in wells and streams drying up.
David Briggs, the owner of Briggs Maples in Hillsborough, explained that diminished groundwater and sunlight can hinder photosynthesis in maple trees, potentially leading to decreased sap production. However, he noted that warmer weather can stimulate sugar production in trees, possibly resulting in sweeter sap this year.
Despite these variables, predicting the exact sap yield remains challenging. Briggs emphasized the impossibility of visually estimating the sap output of a tree, expressing hope for future scientific advancements in this area.
Local residents faced water scarcity issues, with some wells running dry in 2025. Briggs speculated that his maple farm might encounter similar groundwater challenges, although confirming the situation is difficult.
Briggs highlighted the significance of the freeze-thaw cycle in sap flow, noting the inconsistent temperatures attributed to climate change. He observed a trend of milder winters and winter warm spells affecting sap flow and ultimately yield.
The changing seasons have also altered the traditional tapping time for maple trees, with harvesting now commencing as early as February compared to the typical start in March. Jane Scott, co-owner of Dumfries Maples near Nackawic, echoed concerns about declining stream levels and the potential impact on the maple season due to the summer’s low water levels.
Having harvested maple for over two decades, Scott acknowledged the evolving season patterns and uncertainty surrounding the drought’s influence on this year’s crop, hoping for a positive outcome.
The adaptation to these environmental shifts includes preparing tapping equipment early to coincide with temperature fluctuations. As the maple syrup season approaches, producers like Briggs and Scott remain vigilant, anticipating the challenges and opportunities brought forth by changing climatic conditions.
