Last year’s dry spell in certain areas of New Brunswick led to a decline in groundwater levels, causing worry among maple syrup producers about the impact on this year’s harvest. The combination of reduced rainfall and higher temperatures in 2025 resulted in the drying up of many wells and streams.
David Briggs, who owns Briggs Maples in Hillsborough, explained that diminished groundwater and sunlight can hinder photosynthesis in maple trees, leading to lower sap production. However, he noted that the heat can stimulate the trees to produce more sugar, potentially resulting in sweeter sap this year. Yet, the lack of rain may offset these benefits.
Briggs emphasized the unpredictability of sap production, mentioning the challenges of determining the yield based on visual inspection of the trees. He highlighted the uncertainty surrounding the groundwater levels on his maple farm, noting similarities to the well situation in his region during the dry period.
According to Briggs, sap flow relies on the freeze-thaw cycle’s pressure mechanisms, which have been disrupted by inconsistent temperatures attributed to climate change. He observed milder winters and occasional warm spells in winter, anticipating a consequent impact on sap flow and yield.
The alterations in seasonal patterns have also influenced the timing of tapping maple trees, with harvesting commencing earlier in mid-February rather than the traditional start in March. Briggs advised being prepared to tap trees as soon as temperatures rise to optimize sap collection efficiency.
Jane Scott, co-owner of Dumfries Maples near Nackawic, echoed concerns about reduced water levels in streams at her farm due to last summer’s drought. She expressed uncertainty about the potential repercussions on the upcoming maple season, reflecting on the evolving nature of the harvesting timeline over their 25 years in the business.
Both producers will have to wait until the season’s end to assess the drought’s impact on their maple crops, maintaining hope that the adverse conditions do not significantly affect their yield.
