Last year, certain areas of New Brunswick experienced a decrease in groundwater levels due to drought conditions, leading to concerns among maple harvesters regarding the potential impact on this year’s yield. The combination of reduced rainfall and higher temperatures in 2025 resulted in the drying up of numerous wells and streams.
David Briggs, the owner of Briggs Maples in Hillsborough, explained that lower groundwater levels and sunlight exposure can hinder photosynthesis in maple trees, ultimately leading to decreased sap production. However, he noted that the heat can also contribute to increased sugar production in the trees.
Briggs expressed uncertainty about the upcoming season, mentioning that while the increased sunlight may result in sweeter sap, the lack of rainfall could lead to a reduced yield. Assessing the sap production of trees remains challenging, and Briggs highlighted the unpredictability of determining a tree’s performance each year.
Notably, individuals in the region had to drill deeper wells or faced dry wells in 2025. Briggs speculated that a similar situation might occur at his maple farm, but verification is currently unavailable. He emphasized the impact of fluctuating temperatures due to climate change on the sap flow process, mentioning the observed trend of milder winters and winter warm spells.
The shifting seasons have altered the timing of tapping maple trees, with harvesting now commencing as early as mid-February compared to the traditional start in March. Jane Scott, co-owner of Dumfries Maples near Nackawic, shared concerns about the decreased water levels in streams at her farm, questioning the potential repercussions for the upcoming maple season.
Having been involved in maple harvesting for over 25 years, Scott acknowledged the changing season patterns and expressed hopes that the drought’s effects on the crop would be minimal. The true impact will only be evident at the end of the season, she added.
