Last year, drought conditions in certain areas of New Brunswick led to a decline in groundwater levels, causing concern among maple harvesters about the potential impact on this year’s yield. The 2025 weather patterns, characterized by reduced rainfall and higher temperatures, resulted in wells and streams drying up.
David Briggs, the owner of Briggs Maples in Hillsborough, noted that decreased groundwater and sunlight can hinder photosynthesis in maple trees, leading to lower sap production. However, he mentioned that heat can boost sugar production in trees, potentially resulting in sweeter sap this year. Despite these factors, predicting the exact outcome for the season remains challenging.
Briggs emphasized the difficulty in estimating sap production by looking at trees, expressing hope for future scientific advancements in this regard. In 2025, residents in his area had to drill deeper wells due to water shortages, indicating a potential impact on groundwater levels at his maple farm.
Briggs explained that sap flow relies on the freeze-thaw cycle, but inconsistent temperatures due to climate change have disrupted this process. He observed milder winters and winter warm spells, affecting sap flow and yield. The changing seasons have also altered the timing of tapping maple trees, with harvesting beginning as early as mid-February instead of March, necessitating proactive preparation.
Jane Scott, co-owner of Dumfries Maples near Nackawic, mentioned a significant decrease in water levels in streams at her farm last summer. She expressed concerns about the potential effects on the upcoming maple season, highlighting the need to wait until the end of the season to assess the impact of the drought on their crop.
