Last year, drought conditions in parts of New Brunswick led to a depletion of groundwater levels, causing concern among maple harvesters for the upcoming season. The lack of rainfall and higher temperatures in 2025 resulted in many wells and streams drying up.
David Briggs, the owner of Briggs Maples in Hillsborough, explained that reduced groundwater and sunlight could mean less photosynthesis for his maple trees, leading to decreased sap production. However, he noted that the heat could also aid in producing more sugar in the trees.
Briggs expressed uncertainty about what to expect for this season, mentioning the complexity of various factors influencing sap production. He highlighted the unpredictability of determining the amount of sap a tree will yield and speculated that future scientific advancements might provide more insight into this process.
In response to the drought, some individuals in the area had to deepen their wells, with some wells running dry in 2025. Briggs acknowledged the possibility of a similar impact on the groundwater level at his maple farm but emphasized the lack of a definitive confirmation.
He elaborated on how trees release sap through pressure generated by the freeze-thaw cycle, noting the inconsistent temperatures due to climate change. Briggs observed milder winters and warm spells during winter, which he believed would affect sap flow and yield.
The changing seasons have also altered the timing of tapping maple trees, with harvesting now starting in mid- or early February instead of the traditional March timeframe. Briggs emphasized the need to prepare early for tapping as temperatures rise.
Jane Scott, co-owner of Dumfries Maples near Nackawic, shared concerns about reduced water levels in some streams at her farm following a summer with unusually low water levels. She reflected on the potential impact of the drought on the upcoming maple season, underscoring the uncertainty until the end of the season.
Both Briggs and Scott highlighted the evolving challenges faced by maple harvesters due to shifting environmental conditions, emphasizing the need for adaptation and vigilance in managing maple production.
