Balsam fir trees in New Brunswick are exhibiting a concerning trend of turning red and perishing following last year’s exceptionally dry summer, prompting worries about the fate of this iconic provincial tree. Professor Anthony Taylor, a forestry researcher at the University of New Brunswick, has received reports from woodlot owners and witnessed the detrimental effects firsthand as the vibrant evergreens, commonly used for Christmas trees, gradually transition to a red, desiccated state before succumbing to death.

According to Taylor, the observed pattern aligns with previous instances after periods of hot and arid summers. He emphasizes that the warm, dry conditions, such as the drought experienced last year, significantly impede the balsam fir’s growth capacity. Drawing from his extensive research on climate change’s impact on the province’s forests, Taylor notes that comparable die-offs of balsam fir followed unusually hot, dry summers in 1986 and 2018.

The professor explains that under drought conditions, the trees prematurely halt the photosynthesis process, hindering their growth. This interruption results in an inadequate production of essential energy stores required for sustaining basic metabolic functions and defense mechanisms, thereby placing the trees at a disadvantage. Taylor clarifies that when a tree is already stressed by factors like insects or pathogens, the likelihood of die-off escalates due to its diminished resilience.

Additionally, balsam fir trees possess shallow roots, making it challenging for them to access water during dry spells. Peter McKeil, a woodlot owner in Burtt’s Corner, noticed the progressive reddening of his balsam firs from the lower branches upward, with new red spots emerging daily, indicating an ongoing die-off. McKeil estimates a loss of approximately 100 trees to date and has adjusted his harvesting strategies to salvage remaining healthy firs before further losses occur.

Expressing concerns about the future of balsam firs in the region, McKeil believes that with the exacerbation of climate change, the species may be doomed, particularly in southern New Brunswick. He underscores the urgency for climate action, emphasizing the need to transition away from fossil fuels and adopt sustainable forest management practices to mitigate the adverse effects of climate change on the province’s iconic tree species.

For Taylor, the sight of the red trees serves as a tangible manifestation of the detrimental impact of climate change on New Brunswick’s balsam firs. He views this phenomenon as a clear indicator of the urgent need for societal action to combat climate change and preserve the province’s natural environment. Taylor hopes that his research will continue to raise awareness and drive transformative change to safeguard the future of the balsam fir and other vulnerable species in the face of climate change challenges.
