研究将气候变化与加拿大关键的圣诞树Balsam Firs(Balsam firs)的衰落联系起来。 Study links climate change to decline of balsam firs, a key Christmas tree in Canada.

新不伦瑞克大学最近的一项研究将气候变化(特别是干旱和热量)与加拿大流行的圣诞树Balsam Firs的衰落联系起来。 A recent study from the University of New Brunswick links climate change, specifically drought and heat, to the decline of balsam firs, a popular Christmas tree in Canada. 这项发表在《森林前沿与全球变化》（Frontiers in Forests and Global Change）上的研究发现，香脂冷杉特别容易受到这些条件的影响，在未来 25 到 50 年内，它们的数量可能会下降。 The research, published in "Frontiers in Forests and Global Change," found that balsam firs are particularly vulnerable to these conditions, with a potential decline in their numbers over the next 25 to 50 years. 这项研究强调需要种植多种树种并监测天气模式,以加强森林的复原力。 The study highlights the need for planting diverse tree species and monitoring weather patterns to enhance forest resilience. Balsam Firs约占新不伦瑞克省树木的20%, 该省95%以上的圣诞树都是balsam Firs, Balsam firs account for about 20% of New Brunswick's trees, and over 95% of the province's Christmas trees are balsam firs, with many being exported to the U.S.
