研究表明 Douglas fir 幼苗在更凉爽的气候中存活得更好 树冠覆盖了老树 Study shows Douglas fir seedlings survive better in cooler climates with older trees' canopy cover.

不列颠哥伦比亚大学的一项研究发现,在协助向更凉爽的气候迁移过程中,Douglas fir苗圃的生存可以通过在树冠覆盖较老的树木部分覆盖的地区种植来改善这些苗圃的生存。 A study from the University of British Columbia finds that the survival of Douglas fir seedlings during assisted migration to cooler climates can be improved by planting them in areas with partial canopy cover from older trees. 这一方法提供了对其生存至关重要的基本保护、营养物和水。 This method provides essential protection, nutrients, and water, crucial for their survival. 研究强调了保护老树的重要性,以帮助森林适应气候变化,因为濒临灭绝的森林可能导致碳排放增加和生物多样性丧失。 The research highlights the importance of preserving older trees to help forests adapt to climate change, as dying forests could lead to increased carbon emissions and loss of biodiversity.
