Betula ermanii range-wide provenance trial: Survival, height, diameter, and productivity data

Understanding the response of Betula ermanii populations to climate change is crucial for conservation efforts. Range-wide provenance trials provide valuable insights into local adaptation and phenotypic plasticity, aiding in the maintenance of productivity in boreal and alpine forest ecosystems. This study aimed to evaluate the impact of climate change on survival and productivity of B. ermanii, and to formulate conservation strategies for future climates. Using survival and growth data from provenance trials, models were developed and applied to projected climate scenarios obtained from WorldClim. Results indicated that populations at the southern edge and thermal limit experienced more pronounced declines in survival and productivity compared to others. Particularly, the southern-edge population struggled to survive in situ under severe climate warming, while the high-altitude edge population faced challenges in surviving ex situ. These findings emphasize the necessity of integrating..., Betula ermanii, a wind-pollinated deciduous tree species, is a significant component of Japan's deciduous broad-leaved forests, particularly prevalent in subalpine regions and forest margins, where it often forms pure forests. Seeds of B. ermanii were gathered during the autumns of 2016 and 2017 from 11 natural populations across its distribution zones. These seeds were grown in the nursery at the University of Tokyo Hokkaido Forest (UTHF) in April 2018. Following two growing seasons, containerized saplings were planted at 11 sites across Japan in autumn 2019 and spring 2020. Each planting site received 20 seedlings per population, with exceptions for Akkeshi (AKS), Goyo-San (GYS), and Choukai-San (CKS). This endeavor resulted in a total of 2013 seedlings (183 seedlings × 11 planting sites). Random planting designs were implemented for each site to mitigate spatial autocorrelation issues. Survival counts, height, and diameter measurements were conducted in autumn from 2020 to 2023.
