Abstract

This study focuses on the natural regeneration of Nothofagus glauca, a critical component of temperate forests in the Mediterranean region of the Southern Hemisphere in Chile. Various harvesting and canopy opening methods were evaluated to understand their impact on the regeneration of this species. A “mast seeding” behavior was observed in seed production, with alternating years of high and low production. Seed viability was affected by lepidopteran infestation and extreme weather events. The results indicate variable seed quantity and quality, influencing regeneration. First-year seedling mortality was significant, reaching up to 95%, and regeneration decreased annually. Additionally, changes in canopy opening and solar radiation transmission were analyzed, revealing significant post-harvest modifications. This study provides valuable insights for the sustainable management of Mediterranean forests, emphasizing the importance of considering seed production variability and regeneration dynamics in decision-making processes.
造林处理对 Nothofagus glauca 森林树冠结构模式、太阳辐射传输和树木再生的影响
这项研究的重点是智利南半球地中海地区温带森林的重要组成部分 Nothofagus glauca 的自然再生。研究评估了各种采伐和树冠开放方法,以了解它们对该树种再生的影响。在种子生产中观察到了 "桅杆播种 "行为,高产和低产年份交替出现。种子活力受到鳞翅目害虫和极端天气事件的影响。结果表明,种子数量和质量的变化会影响再生。第一年幼苗死亡率很高,高达 95%,再生率逐年下降。此外,还分析了树冠开度和太阳辐射传输的变化,揭示了采收后的显著变化。这项研究为地中海森林的可持续管理提供了宝贵的见解,强调了在决策过程中考虑种子生产的可变性和再生动态的重要性。
