Abstract

Snow avalanches are among the most important disturbances in mountain ecosystems. The effects of avalanches on the endemic Pinus heldreichii and Pinus peuce forests in the Pirin Mountains in Bulgaria are poorly understood. These forests are among the few remaining old-growth forests with preserved natural dynamics in Europe. However, the ongoing development of tourist infrastructure at the borders of some of the best-preserved Pinus heldreichii and Pinus peuce forests close to Bansko ski resort leads to increased tourist pressure. Many backcountry skiers and snowboarders venture beyond the resort boundaries, practicing their activities in these forests and avalanche tracks and couloirs within them. The objective of our study was to collect tree-ring cores from Pinus peuce and Pinus heldreichii trees affected by avalanches and verify the specific types of damages and tree responses characteristic for the species and region. Then using the collected data, we aimed at reconstructing the years in which specific areas were affected by avalanches and in this way obtain data on the magnitude of larger events. Our study shows that large magnitude avalanches (LMA) in the vicinity of Bansko ski resort in the Pirin Mountains in Bulgaria occurred dozens of times in the 20th century. On average the period between LMAs ranged between 9 and 20 years with the shortest period between two such events in one couloir being 2 years. Avalanches affected forests high on the couloir banks and left traces in the tree rings related to the mechanical impact that snow avalanches had on the surviving trees. In the studied tree-ring cores of Pinus peuce and Pinus heldreichii the most informative types of responses were sharp growth suppressions, including missing rings, followed by reaction wood and in less cases visible scars and callus tissue. Our data for frequent large avalanches shows that is necessary to address the avalanche risk with high priority especially for the Palashica couloir, which directly threatens the lower parts of the ski runs as well as other facilities in Bansko ski resort.

通过对 Pinus peuce 和 Pinus heldriechii 树的树环分析确定保加利亚皮林丘陵雪崩的年代
雪崩是山区生态系统中最重要的干扰之一。人们对雪崩对保加利亚皮林山特有的 Pinus heldreichii 和 Pinus peuce 森林的影响知之甚少。这些森林是欧洲仅存的几片保持自然动态的古老森林之一。然而,在靠近班斯科滑雪胜地的一些保存最完好的红松和黑松林的边界地区,旅游基础设施的不断发展导致游客压力增大。许多越野滑雪者和单板滑雪者冒险越过度假村的边界,在这些森林以及森林中的雪崩路径和溪谷中进行他们的活动。我们的研究目的是收集受雪崩影响的欧洲赤松(Pinus peuce)和红松(Pinus heldreichii)的树环芯线,并验证该树种和地区特有的具体损害类型和树木反应。然后,利用收集到的数据,我们旨在重建特定地区受雪崩影响的年份,并通过这种方式获得有关较大事件严重程度的数据。我们的研究表明,在 20 世纪,保加利亚皮林山脉班斯科滑雪胜地附近发生过数十次大规模雪崩(LMA)。平均而言,两次 LMA 之间的间隔时间在 9 到 20 年之间,在一个峡谷中两次 LMA 之间的间隔时间最短为 2 年。雪崩影响了峡谷两岸高处的森林,并在树年轮中留下了雪崩对幸存树木造成的机械影响的痕迹。在所研究的欧洲赤松(Pinus peuce)和红松(Pinus heldreichii)的树环芯材中,最有参考价值的反应类型是急剧的生长抑制,包括缺环,其次是反应木,在较少情况下是明显的疤痕和茧组织。我们关于频繁发生的大型雪崩的数据表明,有必要高度重视雪崩风险,尤其是帕拉希卡峡谷的雪崩风险,因为它直接威胁到滑雪道的下部以及班斯科滑雪胜地的其他设施。
