本研究调查了历史普查数据，以评估北方日本主要高树种对强风的脆弱性。在1954年一场严重台风过后，立即收集了密集的数据，测量了超过500公顷天然混交林中超过20，000棵受损树木（定义为死亡或失去主树冠的树木）。一半以上的受损树木已被连根拔起，并发现整个物种的连根拔起的比例的负尺寸依赖。简单的相关性分析的平均物种特异性的特征表明，高冠深/高度的树种往往连根拔起（对干断裂）在一个大小级的直径在胸高30-50厘米。虽然普查数据没有得到关于未受损害树木的信息，但对受干扰前的林分的估计（根据63个1公顷的地块数据以及航空照片和地理信息系统）表明，观察到的损害达到约100万公顷。25%的面积。受损树木的比例似乎是物种之间的两倍（15-42%的断面积）。更高比例的连根拔起，这表明大量供应的小费了土丘，和不太脆弱的物种的混合物，可能有助于恢复过程后，在这种类型的混交林风干扰。
This study examined historical census data to evaluate the vulnerability of major tall-tree species in northern Japan to strong winds. Intensive data, which measured more than 20,000 damaged trees (defined as trees that were killed or lost their major crown) in >500 ha of a natural mixed forest, were collected immediately after a severe typhoon in 1954. More than half of the damaged trees had been uprooted, and the negative size-dependency was found for the proportion of uprooting throughout species. Simple correlation analyses with respect to the averaged species-specific characteristics suggested that tree species with a high crown-depth/height tended to uproot (against to stem breakage) in a size-class with diameter at breast height 30–50 cm. Although the census data had yielded no information about non-damaged trees, the estimation of pre-disturbed stand (based on 63 1-ha plot data together with aerial photographs and GIS) revealed that the observed damage reached ca. 25% in terms of basal area. The proportion of damaged trees seemed to be doubled among species (15–42% in basal area). A higher proportion of uprooting, which indicates a large supply of tip-up mounds, and mixture of less vulnerable species, might contribute to recovery process after a wind disturbance in this type of mixed forests.
