通过野外试验，研究了在过度拥挤的针叶树种植园迹地实施皆伐后的森林恢复模式及其影响因素。地点选择在日本西部的暖温带地区，主要是落叶阔叶次生林和广泛的针叶树种植园。在研究区皆伐13年后，自然再生的林分建立了围栏。围墙内的植被以先锋树为主，如野桐和花椒。相比之下，自然再生的立场，没有围墙有限的先锋树。在这些林分中建立了以先锋灌木（如龙牙木）为主的植被。减少冠层高度和总断面积外的植被围栏观察。站在哪里Q。在皆伐后立即种植acutissima，在有围栏和无围栏的林分中均建立了由该物种在冠层中占优势的植被。皆伐后出现的树种多为果食动物种子传播类型。然而，这项研究的结果表明，这些食果动物种子传播型树木更容易被鹿浏览比壳斗科的树木。天然林恢复后，人工林皆伐可能会受到抑制，由于鹿草食动物在相对较低的鹿密度，如果在皆伐人工林树木更新的主要来源是非壳斗科树木。
A field experiment was conducted involving deer exclosures and planting ofQuercus acutissima, a deciduous oak, to reveal forest recovery patterns and factors following clear-cutting at overcrowded conifer plantation sites. Sites were selected in a warm temperate region in western Japan, which is dominated by deciduous broad-leaved secondary forests and extensive conifer plantations. Thirteen years after clear-cutting in the study area, naturally regenerated stands were established with exclosures. The exclosures housed vegetation dominated by pioneer trees, such asMallotus japonicusorZanthoxylum ailanthoides. In contrast, naturally regenerated stands without exclosures had limited pioneer trees present. Vegetation dominated by pioneer shrubs (e.g.Aralia elata) was established in these stands. Reduced canopy height and total basal area were observed for vegetation outside the exclosures. In stands whereQ. acutissimawas planted immediately after clear-cutting, the vegetation that is dominated by this species in the canopy layer was established in both stands with and without exclosure. Most of tree species that emerged after clear-cutting across all stands were of the frugivore seed dispersal type. However, results from this study suggest that these frugivore seed dispersal type trees are more vulnerable to deer browsing than trees from the Fagaceae family. Natural forest recovery following plantation clear-cutting could be inhibited due to deer herbivory at relatively low deer density if a major source of tree regeneration in clear-cut plantations is non-Fagaceae trees.
