The study was carried out in Wakayama Experimental Forest of Hokkaido University in Wakayaina prefecture, to improve the habitat of wildlife, those are mainly sika deer and Japanese serow. 5 lots(0.02ha each) were clear cut in wide artificial forests of Japanese cedar and cypress. to expect the natural regenerations of broad leaved trees as feeding site for wildlife. The vegetation research was done in each plots in 1996.12, 1997.11.1998.6 and 1998.11 also established another clear cut plot which was situated next to the natural broad leaved forest and the size is more bigger(0.25ha) in 1996. The number of species those invaded to the after clear cut area were not increased so much in wide artificial forest. It seemed though some species those prefer sunshine were invaded, but some species were died because of big change of light condition. The number of invaded individuals of tree were depended on plots, in some plots it increased and in some plots it decreased. Those were because some species (for example Callicarpa japonica) were eaten by deer and serow. There had been no deer feeding signs in this forest before the clear cut plots were established. This shows such a small clear cut patch began to have a value of feeding site for wildlife. But animal feeding pressure was high from the beginning of tree invasion, so certain protection step until trees grow enough to become free from shoot damage (for example the deer fence), is necessary, In the plot next to the natural forest, we enclosed some areas, the number of tree invasion and growth of those trees in such enclosures were higher than another area.

该研究是在Wakayaina县北海道大学的Wakayama实验森林进行的，以改善野生动植物的栖息地，主要是Sika Deer和Japanese Serow。在日本雪松和赛普拉斯的宽阔的人造森林中，有5个批次（每个0.02公顷）被清除。期望宽阔的树木的自然再生是野生动植物的饲养场。植被研究是在1996.12、1997.1998.6和1998.11的1996.12、11.11.11.11.11中进行的，这也建立了另一个透明的剪切地块，该地块位于自然的宽带森林旁边，1996年的大小更大（0.25公顷）。在售后切割面积的物种的数量并没有增加如此之多的物种，这在广阔的人工森林中并没有增加。尽管有些物种偏爱阳光被侵入，但由于光明的变化很大，有些物种死亡。入侵的树木的数量取决于图，在某些地块中增加了，在某些地块中，它减少了。这些是因为一些物种（例如Callicarpa Japonica）被Deer和Serow食用。在建立透明切割地块之前，这森林中没有鹿的喂食标志。这表明如此小的透明贴片开始具有野生动植物的饲养场价值。但是，从树木入侵的开始开始，动物的喂养压力很高，因此在天然林旁边的地块中，必须进行某些保护步骤，直到树木长大到足以摆脱射击损害（例如鹿栅栏），我们封闭了一些区域，这些树木在此类外壳中的树木入侵和生长的数量比另一个区域更高。
