位于日本温带地区的小川森林保护区及其附近进行的生物多样性监测计划的结果，确定了三种不同的模式的物种丰富度。该地区的森林的特点是镶嵌的二级落叶林的各种年龄分散在种植园的针叶树。物种丰富度随林龄变化的三种类型如下：1。类型Ⅰ（蝴蝶、管租蜂和黄蜂、食蚜蝇、果蝇和天牛）的物种多样性在皆伐后的开阔地最高，随着林龄的增加而降低。II型（螨与蘑菇），老看台表现出更大的多样性比年轻的看台;和，3。第三类（蛾，甲螨，弹尾虫，步甲，蚂蚁），物种的数量并没有很大的变化与林分年龄，但排序分析显示，有变化的物种组成。这些结果表明，不同年龄的林分组合，或异质排列的林分，可以有助于维持昆虫多样性的景观水平。
The results of a biodiversity monitoring program conducted in the Ogawa Forest Reserve and its vicinity, situated in a temperate region of Japan, identified three different patterns for species richness. Forests of the region are characterized by a mosaic of secondary deciduous stands of various ages scattered among plantations of conifers. The three different types of change in species richness observed in response to the stand age are as follows: 1. Type I (butterflies, tube-renting bees and wasps, hoverflies, fruit flies, and longicorn beetles), the species diversity was highest in open areas, just after clear cutting, decreasing with the stand age; 2. Type II (mites associated with mushrooms), older stands showed greater diversity than younger stands; and, 3. Type III (moths, oribatid mites, collembolas, carabid beetles, and ants), the number of species did not change greatly with the stand age, though ordination analysis revealed that there was variation in species compositions. These results indicate that combinations of stands of different ages, or heterogeneously arranged stands, can contribute to the maintenance of insect biodiversity at the landscape level.
