“…Then, structural diversity maintains plant diversity (Jobidon et al 2004). Plantation management practices, such as weeding, salvage logging and thinning effectively set the plant community back to a previous stage of succession (Nagaike et al 2003) There were higher similarity between natural forest and broad-leaved plantation in woody and herbaceous species layers (63 and 50% respectively), while coniferous plantation and natural forest have the lowest similarity in woody species layer (37%). Poorbabaei and Poorrahmati (2009) considered high similarity in species composition between plantation and adjacent natural forest due to the natural forest was the main source of seed in plantation.…”

Pourbabaei H, Asgari F, Reif A, Abedi R. 2012. Effect of plantations on plant species diversity in the Darabkola, Mazandaran Province,. In this study, the effect of plantations on plant species diversity was investigated in Darabkola, Mazandaran province, north of Iran. To conduct the study, a natural mixed forest, a broad-leaved plantation (Alnus subcordata-Acer velutinum) and a coniferous plantation (Cupressus sempervirens var. horizontalis-Pinus brutia) were selected. 35 sampling plots were taken in systematic random method in each area. Data analysis was carried out using Simpson, Hill's N 2 , Shannon-Wiener and Mc Arthur's N 1 diversity indices, Smith and Wilson evenness index and species richness. Results revealed that there were 32 plant species in natural forest and 30 plant species were found in each plantation. Rosaceae and Lamiaceae were the main families in the studied areas. Diversity and evenness indices of all vegetation layers had the most values in the natural forest. Richness of woody plants had the highest value in the natural forest, while herbaceous richness was the highest in coniferous plantation. Mc Arthur's N1 had the highest value among diversity indices and followed by Hill's N 2 , Shannon-Wiener and Simpson indices, respectively. In addition, results showed that there were significant differences among diversity, evenness and richness indices in all vegetation layers in the three studied areas.

“…The SEC plots had not been recently managed. The belt-shaped plots were designed to sample the topographical variation of each forest and thus minimize variation in natural conditions among the forest types [8,16,31,32,33]. All plots were located at the center of each forest to avoid any edge effects caused by differences in neighboring forest.…”

-We compared the plant species diversity of forest-floor vegetation in long-rotation Larix kaempferi plantations with standardrotation plantations and abandoned coppice forest in central Japan. Species diversity and richness did not differ between the standard-and longrotation plantations. However, the composition of tall-tree species, of different seed-dispersal types, in long-rotation plantations differed from that in standard-rotation plantations, but was similar to that in abandoned coppice forest. These results indicate that, in particular, long-rotation plantations contained more tall-tree species with animal-dispersed seeds, which in turn suggests that long-rotation plantations may be better for colonization of tall-tree species with this type of seed dispersal. The relatively long period since management in long-rotation plantations may play a significant role in the growth, reproduction, and seedfall of naturally regenerated tall-tree species with animal-dispersed seeds. Therefore, long-rotation plantations may maintain and restore species composition via recovering ecological function.forest ecosystem management / seed dispersal / species classification / life form Résumé -Effets de l'allongement de la période de rotation des plantations de Larix kaempferi au centre du Japon sur la diversité en espèces végétales. Nous avons comparé la diversité en espèces végétales du sous bois entre des plantations de Larix kaempferi menées en rotations longues par rapport à des rotations classiques courtes ou des taillis abandonnés. La diversité et la richesse en espèces végétales ne diffèrent pas entre les plantations classiques et les plantations à longue rotation. Cependant, la diversité de la strate arborée, avec des stratégies de dispersion des graines différentes, diffère entre les plantations à longue durée par rapport aux plantations classiques mais est semblable aux taillis abandonnés. Les résultats indiquent en particulier que les plantations avec de longues rotations contiennent plus d'espèces arborées avec une stratégie de dissémination des graines par zoochorie ce qui suggère également que ce type de plantation longue soit favorable aux arbres avec ce type de dissémination. La longue période après la dernière intervention en forêt dans les plantations à longue rotation semble donc jouer un rôle important dans la croissance, la reproduction et la dispersion des graines par zoochorie pour les arbres se régénérant naturellement. Par conséquent, les plantations à longue rotation pourraient maintenir et restaurer la composition en espèces végétales par rétablissement de la fonction écologique. gestion des écosystèmes forestiers / stratégie de dispersion des graines / classification des espèces / type biologique

“…This will be particularly important when extended rotation cutting is employed. It is widely recognized that L. kaempferi plantations generally contain abundant understory vegetation (Nagaike 2002;Nagaike et al 2003), because its thin deciduous canopy allows a certain amount of light to penetrate into the understory (Cannell 1982;Sakaue 1982). The structure and composition of the shrub layer nevertheless differed considerably between the distance classes.…”

Tree retention is understood as a key practice in creating complexity, leading to heterogeneity in resources and habitats in managed stands. In this article, we clarify the long-term effects of tree retention on stand structure and tree-species composition in a 60-year-old Larix kaempferi plantation in central Japan. In our study plot (1.5 ha) there were 18 stems/ha of retained trees (determined by tree-ring analysis), mostly Quercus crispula. We conducted spatial analyses and tested the hypothesis that tree abundance, size structure, and species composition and diversity change with distance from the retained trees. Near the retained trees, L. kaempferi showed a reduction of 40%-60% in basal area, due presumably to the shading effect. In contrast, the nearby area showed greater species diversity in the canopy layer. The retained trees created patches of different species composition in the understory. The spatial gradient of shade and colonization opportunity provided by retained trees greatly affect the distribution of the colonized species, according to their shade tolerance and seeddispersal ability, which resulted in the stand structure with a heterogeneous shrub-layer vegetation. Retention proved particularly important for the enhancement and long-term maintenance of structural and compositional complexity in L. kaempferi plantations.
