“…The seed trees are eventually logged after there has been sufficient regeneration, although few those have actually been harvested in most of the stands managed by this system to date. Shelterwood logging has been reported to make effective beech regeneration more difficult in many Japanese beech forests, but this method might not significantly affect plant species diversity (Nagaike et al 1999).…”

Beech (Fagus orientalis Lipsky) is the most industrial commercial tree species among more than 80 broadleaved trees and shrubs in Hyrcanian forests. In this study some of the silvicultural properties of beech were studied under a shelterwood cutting system in a regeneration unit of 25 years old stand in Sangdeh forests of Iran. Tree height, diameter, canopy cover, variety of species, frequency at different stages of growth (seedling, sapling, thicket and pole) and tree density at juvenile phase were recorded in 431 circular 1,000 m 2 sample plots before and after shelterwood cutting. Results indicated that tree density in the diameter at breast height (dbh) class of < 20 cm increased during shelterwood cutting. Canopy cover of regeneration unit was 78.5% in 1957, while in 2000 and after the shelterwood cutting it reached 59%. Growing stages of regeneration were 14% sapling, 21% thicket, 24% small pole and 41% pole. The shelterwood method has not been very successful in our study area due to a number of technical and potential problems.

“…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

“…Therefore, the shelterwood silvicultural system did not affect tree richness. Nagaike et al (1999) also reported this result in Japan's beech (Fagus crenata) forests. In addition, Deal (2001) found no significant differences in species richness between the uncut and partially cut plots in the forest plant communities of western hemlock -Sitka spruce stands in southeast Alaska.…”

“…Previous research indicated that the response to forest management or changing forest structure after logging varied from species to species. It was stated that common species were less susceptible to the effects of harvesting operations than rare species (Nagaike et al 1999).…”

ABSTrACT:To clarify the effect of shelterwood silvicultural method on the diversity of plant species in a beech (Fagus orientalis) forest in the north of Iran, we compared the plant species diversity in three compartments (treatments) where regeneration cuttings were performed with that in a primary compartment. The sampling procedure was a systematic random method and the tree, tree regeneration, shrub and herbaceous species were identified and measured within sampling plots. Results indicated that the mean tree richness in compartment No. 1 (only with one seed cutting) was higher than in the other compartments. The mean richness of understorey species in compartment No. 4 (with all regeneration cuttings) was higher than in the other compartments. The mean evenness (E Var ) of tree species in compartment No. 4 was higher than in the other compartments. The mean evenness of understorey species in compartment No. 1 was higher than in the other compartments. The mean tree diversities (i.e. 1-D, N 2, H´ and N 1 ) in compartment No. 1 were higher than in the other compartments. In addition, the mean diversities of understorey species in compartment No. 1 were higher than in the other compartments.
