TL;DR: The results showed that within the fenced ungulate exclosures, the composition of trees shifted towards fir (Abies alba) and various deciduous trees, whereas outside the fences, spruce became the dominant species and the diversity decreased as an increase in the Diversity of the tree and shrub layer was overcompensated by a significant decrease in the diversity of the undergrowth vegetation.
Abstract: The often highly elevated stocks of ungulates (red and roe deer and chamois) in the Alps shape the composition of the woody vegetation. The aim of this study was to investigate the influence of ungulates on the mixed deciduous and coniferous mountain forest in the district of Reutte, which boasts the highest density of ungulates in Tyrol (Austria), with a special focus on the effect of browsing by ungulates on plant diversity of the herb layer, different shrub layers. and the tree layer. Our results showed that within the fenced ungulate exclosures, (1) the composition of trees shifted towards fir (Abies alba) and various deciduous trees, whereas outside the fences, spruce became the dominant species; (2) the cover of dwarf shrubs and upper and lower shrub layers (1.3–5.0 and 0.5–1.3 m, respectively) increased significantly; (3) the cover of grasses decreased significantly and (4) the diversity decreased as an increase in the diversity of the tree and shrub layer was overcompensated by a significant decrease in the diversity of the undergrowth vegetation. Browsing by ungulates benefited grass species in the understory and altered the relative abundance of tree species in the lower layer which could, over time, result in compositional shifts in the canopy.

TL;DR: In this article, the relationship between ecological indicators and anatomical parameters of teak wood was investigated in the Tchorogo teak plantation in the Central Region of Togo (1°00'E, 8°21'N).
Abstract: In the Tchorogo teak plantation in the Central Region of Togo (1°00'E, 8°21'N), a contribution to the sustainable forest management was implemented through the study of the relationship between ecological indicators and anatomical parameters of teak wood. To do this, three phytocoenoses have been described in the forest, using the synusial approach inside the undergrowth plant communities. In each phytocoenose, silvicultural parameters of plantations and anatomical properties of teak wood were studied taking into account the age of the trees. Results showed that teak productivity level, which is linked to the fibre properties of teak wood varied significantly (F749,2=71.81; P Togolese teak plantations. Keywords: Teak plantation, Togo, phytocoenose, ecological indicators, teak wood, anatomical properties.

TL;DR: A 20-year thinning study in a Wisconsin swamp stand of middle-aged northern white-cedar indicates that advance tree reproduction and shrubs grow little under after a second thinning to less than 150 square feet of basal area per acre.
Abstract: A 20-year thinning study in a Wisconsin swamp stand of middle-aged northern white-cedar indicates that advance tree reproduction and shrubs grow little under after a second thinning to less than 150 square feet of basal area per acre. Balsam fir will probably dominate this undergrowth, particularly if the area is used heavily by snowshoe hare or white-tailed deer.

TL;DR: In this paper, the relationship between the main Cervidae [moose (Alces alces), red deer (Cervus elaphus), and roe deer (Capreolus capreolaus)] species and a complex of environmental factors in an extensive fragmented landscape of Central Lithuania was analyzed.
Abstract: We analyse the relationships between the main Cervidae [moose (Alces alces), red deer (Cervus elaphus) and roe deer (Capreolus capreolus)] species and a complex of environmental factors in an extensive fragmented landscape of Central Lithuania. The highest determining positive influence on moose density was the proportions of wet forest sites. In forest complexes with fewer proportions of wet sites, the most important factor was the total forest area. The proportion of shrub cover, upland and dense undergrowth area, and road density also has significant effect on moose density. The total area of forest complexes has the highest determining positive influence on red deer density. The highest density of red deer was calculated in large forest complexes (>2,745 ha) with a 51 m ha−1 of edges in wet forest (>25.4 %) dominating areas. The proportion of deciduous, coniferous mixed and pine forest, also shrub and density of edges also had significant effect.

TL;DR: In this article, a study was conducted on forest rehabilitation based on indigenous species at the Universiti Putra Malaysia, Bintulu, Sarawak, Malaysia, where the planted seedlings were classified as light demanding, shade tolerant and late growth species on the basis of their height growth performance in the trials.
Abstract: A study was conducted on forest rehabilitation based on indigenous species at the Universiti Putra Malaysia, Bintulu, Sarawak. Areas of open abandoned shifting cultivation, man-made mounds, Macaranga secondary forest and shrubby undergrowth were used for trial planting with different types of planting techniques. The research showed that selected species from the natural vegetation community easily adapt to the site conditions similar to their native habitat. The planted seedlings were classified as light demanding, shade tolerant and late growth species on the basis of their height growth performance in the trials. The indigenous tree species recommended for checkerboard plantations are: Shorea ovata, S. mecistopteryx, S. macrophylla, Dryobalanops aromatica, Parashorea parvifolia, Hopea beccariana, Durio carinatus and Eusideroxylon zwageri.
