Species Diversity of Trees and Forest Floor Plants in Oriental beech Forest Types of Shastkalate Educational and Research Forest, Gorgan)

Trees are the most important biological elements of forest ecosystems. The variability of the tree species composition inhabiting in the Oriental beech forest, not only forms different forest types but also has a remarkable impact on the species diversity of forest floor plants, due to the existence of trees in the overstory layer. In this research, forest types of an an Oriental beech were ide...

Evaluating the Scenic Beauty of Individual Trees: A Case Study Using a Nonlinear Model for a Pinus Tabulaeformis Scenic Forest in Beijing, China

The relationship between scenic beauty grade and measured tree indicators was studied through evaluation of 427 photos of individual Pinus tabulaeformis trees by using the scenic beauty estimation (SBE) method. Thirteen indices to reflect trunk, crown and stem-to-canopy ratios of individual trees were evaluated by invited students. Results showed that students preferred large diameters at breas...
