Structural characteristics of forest state

The difference in the quality of the trees between the four states was really significant, as the Sig value of the Chi-square test is 0.000 (less than 0.05). Stages IIA and IIB had mainly species of pioneer species, while IIIA1 and IIIA3 had more shade tolerant species. Stage IIIA3 had the highest level of species diversity.

Results from this study showed several characteristics of structure, composition and tree species diversity of the medium and rich forests in the tropical moist evergreen forests of the Truong Son Forestry Company, Quang Binh province. A total of 4 plots of 100m × 100m each placed in two forest states were surveyed and all stems ≥ 6 cm DBH were measured. 3661 live stems ≥ 6 cm DBH were encountered, representing 40 families and 70 tree species.

This study was conducted to understand altitudinal changes in stand structure and tree species diversity in evergreen broadleaf forest in core zone in Xuan Nha Nature Reserve. Six plots (20 m x 40 m), distributing between < 1,000 and > 1,000 m above sea level were used for stem census. All stems with diameter at breast height (DBH) ≥ 6 cm were identified to species and measured for DBH and height.

To better understand the international perspective of public policies for the elderly, in line with the parameters that serve as tendencies for national policies, one must contextualize international health conferences that had health promotion as their central topic.

Health promotion is seen as a process of community qualification, aiming to improve life and health conditions.
