This mini paper reviewed key principles of carbon sequestration in the concept and quest to understand that land and forests have been accounted huge potential source of storing and referred as natural scrubbers or natures "carbon sinks". Generally, in scientific term, one way of reducing the emissions of carbon dioxide into the atmosphere is to store carbon or CO2 in any medium other than the atmosphere. This paper outlines the main definition and estimates of amount of CO sequestered annually by plants while determining the total (green) weight of the tree, determine the weight of carbon in the tree and the weight of carbon dioxide sequestered in the tree. Prominent evaluation examples involve maple-beech-birch forests and white and red pine forests (25 and 120 years) while reflecting to world agro forestry sequestration calculation. Furthermore, the paper discusses the key process of trees as collectors of CO2: chemistry of the action. The mini review concludes the assertion and supported by UN Framework Convention on Climate Change (UNFCC) and the global order of Clean Development Mechanisms (CDM).

The knowledge and experiences in forest management requires the need for response to global change ecology and its interacting factors. This paper reviews the main perceived challenges that climate change poses to forests and global environment. At a global level and it is relevant to understand changing natural ecosystems whereby to all types of forests that include boreal, temperate, and tropical, to various management objectives (production, conservation, protection and multi-purpose) and to all types of management platform (public, private and community) are effected by environmental developments. This review paper addresses (1) Sustainable forestry concepts, (2) Environmental developments and (3) interacting factors of global change ecology and initiatives supported by international community with special interest in REDD+ and Carbon Initiatives. Generally, the functions of global institutions such as FAO enhances the development of models for forest dynamics, integration and analysis with reference to potential for solving climate change challenges in a global change ecology perspective.

There is need to explore the relationships and assess plant community census and patterns. In 18 grid plots in Dalingshan forest was used to conduct plant community structure and abundance evaluation. Plant and vegetation community types were analyzed using TWINSPAN-PC ORD (Two-way Indicator Species Analysis). A field survey was conducted and GPS based map was established. Field/grid map and TWINSPAN were employed to identify species abundance within spatial nutrient distributions. The study was designed to grid the site at 200 x 200 m spatial patterns. 18 grid plots were adopted to identify species abundance and characteristics and total of 99 species observed. TWINSPAN using the PC-ORD software was applied to develop four groups plot dendogram. The entire field procedure was used to establish species census and abundance spreadsheet which aided census of species at medium abundance identified Rhuschinensis (Rch) of abundance (95), Adiantumcapillus (Aca) abundance (90), Blechnumorientale (Bar) abundance (87) and Agaratumconyzoides (Aco) abundance (80). Species of optimum abundance identified Hedyotisauricularia (Hau) 3767, Miscanthussinensis (Msi) 2520, Lophatherumgracile (Log) 833 and Mikaniamicrantha (Mmi) 803 respectively. In furtherance, the results showed that species of floristic composition identified at optimum abundance in percentage (%) include Hedayotisauricularia (32%), Mikaniamicrantha (21%), Hophatherumgracile (7%) and Mikaniamicrantha (7%). This study thereby suggests that the species evaluation can be utilized for further studies on multifactor ecosystem responses towards regional ecological restoration. However, it is critically required to conduct further studies on spatial patterns of soil nutrient distributions in both forest regimes and at regional level.
