Forest parks are regarded as one of the scientific ways to keep the forest sustainably developed, meanwhile deliver the benefits to the general public. The development of forest parks in China has experienced simply more than 20 years and both the exploitation and management institutions haven’t been set up systematically, which, in reality, reflects as inadequate legislative and policy framework. Without the regulatory guidance and collaborating assistance of environment relating governmental sectors at both national and local levels, it’s inevitable that the development of forest parks in the country would face constant problems and conflicts. Therefore, it might be helpful to sort out this conflicts and problems and further more to work out how to solve the barriers. The research in this report started with introducing the IUCN Protected Areas Categories, the overall current situations in China and compared the definition of forest parks in the country and that in international experience. It is to aim to find out the real usufruct rights conflicts during the exploitation and management of forest parks and the method used in this report is field visit, previous investigation, collecting secondary materials, interview, analysis and comparison. The research result in this report couldn’t cover all the conflict situations during the forest parks’ exploitation and management in China but will provide the analysis of this problem from the legal perspective. Practical application and concerning suggestion will be fully discussed in Part 5 in terms of legislative, social and environmental effects.

Higher plants provide valuable genetic assay systems for screening and monitoring environmental pollutants. They are now recognized as excellent indicators of mutagenic effects of environmental chemicals and are applicable for the detection of environmental mutagens both indoor and outdoor. 2,4-dichlorophenoxyacetic acid (2,4-D) is a herbicide commonly used in agriculture. The residues of 2,4-D are present in air, water, soil and edible plants. It constitutes a real hazard to the public health because it’s wide spread use in agriculture. Genotoxic effects of 2,4-D on plant cells and potential of higher plants as a biomonitoring system for detecting chemical mutagens are evaluated. It is recommended that higher plant systems have been accepted by regulatory authorities as an alternative biomonitoring system for the detection of possible genetic damage resulting from pollution and the use of environmental chemicals.

Forests potentially contribute to global climate change through their influence on the global carbon (C) cycle. The Kyoto Protocol provides for the involvement of developing countries in an atmospheric greenhouse gas reduction regime under its Clean Development Mechanism (CDM). Carbon credits are gained from reforestation and afforestation activities in developing countries. Bangladesh, a densely populated tropical country in South Asia, has a huge degraded forestland, which can be reforested by CDM projects. To realize the potential of the forestry sector in developing countries like Bangladesh for full-scale emission mitigation, the carbon sequestration potential should be integrated with the carbon trading system under the CDM of the Kyoto Protocol. This paper discusses the prospects of carbon trading in Bangladesh, in relation to the CDM, in the context of global warming.

An exploratory study was conducted in Juri Forest Range-2, a proposed biodiversity conservation area of Bangladeshto explore the present growing stock of tree, regeneration condition and status of non-timber forest products (NTFPs). Thisconservation area contains both natural and artificial plantation was selected by using multistage random sampling method. Fordetermination of plot size and sampling methods, the quadrate size (10 m×10 m) for tree stock measurement, (2 m×2 m) forregeneration survey, (20 m×20 m) for NTFPs survey was determined. Regarding tree stock survey, 14 species under eight familieswere found where Tectona grandis shows average number of stem/ha was 624 and basal area/ha was (10.36 m2/ha) followed byAcacia auriculiformis (0.2 m2/ha and 637 stem/ha), Gmelina arborea (0.2 m2/ha and 600 stem/ha). In regeneration survey, 14species were found belonging to 9 families where Alstonia scholaris shows highest (3,750) seedling per hectare. Regarding NTFPs,bamboo and cane are the most common resources. In last ten years, the total timber output was 1,28,596.14 cubic feet and totalamount of revenue was 4,64,434 US$. The vacant area is 1,335.5 acre which contains 14% of total area. If this vacant area isplanted with suitable species and take proper steps for appropriate management of this species it will be a good biologicallydiversified area.

Dryland species and ecosystems have developed unique strategies to cope with low and sporadic rainfall. They are highly resilient and recover quickly from prevailing disturbances such as fires, herbivore pressure and drought. Dryland people have engineered pastoral and farming systems, which are adapted to these conditions and have sustained the livelihoods of dryland people for centuries. In this article, we present the status of potentials and threats to dryland biodiversity and explore options for its conservation and sustainable use. Findings of the research can be summarized as follows: (i) The ecosystem goods and services are highly valued by the community but mechanism for wise use of the resources has disappeared, (ii) forests are under the ownership of the government but the local community is the realistic custodian of the forests through village leaderships and environmental committees; (iii) the immediate major threat to dryland biodiversity held in the forests appears to be the degradation of ecosystems and habitats caused by new and powerful forces of environmental degradation such as large scale irrigation of rice farms, poverty-induced overexploitation of natural resources, and disappearance and ignorance of traditional institutions for management of dryland biodiversity. These new forms of disturbances often overpower the legendary resilience of dryland ecosystems and constitute potentially serious threats to dryland biodiversity. Forests, wetlands and oases all of which are micro hot spots of dryland biodiversity, appear to be particularly vulnerable hence the need to set up some rules and regulations for sustainable utilization of these resources.

This study was carried out to investigate vegetation structure and soil property of natural habitat of Polygonatum stenophyllum to provide basic information for propagation, conservation and restoration. Habitats of Polygonatum stenophyllum were classified into Hemiptelea davidii-Robinia pseudo-acacia dominant population (Yeongwol-eup), Pinus densiflora-Hemiptelea davidii-Callicarpa japonica dominant population (Nam-myeon), and Hemiptelea davidii-Rubus crataegifolius dominant population (Gangchon-ri). The soil pH 6.49~7.28; and electron conductivity 0.10~0.19 ds/m. The average content of organic matter, total nitrogen, available P2O5, Ca2+, Mg2+, K+, and Na+ were 8.24~16.45 g/kg, 0.02~0.13%, 45.67~123.67 mg/kg, 4.61~6.71 cmol(+)/kg, 0.17~0.63 cmol(+)/kg, 0.06~0.27 cmol(+)/kg and 0.03~0.30 cmol(+)/kg, respectively. Species diversity index (H'), maximum species diversity index (H' max), evenness (J') and dominance (1-J') of investigated sites ranged 1.0323 (Nam-myeon)~1.1134 (Yeongwol -eup), 1.4914 (Gangchon-ri)~1.6128 (Nam-myeon), 0.6401 (Nam-myeon)~0.7270 (Yeongwol-eup) and 0.2730 (Yeongwol-eup)~0.3599 (Nam-myeon) respectively.

Agrobacterium–mediated genetic transformation has been widely used for the production of genetically modified transgenic plants to obtain specific desired traits. Most of the molecular mechanisms that underlie the transformation steps have been well elucidated over the years. However, a few steps, such as nuclear targeting, T-DNA integration, and Agrobacterium-plant proteins involved remain largely obscure and are still under extensive studies. This review describes the major steps involved in the molecular mechanism of Agrobacterium-mediated transformation and provides insight in the recent developments in studies on the Agrobacterium-mediated genetic transformation system. Some factors affecting the transformation efficiency are also briefly discussed.
