  • This study was conducted to evaluate the effects of soil covering and vegetation base materials implementation on the growth of Lespedeza cyrtobotrya Miq. in abandoned coal mine land. We compared the biomass of L. cyrtobotrya at the study plots of four different soil covering depth (control, 10cm, 20cm, and 30cm) and four different compounds of vegetation base materials composed of soil conditioner (S), erosion control (E), and peat moss (P) (control, S+P, E+P, and S+E+P). The result showed that the biomass of L. cyrtobotrya was higher in the study plots implemented with soil covering than control plot, although the increase in biomass was not constant with soil covering depth. In case of the vegetation base materials treatments, the biomass was highest in S+E+P plot, and S+P and E+P plots showed higher biomass than control plot.

  • Background: Bamboo forests provides benefits for nature and the welfare of the people of Turen in Malang Regency and Sumbermujur in Lumajang Regency. They interact with the forest to live through the development of forest potential based on local wisdom. This is believed to prevent various adverse impacts on the forest. Local wisdom is related to beliefs or/and taboos, ethics and rules, techniques and technology, as well as forest/ land management traditions carried out by the community in building, managing forests, and Turen springs in Malang Regency and Sumbermujur in Lumajang Regency. Therefore, it is important to study the potential of bamboo forests in Turen and Sumbermujur for ecotourism, the development of bamboo forest ecotourism in Turen and Sumbermujur based on local wisdom, and the potential of bamboo forests in Turen and Sumbermujur in sustainable spring conservation. Results: Bamboo forest ecotourism has become an attractive tourist attraction. It is also beneficial for environmental conservation and the welfare of the surrounding community. The potential of bamboo forests in ecotourism development consists of various types of old bamboo that are fertile which offer environmentally friendly tourism activities by prioritizing aspects of nature conservation and socio-cultural empowerment of the local community. This cannot be separated from the belief that bamboo has supernatural powers (as a protector), so they do not dare to take or damage the existing bamboo. This behavior has a positive impact on springs that are still sustainable. Conclusions: Therefore, the charm of the bamboo forest is a potential that can be developed through ecotourism based on local wisdom. The development of bamboo forest ecotourism based on local wisdom is able to meet the living needs of the surrounding community.

  • The objective of this study was to provide basic information for selecting the right timing and the right place of erosion control of stream on Gyeongsangnam-do. In order to achieve this objective, a total of 526 erosion control dams and 230 mountains stream conservation facilities on the constructed places and construction planned places for the erosion control were investigated on site, forest physiognomy, and hydrologic conditions. The erosion control dams and mountain stream conservation facilities were mostly constructed in the area, which has the sedimentary rock, 200-400m of altitude, a slope of 21~30°, and II of landslide hazard map. Among the forest environmental factors, it was only similar to the construction frequency in the areas that have small diameter class, III age class. Also, we investigated the hydrological environmental factors that determine the size and numbers of erosion control dam. The places constructed to the highest frequency were below 50ha in the area, 2.1~4.0km/㎢ of drainage density, longitudinal water system, 61~90mm of maximum precipitation per hour, and 201~300mm of day maximum precipitation. As the results, the sites and floodgate conditions between the constructed places and stream conservation facilities for the erosion control showed to be very similar. Therefore, these results indicate that the erosion control of the stream of the areas, which have the disruption of mountain peaks and the high erosion risk areas, should be used on both the erosion control dam and stream conservation facilities.

  • Forests render both a home and a livelihood for people living in and around them. To reconcile the need of local communities with conservation, the Nishorgo Support Project (NSP or Nishorgo) is supporting co-management in five protected areas of Bangladesh, including Rema-Kalenga Wildlife Sanctuary. The main focus of this study is to assess the effectiveness of alternate income generating activities (AIGAs) which is provided by the Nishorgo Support Project. It is a tool for reducing dependence on forest resources by people living in and around Rema-Kalenga Wildlife Sanctuary and also play effective role in forest conservation. This study compares the socioeconomic condition (income, living style etc.) and forest dependency before and after implementation of co-management activities in Rema-Kalenga Wildlife Sanctuary. A total of 11 villages (sampling intensity was 31%) namely Kalibari, Mongoliabari, Chokidarbari, Chonbari, kalenga, Krishnochura, Hatimara, Himalia, Rashidpur, Goramchori and Horinmara were studied. We surveyed 272 households in these villages (Incase of households survey, sampling intensity was 100%). Data analysis shows that the major income generating livelihood activities were agro farming (30%), followed by fuelwood collection (22.50%), nursery raising (12.5%), cattle rearing (10%), fisheries (7.50%) and others. Study also reveals that after being implementation of the co-management activities the average income levels of the studied villages have rises on 578 Tk/households (1US$ = 70 Taka, Taka means Bangladeshi currency). Further more, many of the illegal loggers became forest protector, which make their life more secured. It was also found that peoples of the study villages are now actively engaging in forest management activities and it is the only hope for conservation and restoration of forest resources not only in Rema-Kalenga Wildlife Sanctuary but also in other protected area's of our country.

  • Boeun-gun is hard to develop, because of large numbers of mountains and vast distribution of limited development districts. However it is easy to access from the entire country, and there are large conservation area such as national park and dams. Short-term plans such as attraction of tourists can be established using these advantages. Long-term plans can be planed with stable establishment of continuous considerations and supports. These supports will be rewarded while it demands some time and costs. Private owned mountains can be converted from negligence upkeep of property to utilization of mountains with basic consideration of mountain conservation. This may contribute the essential function of mountain.

  • This study was carried out to introduce current status and development strategy for an environmental restoration of stream side in Japan, and to consider a methodology which could be effectively applied for the environmental restoration of stream side in Korea. The strategy prospects of environmental restoration in Japan were summarized as follows : 1. When we establish the long term erosion control planning, we should make detail planning after considering of a certain block of watershed units. Because most of the disaster is caused by soil movement which was occurred by water contents. 2. Nowadays, the general torrent erosion control planning system in Japan focused on reducing the sediment such as by placement of erosion control facility and by restoration of afforestation, after calculation of several factors including expected amount of sediment, and the different amount of planned sediment and allowable sediment. 3. In the past, the goal of forest conservation and erosion control planing was to fix the amount of soil movement by construction of permanent facilities. While, the goal of forest conservation and erosion control planning in the future needs to change the techniques to a small and middle scale's soil movement which could prevent soil movement from large scale of soil disasters, but allow soil movement effectively. Also, it is considered to change erosion control dams from non passing type to passing type. 4. Restoration of stream-side ecology, erosion control for the conservation of ecology should be planned and conducted cautiously based on concepts of ecology conservation and development of environmentally sound techniques.

  • In Korea, a cooperation charge on conservation of ecosystem is imposed to prevent indiscriminate development. The total amount of this charge is determined by multiplying the size of the destroyed area by a value per unit area and the area index within 5 billion won. Since 2001, the charge per unit area has been determined to be $250won/m^2$. In this study, we estimated the unit value of ecosystem services per year using benefit transfer method, with a focus on forest resources. According to our results, forest resources have a value of about $3,500won/m^2$ per year. When the non-use value is subtracted, that figure becomes approximately $1,300won/m^2$. If this value incorporates the unit value of the cooperation charge on conservation of ecosystem, it will increase. To comply with the original intent of the cooperation charge on conservation of ecosystem, the fund must be used to improve ecosystem services, including the restoration of a destroyed area or the purchase of new land.

  • T Recently, the government has been promoting the expansion and supply of renewable energy as an alternative for achieving carbon neutrality and the nationally determined contributions by 2030. In 2020, the Ministries of Industry and Environment and the Korea Forest Service collaborated to build a nationwide onshore wind energy siting atlas considering wind resources and forestry and environmental regulations focused on central regulations. In this study, the ordinances of the local governments were analyzed to examine the effects of regional location regulations on the expansion of onshore wind power energy generation facilities, in addition to those of central regulations. A development permit standard survey of 226 urban plan ordinances of the local governments nationwide showed that presently in 2022, 52 municipalities are applying regulations on wind energy generation facilities by ordinances. This is twice more than that in 2018, when renewable energy power generation facility development was difficult. Additionally, the location regulations applied by these ordinances were organized by items and regions, and regulatory characteristics, such as the number and scope, were analyzed by regions. To analyze the spatial distribution characteristics, JeollaNamdo was selected as the case area. A spatial DB was established for regulated areas based on the regional and central regulations, and the spatial distribution characteristics and the regulatory scope were compared and analyzed.

  • For policies and actions associated promotion of social and environmental benefits of forest in Korea, various polices have been progressed based on newly established ordinances along with full progresses of subdivision of the Forest Law since reorganization of regulatory system by functions focused on the Basic Forestry Act. In these policies, water resource conserving function and national land conserving function which have little close relation to the people's daily life including formation of forest for conservation of water supply and erosion control have continued to be promoted since 1970s. Especially in recently years, the policy of biodiversity conserving function according to importance of health and recreation function and conservation management of forest ecosystem and animal and plant are being promoted actively. Among them, the health and recreation functions is featured for various policies to be promoted in spite of small budget for responding actively to various forest recreation demands after settlement of 5-day workweek system. It seems because the health and recreation function could obtain visible results of governmental investment and high responses from the peoples as a function having close relationship with the people's daily life.

  • This study was performed to compare the effects of different drainage layers on tree growth at the exposed sites of Saemangeum sea dike. 4 types of drainage layers including control(dredged soil), specially prepared bark, gravel, and wood chip were set in 150~165cm depth of soil. Pinus thunbergii and Celtis sinensis were planted after 9 months of soil treatment. Electrical conductivity(EC) of soil in all treated plots were decreased under $4dS{\cdot}m^{-1}$, and NaCl(%) was decreased under 0.05% after 1 year from soil treatment. Soil moisture at the 120cm depth of the bark treated plot was higher than that of the 180cm soil depth, below the drainage layer. It is considered that vertical mobility of water was inhibited. Organic matter(OM) at the 120cm soil depth increased at bark and wood chip treated plots. Survival rates after 4 years of P. thunbergii and C. sinensis were 100% in all treatments. The height of P. thunbergii was not significantly different among the treatments while the height of C. sinensis was significantly different among the treatments and it was highest at the bark treated plot.
