Fourteen dictyostelids(12 species of genus Dictyostelium. 2 species of genus Polysphonylium) oc-curred in Mt. Chiri Korea. Soils samples were collected from the nine sites. In the broadleaved-deciduous forests and conifers, common species of cellular slime molds are Dictyostelium mucoroides, and D. brefeldianum. Only two species are above 30 in importance value and above 50% in presence. Dominant species in the broadleaved-deciduous forests is D. mecoroides wheras in the conifer forests is D. brefeldianum which was not common until now in Korea, found in the low elevation either. In addition, Five cellular slime molds occured in the Miscanthus sinensis community: 4 species of genus Dictyostelium and 1 species of genus Polysphonylium. Dominant species is D. purpureum. Importance value is very high, 85. This Result is exceptively unusual. It dind't occur in the other sites. Correlation between the altitudes and the occurrence and distribution of dictyostelids was not accurate. Merely dominant species were different according to forest types and organic matter contents in soil. Cellular slime molds have different favorite forest types. And the growth and germination are dependent on the soil enviroryrnental conditions and soil quility. Key words:Dictyostelids, Mt. Chiri D. mecoroides, D. brefeldianum. D. purpureum. Soil quility, Favorite forest type, Soil environmental condition.

본 연구는 산림치유 프로그램 개발을 위한 일반 성인의 숲과 숲길의 선호도에 관한 연구이다. 숲과 숲길의 선호도에 대한 수요자 선호를 파악하여 보다 표적화되고 차별화된 산림치유 프로그램의 개발을 위한 기초자료 제공을 목적으로 실시하였다. 이를 위해, 잠재 수요자인 일반 성인 남 여를 대상으로 2014년 4월 19일부터 6월 30일까지 온라인 설문으로 숲과 숲길의 선호에 관한 설문조사를 실시하였다. 본 연구에서는 총 613부의 유효표본이 실제 분석에 사용되었다. 자료분석은 SPSS 21.0 프로그램을 사용하여 기술통계분석, 빈도분석, 교차분석, 다중응답분석을 통해 인구통계학적 특성(성별, 연령, 교육수준, 직업, 월평균 가계 소득)에 따른 숲과 숲길의 선호도의 차이를 살펴보았다. 분석 결과, 선호하는 계절의 숲은 봄, 가을, 계절 상관없음, 여름, 겨울 순으로 나타났고, 성별, 연령, 월평균 가계 소득에 따라 선호도에 유의한 차이가 있는 것으로 조사되었다. 선호하는 상태의 숲은 월평균 가계 소득에 따라 선호도에 유의한 차이가 있는 것으로 조사되었다. 산림치유 프로그램 장소로서 선호하는 숲은 자연휴양림, 치유의 숲, 도시숲, 공원, 학교숲 순으로 응답하였다. 거주지로부터 프로그램 장소까지의 거리에 따른 선호하는 숲을 조사한 결과 모든 경우에 대해 통계적으로 유의한 차이가 없게 나타났다. 숲길의 형태에 관해서는 약간의 경사가 있는 길을 가장 선호하는 것으로 조사되었다. 산림치유 목적으로 1회 걸을 때 선호하는 숲길의 길이는 1.5~3km, 1.5km이하, 3km 이상 순으로 나타났고, 성별과 연령, 교육, 월평균 가계 소득, 교육에 따라 선호도에 유의한 차이가 있는 것으로 조사되었다. 이러한 산림치유 프로그램 개발을 위한 일반성인의 숲과 숲길조사를 통하여, 성별, 연령, 교육수준, 직업, 월평균 가계 소득에 따라 숲과 숲길에서의 프로그램에 차별성을 두어야 할 것으로 판단된다. 특히, 연령에 따라 차별화된 프로그램이 제공되어야 할 것으로 판단된다. 본 연구 분석 결과가 성인을 대상으로 하는 산림치유 프로그램 개발을 위한 기초자료로 활용되기를 기대한다.

The Hajong are the ancient tribal forest community among the ethnic minorities of the North-East region of Bangladesh. The study was carried out with respect to three income groups highlighting their indigenous knowledge. A total of forty-five households (fifteen from each income groups) were assessed using different participatory appraisals through semi-structured questionnaires. A special type of indigenous knowledge on food habit was explored in the Hajong community, which correspond to the severe dependence on forest resources. They collect their food resources from homestead forest (45%) followed by forest (40%), market and others. They have indigenous hunting procedure to trap the animal in the forest. Twenty three tree species were tremendously planted in their homestead forests which are the very important source of food. Male are highly responsible to collect the food materials from forest as well as other sources.

This study was conducted to evaluate the effect of forest fire on natural distribution and regeneration of Pinus densiflora Sieb. & Zucc. in Goseong, Gangwon province, Korea. After 13 years of the last forest fire in 2000, five investigation plots ($10m{\times}10m$) in each of rocky land and ridge, the well-known location as a favorite site for natural distribution of P. densiflora, were set to investigate stand characteristic and soil environment including physico-chemical properties and moisture contents of soil. Also, five investigation plots in slope area were set and investigated as well. The concentration of organic matter, total nitrogen, and exchangeable nutrients ($K^+$, $Ca^{2+}$, $Mg^{2+}$) were highest in the slope while the soil in the rocky land showed the lowest concentration of organic matter, total nitrogen, available $P_2O_5$, and exchangeable nutrients ($K^+$, $Na^+$, $Ca^{2+}$, $Mg^{2+}$). The soil in the slope only showed higher concentration of total nitrogen, $K^+$ and $Ca^{2+}$ than the unburned area in Goseong. Mean soil moisture contents in the rocky land (5.77%) were lowest while the slope (15.78%) and the ridge (15.27%) showed almost three times as much than the rocky land. P. densiflora was dominant in the rocky land and Quercus spp. were dominant in the ridge and slope. The average proportion of P. densiflora was highest in rocky land (58.4%, 14.6 trees per plot) followed by the ridge (25.2%, 7.8 trees per plot) and the slope (11.3%, 3.4 trees per plot) while the average height of P. densiflora was highest in slope (277cm) followed by the ridge and the rocky land. The height and crown width of Quercus spp. were higher than P. densiflora in the every plot. The results suggest that P. densiflora may be able to naturally regenerate and survive in the rocky land after the fire while P. densiflora in the ridge and the slope are suppressed by Quercus spp.

It is important to consider urban parks and greenery not only from the viewpoint of amenity or aesthetics but also from the viewpoint of biodiversity. In this study, we focused on bryophytes (mosses), and analyzed how existence of artificial structures in urban greeney, such as concrete curbs and stone walls, affect species diversity of bryophytes. Kyoto Gyoen in Kyoto City, western Japan, was selected as the study site. In consideration of kinds of substrates on which bryophytes grow, microhabitats of Kyoto Gyoen were divided into ten types including concrete curbs and stone walls. In each type of microhabitats, we selected the area where bryophyte diversity was highest, and established a quadrat for bryophyte flora survey. Our results showed that the number of bryophyte species and growth forms and the value of diversity indices on concrete curbs or stone walls were higher than the averages of those. The bryophyte species were divided into the four groups by TWINSPAN as follows: Group A (epiphyte species), Group B (rocky species), Group C (roadsides, grassland or forest species), and Group D (waterside species). Bryophytes classified into Group B (rocky species) were mainly recorded on concrete curbs or stone walls. It was considered that the existence of artificial structures (concrete curbs and stone walls) provided favorite habitats for the bryophytes classified into Group B (rocky species), which mainly grows on concrete or rocks, and enhanced species diversity of bryophytes in Kyoto Gyoen.
