Deforestation such as illegal logging and forest fires has caused a big disadvantage for surrounding people. In general, the losses were disasters such as floods, landslides and droughts. Disaster is something that causes damage, loss or misery (The Big Dictionary of Indonesian Language, 1996). Gendol hill is a forest area that has experienced disasters caused by forest destruction. Among the disasters occurred in Gendol hill area was drought or difficulty in fulfilment of the need of fresh water. A number of springs have been drying up after the destruction of Gendol forest in 1963. Efforts to restore the forest by reforestation or replanting have been conducted since a long time by the government (Perhutani) with planting of pine trees (Pinus merkusii). Since 1996, trees of Moraceae family were also planted gradually by local person. Three species from the Moraceae family that have been planted are Ficus benyamina, Ficus annulata, Ficus retusa, Ficus recemosa, Ficus microcara etc. By 2016, at least 4000 trees species from Moraceae family have been planted together thousands other species. Based steps of planting, there are three groups of Moraceae family trees in Gendol hill. They are tree groups aged 15-20 years, 10-15 years and 1-10 years (Anonimous, 2016) The case study aimed to get information of Moraceae family trees plantation benefits in emergence of springs. Observation, in-depth interview, documentation and study literature were conducted for this study in April 2016. Observation of the field conditions (vegetation and springs conditions) was conducted to obtain description of the location and springs condition. In depth Interview has conducted by interviewing of key persons to obtain historical information (forest destruction, loss of springs, replanting efforts, and re-emergence of springs). In-depth interview also aimed to get information about the benefits received by local people from the emergence of springs. While documentation in the form of photos of vegetation conditions and springs was taken to get more descriptions. To complete this research, we has also taken secondary data from related parties and some literatures. Furthermore, the collected data analyzed by descriptive-qualitative analysis method. The results showed that the planting of Moraceae family trees such as Ficus benyamina, Ficus annulata Blume, and Ficus retusa L. had a real benefit in emergence of springs on study site including re-emergence of died springs. There are many springs appearing in both large and small sizes. Five springs in quite large size appearing around the Moraceae family trees stand on the slopes of Gendol hill after 17 years of planting. The water yield of each springs was directly proportional to the amount and size of Moraceae family trees around the springs. The water discharge (outflow) of springs under 5 trees with height average 14 m and diameter 25 cm is bigger than the springs under 3 trees with height average 12 m and diameter 20 cm. The emergence of springs in Gendol hills has brought many benefits to the lives of the surrounding people. Based on descriptive analysis, the benefits for local community are; 1) Fulfilment of fresh water needs for at least 800 families of local communities (at least 240,000 litters / day), 2) Increasing of water availability for irrigating rice fields (from 1 harvest / year to become 3 harvest / year) so that people income around Gendol hill increased, 3) Increasing of public awareness in planting / greening including local government, 4) Appearing of tourism service potential that may be developed by local government together local people . Therefore, advanced research or applied research is suggested to be conducted for assessing the effect of Moraceae family trees on all aspects (vegetation, soil, hydrology and socio-economic). The research suggested are; a) The characteristics of vegetation on the springs area and their relation with springs, b) The effect of Moraceae family trees on water yield, c)Affecting factors in the springs sustainability (physical, socio-economic and institutional, d) Environmental services analysis of Springs management.

Distribution of tree species around springs and trees-springs interplay possibility in the springs area of Soloraya, Central Java, Indonesia

The research aimed to analyze the distribution of trees species around springs in various environmental factors and the trees-springs interplay possibility in Soloraya region, Indonesia. Investigation was conducted by survey using census method within 10m radius toward upstream from the point of vegetated springs or previously overgrown by trees. Cluster analysis and discriminant analysis divided 59 springs areas into four (4) groups based on environmental characteristics summarized into two (2) general groups (lowlands and highlands). Only Ficus benjamina was widely distributed shown by high value of relative frequency in entire areas (80%) and high value of indicator species in both lowlands and highlands which was statistically similar. Particular species were obviously dependent on environmental factors (Samanea saman and Innocarpus fagiferus for lowlands, Artocarpus elasticus and Bischofia javanica for highlands). Species dependency on environmental factors was also performed by Canonical Correspondence Analysis showing 0.604, 0.538 and 0.647 of correlation coefficients for elevation, average rainfall and average temperature, respectively. This research also found an association between trees condition and water-flow of springs. It was supported by 0.57 of contingency coefficient which was statistically significant. The information obtained was expected to lead restoration/rehabilitation efforts on the spring protection zone. Adding the number of samples and environmental factors were suggested for future research to get more information. Deeper investigation on the role of the trees around springs was also suggested.

본 연구는 계룡산국립공원 공원문화유산지구로 지정된 동학사, 갑사, 신원사를 대상으로 식물사회학적 식생조사자료를바탕으로 식생구조를 파악하여 생태적 특성을 구명하여 사찰림의 생태적 보전관리 방안을 마련하는데 기초 자료를 제공하고자2018년 9월부터 2019년 5월까지 총 29개소의 산림식생조사를 수행하였다. 계층적 군집분석 결과, 느티나무-으름덩굴-황매화군락(VU1), 졸참나무-작살나무-까치박달군락(VU2), 소나무-산벚나무-쇠물푸레나무군락(VU3)으로 식생유형이 각각 구분되었으며, 각 식생단위별 지표종은 각각 12분류군, 8분류군, 6분류군으로 나타났다. 중요치 분석 결과, 모든 식생단위에서느티나무의 중요치가 가장 높게 나타났으며, 종다양도 분석 결과, 식생단위 3의 종다양도가 0.939으로 다른 식생단위와비교하였을 때 상대적으로 높게 나타났다. 식생유형과 무생물적입지환경, 생물적입지환경과의 상관관계분석을 CCA를 통해분석한 결과, 무생물적 환경인자와의 관계는 식생단위 2와 해발고도가 음의 상관관계를 가지는 경향을 보였으며, 생물적환경인자와의 관계에서는 뚜렷한 상관관계가 나타나지 않았다. This study was carried out to provide basic information for the ecological preservation management of temple forest (Donghaksa, Gapsa, Sinwonsa) by investigating the ecological characteristics of vegetation structure of the Cultural Heritage Site in Mt. Gyeryongsan National Park based on the Braun-Blanquet vegetation survey method from September 2018 to May 2019. As a result of hierarchical cluster analysis, the forest vegetation was classified into 3 vegetation units (Zelkova serrata - Akebia quinata - Kerria japonica community, VU1; Quercus serrata - Callicarpa japonica - Carpinus cordata community, VU2; and Pinus densiflora - Prunus sargentii - Fraxinus sieboldiana community, VU3). The indicator species of each vegetation unit were 12 taxa, 8 taxa, and 6 taxa, respectively. The result of the importance value analysis showed that Z. serrata had the highest importance value in all vegetation units, and the result of the species diversity analysis showed that the species diversity of VU3 was 0.939, which was relatively higher than other vegetation units. The result of the CCA of correlation between vegetation units and abiotic environmental factors showed that VU2 had a negative correlation with altitude, and biotic environmental factors had no significant correlation with vegetation units.
