This study presents an ecological management plan for wildbird habitat conservation, an nature-friendly enhancement of bio-diversity using the riverside of the Tancheon Ecosystem Conservation Area in Seoul by analyzing environmental and ecological characteristics. As a result of analyzing actual vegetation, vegetation type was classified into 34 types. Humulus japonicus association covers an area of 441,568.6㎡(31.44％), and Artemisia princeps var. orientalis association covers an area of 89,690.1㎡(6.39％). Sandy plain as valuable wildbird habitat covers an area of 89,965.9㎡(6.4％). 125 taxa including 34 families, 93 genera, 107 species, and 18 varieties were recorded and the number of naturalized plants were 41 taxa at the survey site. Total naturalized index(NI) and urbanized index(UI) were recorded as 32.8％, and 15.5％. As a result of analyzing the herb plants association structure by surveying 8 belt-transects, the humid native plants was dominant in the partially adjacent revetment edge and damp riverside. On the other hand, naturalized plants was so extensively dominant that it was necessary to establish an ecological management plan. The observed wildbirds belonged to 50 species, 6,118 individuals, and 7 restricted species by law, which were Accipiter gentilis, Falco tinnunculus, Buteo hemilasius, and Buteo buteo. Oriolus chinensis,Hirundo rustica, and Alcedo atthis. The ecological administration plan for Tancheon Ecosystem Conservation Area as follows: in ecological land-use planning, the conservation area(695,518.5㎡) has native woody and herb vegetation and sandy plain with water as an wildbird habitat. The restoration area(653,702.7㎡) has a naturalized plants distribution are with artificial revetment. The nature-friendly Riverside Area(55,414.9㎡) was an easily approached area with damaged riverside vegetation, and a safe area to wildbird habitat. In riverside restoration planning, the artificial riverside should be restored to its natural riverside vegetation, and the artificial embankment should be restored with edge shrubs for wildbird habitat or revegetated for natural riverside landscape. For naturalized plants management planning, we selected naturalized plant species to be weeded out, and suggested an application method for ecological management.

The present studwas undertaken to classify and describe the riverside vegetation around Hanchon (36°27’-36°51’N, 128°15’-128°37’E), a tributary in the upper stream area of Nak-tong River, South Korea by methods of the ZM school of phytosociology. As a result the vegetation was divided into twenty three associations and communities belonging to ten classes. Reflecting various human impacts in the past, the associations and communities of the Artemisietea principis were most plentiful there. The vegetation units obtained in the present study were as follows: A. forest vegetation A-1 Fagetea crenatae:Zelkova serrata community, Larix leptolepis community; B. Shrub vegetation B-1 Salicetea sachalinensis:Salicetum gracilistylae, Salicetum graciliglandis assoc. nov., B-2 Rosetea sachalinensis:Salicetum gracilistylae, Salicetum graciliglandis assoc. nov., B-2 Rosetea multiflorae:Stephanandra incisa community, Lycium chinense community; C. Grassland vegetation C-1 Lemnetea minoris:Spirodela polyrhiza-Lemna paucicostata community, C-2 Bidentetea tripartiti:Polygonetum thunbergii, Polygonetum sieboldii-hydropiperis, Panico Polygonetum hydropiperis, Pharagmitetea :Oenantho- Phalaridetum arundinaceae, Phragmitetum japonicae, Miscanthetum sacchariflori, Phragmites australis community, C-4 Artemisietea principis:Artemisia princeps community, Impatiens textori community, Lactuco indicae-Humuletum japonicae, Pueraria lobata-Humulus japonicus community, Pennisetum alopecuroides community, C-5 chenopodietea:Echinochloa crus-galli var. orizicola community, Digitaria adsecendens community, Polygonum nodosum community, C-6 Miscanthetea sinensis: Miscanthus sinensis community, C-7 Plantaginetea:Eragrotis multicaulis-Plantago asiatica community. It is inferred that the endemic vegetation units in the riverside vegetation of Korea are very rare, because most of the vegetation units obtained in the present study are common with those of Japan. Among the above vegetation units, the Salicetum graciliglandis was established as a new association. On the other hand, the associations and communities of classes characterizing the riverside vegetation increased with a decrease of human impacts from the downstream to the upstream in Hanchon, while the number of the naturalized plants was the reverse. Also based on the present phytosociological work, the relation between the vegetation units and their environmental conditions and the restoration ecology and nature conservation of the riverside vegetation were discussed here in detail.

This study conducted observations at 72 traffic lights and road signs in Sejong-si, Korea from March to June 2019 in order to analyze nest-site, nest-site characteristics and feeding behavior in Tree sparrow (Passeer montanus) in urban. Feeding behavior during breeding season in 2019 was investigated at 10 Town representing traffic facilities installed on the road located in the center of the city and 10 Riverside Geumgang river's riverside road. We fitted both general linear model and regression model to our field data and estimated the spatial variation of initial date of the first feeding (i.e., being date of breeding) and the total number of caterpillar fed by parents per hour. Our results showed that the frequency of nest building on artificial structures, such as traffic lights, was about 26% higher and about 8 days earlier in the riverside. In particular, the first feeding was significantly faster when the nearest distance between nest to green field as foraging site was shorter whereas there was no significant effect of the number of nest within 50 meters on the first feeding. Number of caterpillars fed by parents was higher in the Riverside than in the Urban, and especially the number in the second brood was sharply decreased in the Urban. As we estimated average amount of caterpillars per hour to 446 traffic safety facilities in Sejong-si, it was estimated that Tree sparrows fed 18,742.8 caterpillars per hour during the breeding season. In this study, we showed that characteristics of nests built in artificial structures and feeding behavior in order to analyze effects of environmental condition in urban on life-history traits during the breeding season. Finally, we discussed the conservation of birds in urban and pest control effects.

본 연구는 2000년 일부 구간이 자연형 하천으로 복원된 불광천을 대상으로 하여 한 하천 내에 정비방식이 다른 직강화 하천구간과 자연형 하천복원구간으로 구분하여 식물상 및 식물종의 출현빈도를 비교 분석하였다. 조사는 2003년 5월과 8-9월에 걸쳐 이루어졌으며, 식물상은 하천의 양안에 출현한 모든 식물을 동정하여 정리하였고. 식생은 200m를 기준으로 하여 Belt-transect 방법을 이용하였다. 2003년 5월 및 8-9월은 직강화 하천구간에서는 33과 73속 88종의 식물이 출현하였고. 자연형 하천복원구간은 36과 76속 90종의 식물이 출현하였다. 귀화율 (Naturalized Index：Nl)은 직강화 하천구간은 22.7%, 자연형 하천복원구간은 21.1%였고, 도시화지수 (Urbanization Index：Ul)는 직강화 하천구간이 7.8%. 자연형 하천복원구간이 74%로 직강화 하천구간이 자연형 하천복원구간보다 약간 높았다. Belt-transect 조사법에 의한 식물종 출현빈도 결과는 직강화 하천구간에서는 하안에는 여뀌와 환삼덩굴이 제방에는 망초와 큰비짜루국화가 가장 높은 출현빈도를 보였다. 이에 반해 자연형 하천복원구간에서는 하안에는 갯버들, 여뀌, 소리쟁이. 환삼덩굴이, 제방에는 망초와 큰비짜루국화가 가장 높은 출현빈도를 보였다. 즉 직강화 하천구간과 자연형 하천복원 구간은 제방에는 구간에 따른 차이가 없고, 하안의 경우에는 자연형 하천복원구간에 도입된 갯버들이 출현하여 차별을 보였다.

This study was conducted to present the ecological management of Goduk Riverside Restoration Area in Hangang, Seoul by analyzing the change of the vegetation structure. The survey site was classified into three groups. These were the vegetation restoration area, the dry plant area, and the swampy plant area. There were 141 taxa including naturalized plants and 13 species recorded in 2001 and 258 taxa including naturalized plants and 42 species were recorded in 2003 by monitoring. Monitoring results showed that the alien plants such as Humulus japonicus expanded continuously except in the vegetation restoration area. It was found that the growing status of planted shrub plants were poor, and the naturalized plants status was thriving, and the soil environment was bad in the vegetation restoration area. The alien plants such as Humulus japonicus and Aster pilosus dominated continuously in the dry plant area. The swampy native herb plants number was decreased, but the Humulus japonicus community was expanded caused by the soil drying in the swampy plant area. Soil analysis showed that the soil acidity, the available phosphates and the concentration of calcium were highly effected by cultivation. We propose ecological management as follows based on the results of the change of vegetation and soil characteristics. The vegetation restoration area should be managed by visitor's characteristics. Replanting vegetations should be based on soil characteristics. The removal of naturalized plants and established monitoring with plots is also needed. In the dry plant area and the swampy plant area, naturalized plants need to be removed in order to facilitate bio-diversity and monitoring.
