Bird communities on the II woodlots in a rural area near large cities were surveyed in wintering season from January to March 1995 to analyze the factors influencing the distribution of bird. Based on the species composition of bird, the woodlots were classified into three groups by TWINSPAN. The result showed that woodlot area is an important factor of the species composition. The ratios of edge with agricultural fields were significantly different between two woodlot groups. It was indicated that agricultural fields in the neighborhood influenced the species compositions of bird within woodlots. The necessary of buffer zones between agricultural field and woodlots against the invasion of agricultural bird species.

We studied relationships between compotion of bird community and vegetation types in woods on the Musashino Uplands and Sayama Hills. One hundred study sites were located on nine woods of which the biggest one was 1340 ha and the smallest one was 15 ha. Bird communities were censused by point counts method at each site on breeding season in 1994. In each site 20m×20m quadrat was established for vegetation survey. In each quadrat all plant species observed were recorded with their coverage. Our results showed that species composition of bird communities changed with that of vegetation. Based on the species composition of bird, the 100 sites were classified into four site groups namely, Group A to D. Based on the species composition of plant, vegetation of the 100 sites were also classified into four vegetation types namely, Type 1 to 4. Most sites of bird Groups A and D were corresponded with ones of vegetation Types 1 and 4, respectively. Short tailed Bush Warbler Cettia squameiceps and Japanese White-eye Zosterops japonicus were characteristically recorded in vegetation Type 1. At the sites of vegetation Type 1 Qurcus cerrata and Styrax japonica were dominant in the tree layer and there were dense shrub layers composed with some evergreen species. Some bird species which are prefer to grassland or thin forest habitat were characteristically recorded in vegetation Type 4 which is lack of shrub layers.

Bird communities on the 20 fragmented woodlots in a suburban area were surveyed in the Tokorozawa City, Central Japan, to analyze the factors that influenced the distribution of birds. Our results showed that woodlot area is an important predictor of the number of individuals and the species richness of birds in each woodlot. Based on the species composition of birds in wintering season, the fragmented woodlots were classified into four types by TWINSPAN: those are core woodlots, woodlots surrounding core ones, isolated and small woodlots, and isolated and middle-sized woodlots. By canonical discriminant analysis, it was indicated that the connectivity between woodlots and the vegetation structure are also important factors influencing bird communities. The necessity of controlling these factors for avian conservation was pointed out.

Species composition and vegetation structure of Quercus serrata woodlots were surveyed in the western part of Tokorozawa City, Saitama Prefecture, Japan, by line transect method. Forty transects were placed in 17 woodlots. Possible ways of succession of Q. serrata woodlots were discussed. No apparent differences in species composition were observed in the overstory of the studied woodlots; Q. serrata and Stylax japonica were dominant in the upper tree layer and in the lower tree layer, respectively. In the shrub layer, a large number of individuals of Q. myrsinaefolia, which is considered to be a dominant species of the potential natural vegetation of the studied area, was observed. Chamaecyparis obtusa, that is an evergreen coniferous tree species and is said to have been introduced artificially into the studied woodlots, was also recorded abundantly in the shrub layer. It appears that both Q. myrsinaefolia and C. obtusa can be dominant in future.

都市近郊に残存する樹林地において,ダミーの卵を入れた人工巣を設置して卵が捕食される状況を調査し,樹林地における捕食圧の空間的なパターンを明らかにすることを試みた.調査は,東京都と埼玉県の境に位置する狭山丘陵の比較的大規模な樹林地とその周辺の孤立樹林地5ヵ所の計6ヵ所で行った.樹林地では,周囲から侵入してくる捕食者によって,林縁付近においては被捕食率が高くなることが予測されたが,林縁からの距離と被捕食率の間には統計的に有意な相関は認められなかった.また,面積の小さな樹林地では被捕食率が高いことが予測されたが,比較的大規模な樹林地でもっとも被捕食率が高く,その他の孤立樹林地と有意な差を示した.最も面積の小さい樹林地で捕食率は最低であった.生息密度の高さからハシブトガラスが主な巣の捕食者であると考えられるが,ハシブトガラスの密度は狭山丘陵の樹林地で最も高く,またハシブトガラスは樹林地周辺に限らず樹林地内部でも多数観察された.このことから,鳥類の巣における捕食は,主な捕食者の樹林地内外の分布状況によって大きな影響を受けていることが示唆される.

We studied relationships between bird communities and vegetation structure on isolated woodlots in Tokorozawa City, Saitama Prefecture, Central Japan. Twenty-four sites were located on two isolated woodlots of which ones were 14.5 ha and 7.8 ha, respectively. On wintering season in 1994 bird communities were censused for 20 minutes by point counts method in each site. In each site two 40m long transects and one 50×2m quadrat were established for vegetation survey. Vegetation structure and composition were recorded at 40 points (spaced at 2m intervals) along these lines and basal area of woody plant species (>1.5m) was recorded in the quadrat. Our results showed that vegetation cover density was found to correlate with the bird species richness on wintering season. Based on the species composition of bird, 24 sites were classified into four types namely, type A to D. On type B and D Bush Warbler Cettia diphone and Black-faced Bunting Emberiza spodocephala were characteristically recorded. Vegetation cover density in shrub and herb layers on type B and D sites was significantly higher than that on type A and C sites. Type A had poorest species richness in all types. Vegetation cover density on type A sites was significantly lower than that on type C sites. On type B sites Japanese Green Woodpecker Picas awokera was characteristically recorded. The total basal area of dead trees on type B sites was larger than that on type D sites, however the difference was not significant.

From November 1995 to early April 1996, 376 individuals were banded in an extensive forest and two isolated woodlots in the Sayama Hills, Central Japan. Each captured individual was fitted with a numbered metal ring and celluloid colored ring. A large number of individuals (15 or more) were banded for Japanese Pygmy Woodpecker Dendrocopos kizuki, Brown-eared Bulbul Hypsipetes amaurotis, Red-flanked Bluetail Tarsiger cyanurus, Pale Thrush Turdus pallidus, Japanese Bush Warbler Cettia diphone, Varied Tit Parus varius, Great Tit Parus major, Japanese White-eye Zosterops japonicus and Black-faced Bunting Emberiza spodocephala. Pale Thrush, Varied Tit and Japanese White-eye were captured more frequently in the extensive forest than in the isolated woodlots, while Great Tit and Black-faced Bunting were captured more frequently in the woodlots. The number of the captured individuals took the maximum in January, perhaps because fruits of Eurya japonica, a typical shrub species favored by most birds in the study area, were a vailable during this month. Several movements of Varied Tit and Long-tailed Tit Aegithalos caudatus within the study area were observed. A Long-tailed Tit moved from one of the isolated woodlots to the other (a distance of about 100 m). Sixty of the 376 banded individuals were recaptured at the same banding site. Recapture ratios of Japanese Bush Warbler, Pale Thrush and Red-flanked Bluetail, which frequent the shrub layer, were very high. On the other hand, although a large number of Great Tit and Japanese White-eye were banded, recapture ratios for these two species were lower. These results suggest that during the wintering season, the former three species tend to settle in a restricted area, while the later two species tend to move about over a wide range of forest habitat.

A Procedure of Ecological Data Analysis for Landscape Planning

ICHINOSE Tomohiro

Journal of The Japanese Institute of Landscape Architecture (The Japanese Institute of Landscape Architecture) 58 ( 5 ) 117-120 - 120 1995.03

Research paper (scientific journal), Joint Work, Accepted, ISSN 1340-8984

For the conservation of biota, it is important to analyze ecological data and to make the landscape planning based on this analysis. We propose a procedure of ecological data analysis for landscape planning. The procedure is as follows: 1) Classification of grid cell which are the units of ecological data sampling, based on species composition resemblance by multivariate analysis. 2) Detection of the environmental factors affecting ecological communities. 3) Determination of the major habitat and selection of the sites where more detail survey and analysis are needed. To test the validity of the procedure, two sets of grid cell data of avifauna in Tokorozawa City, Saitama Prefecture were analyzed. The results of classification and discriminant analysis indicated the importance of the Sayama Hills, the Lake Sayama-ko, and some fragmented woodlots as the major habitat of birds. And several sites could be selected for the detail survey and analysis. By the results we are convinced of the validity of this analysis method.

Bird communities on the 20 fragmented woodlots during the wintering and breeding seasons to analyze the factors that influenced the distribution of birds were surveyed in the Tokorozawa City, Saitama Prefecture, Central Japan. Our the results showed that woodlot area is the best predictor of the number of individuals and the species richness. Based on the species composition of bird, the fragmented woodlots were classified into four types: those are core woodlots (type A), woodlots surrounding core ones (type B), woodlots in the field area (type C), and isolated or small woodlots (type D). Besides the woodlot area, the connectivity between woodlots and the landuse surrounding woodlots were recognized as factors influencing avian communities. The necessity of controlling these factors for avian conservation was pointed out.

The relation between wildbirds distribution and land use pattern was analyzed in the Sayama City, Saitama Pref., and the factors which influenced the avifauna were discussed. In this study multivariate methods based on grid cell data were used. Our results showed that avian species were classified into three categories, those are forest species, riparian species, and species occurring between forest and urban area, and that the species richness of forest or riparian species positivery correlated with each habitat area. It appeared that Species belonging to the third category utilized several types of habtat. From the viewpoint of avian conservation, the area of the Sayama City was divided into several parts based on the avifauna and land use should be the key of ecological management.
