Although cultural interests are described in the Bundesnaturschutzgesetz (Federal Nature Conservation Act) at the same hierarchical level as ecological interests, there exists in Germany an influential movement that understands nature conservation exclusively as an ecological-scientific task. In connection with this understanding, the fallacy that objectively compelling maxims for political action would result from ecological data […]

Nature Conservation, Forestry, Landscape Architecture and Historic Preservation: Perspectives for a Conceptual Alliance
Stefan Korner Institute of Ecology, Technical University Berlin Introduction Administrative nature conservation in Germany, which is predominantly scientifically and ecologically based, must admit to a lack of public acceptance (Politische Okologie 1995; Wiersbinski et al. 1998; Der Rat von Sachverstandigen fur Umweltfragen 2002; Korner et al. 2003). (Volunteer nature conservation organizations are not the subject […]
Toward establishing ecological network planning for wintering bird species
The results of this study indicate the following points for ecological network planning in Japanese cities. Protection of large core woodlands. Of course, large habitats are important for not only wintering birds but also breeding birds. In most Japanese cities, there are few large woodlands and the proportion of green coverage is lower than that […]
Relationship between the number of species and the area of the park
Many studies (e. g., Martin 1983) have indicated a relationship between the number of species and the size of habitat for isolated habitats. However, I did not find a significant correlation between the number of bird species and the area of urban park, but there was a significant correlation between the number of species and […]
Classification-tree analysis
The results of the classification-tree analysis are shown in Fig. 5. First, urban parks were divided into two branches according to the proportion of surrounding woodland within 500 m. All urban parks of type B and two parks of types A and C were classified into a branch for which the proportion of surrounding woodland […]
Regression analysis
As a result of bird censuses, 21 species and 1,825 individuals were recorded. The most species (13 species) were observed in the largest urban park (3.4 ha). No significant correlation between the number of species and the area of urban park was detected (p=0.1; Fig. 2), though a significant correlation between the number of species […]
Vegetation cover within the parks and land use outside the parks
The area of land covered with shrubs and taller trees within the urban park (= area of vegetation cover) was calculated using aerial photographs taken in 1998. Surrounding land uses were computed with GIS (geographic information systems) using topographic maps (1:2,500) and the aerial photographs. All land uses were classified into nine land-use types: rice […]
Vegetation structure measurements
In each park, a 50 m transect was established, located essentially at random but covering all representative structures. Vegetation structure and composition were recorded at 25 points (spaced at 2 m intervals) along the line. The presence or absence of vegetation within a circle of 0.60 m diameter was recorded at each point, at thirteen […]
Material and methods Study area
The study area was the southern part of Nishinomiya City, Hyogo Prefecture, central Japan (Fig. 1), located between Osaka and Kobe. Commercial and residential land uses are dominant in the area, though there are many urban woodlands consisting of fragmented forests, shrine and temple forests, riparian forests, urban parks and so on. Twenty urban parks […]
Ecological Networks for Bird Species in the Wintering Season Based on Urban Woodlands
Tomohiro Ichinose Institute of Natural and Environmental Science, University of Hyogo Background We can watch many birds in urban woodlands. Recently urban woodlands have been considered an important habitat for bird species, and many studies have been conducted in order to identify which environmental factors of urban woodlands and open space are necessary for bird […]
