“…In large cities these measures (e.g. the ecological restoration of urban green systems) are usually much more costly and difficult to implement (Kong et al 2010;Yu et al 2012). In small cities such measures may be developed at the earliest stage of city development and include: the exclusion of habitat blocks from development, development of a system of corridors connecting green areas to each other and with rural areas, and statutory protection of the most valuable natural sites.…”

Fundamental principles regarding urban biodiversity are based on studies conducted in large cities. However we cannot know whether the same phenomena occur in smaller cities or how small cities affect biodiversity. Small cities are an inherent element of urbanization and in the future, most global urban growth is expected to take place in small and mediumsized cities. Understanding the effects of small cities on biodiversity will be an important aspect in planning urban land expansion. Our study examined the effects of a small city on communities of small ground-dwelling mammals on 41 sites arranged in a four step gradient of urbanization. In 6700 trapdays, we caught 2333 individuals comprising 15 species. In the downtown area the same phenomena as those described for large cities were observed: a reduction in species richness and diversity, a decline in the abundance of urban sensitive species and an increase in synurbic species. However, in contrast to large city studies, green areas outside the downtown area did not differ from rural sites in small mammal population parameters. This phenomenon of relatively unchanged fauna outside the downtown area shows that small cities have the potential to maintain a high level of diversity of small grounddwelling mammals if appropriate planning of further building expansion is implemented. More studies of small cities are needed to better assess their impact on biodiversity. This knowledge can then be applied in better planning for urban wildlife. Generalizations based solely on large city studies are inadequate and may lead to incomplete or inappropriate conservation strategies for small cities.

“…Most previous research has focused on analysis or simulation of the movements of specific wild species [56][57][58][59][60]. Measuring functional connectivity involves calculating the time and distance over which a specific species searches for a new habitat patch using various techniques, such as random walk modeling [45,61,62], network analysis [55,63], gravity modeling [64], and the least-cost path method [65]. The random walk is a simple model of diffusion processes that has been used to study the movements of wildlife [45].…”

“…However, this method is unable to visualize the results using GIS. Gravity modeling and network analysis have become established as promising ways to efficiently explore and analyze landscape or habitat connectivity [63,64]. Network analysis emerged as a branch of operational research concerned with network structure and network optimization with the help of graph theory [55].…”

“…Network analysis emerged as a branch of operational research concerned with network structure and network optimization with the help of graph theory [55]. Gravity modeling can be used to identify relatively high-quality habitats and to choose the best opportunities for maintaining and restoring connectivity [64]. However, these methods are yet to be fully explored, and integrating landscape metrics in the planning of urban ecological network is complicated.…”

“…The least-cost path method has been used to identify paths that connect ecologically valuable areas by calculating all cost-surfaces pertaining to wildlife mobility for ecological planning [7,69]. Related research involves analyses of network patterns of local communities [70], road construction and traffic scenarios in industrial areas [71,72], plans for urban green networks and coastal eco-networks [73,74], and green networks through connectivity assessments of wildlife [64,75,76]. In this study, the least-cost path method is used to select the optimal area for replacement wetland that can ecologically compensate for a cost area.…”

An Integrated Approach to Mitigation Wetland Site Selection: A Case Study in Gwacheon, Korea

This paper presents an integrated approach to mitigation wetland site selection using functional landscape connectivity and landscape structure. This approach enables landscape designers to evaluate the relative priorities of mitigation wetland areas based on functional landscape connectivity and wildlife mobility, as well as landscape structure, composition, and configuration. The least-cost path method is used to evaluate candidate sites for mitigation wetlands with regard to wildlife movement. A set of assessments for landscape indices using FRAGSTATS was applied to identify suitable mitigation wetland areas on the basis of landscape connectivity, composition, and configuration. The study was conducted in Gwacheon, Korea, where there are plans for regional development that will change the landscape. In the first step, a group of 14 candidate sites is identified via analysis of functional landscape connectivity using the least-cost path method. In the second step, candidate mitigation wetland areas are ranked according to landscape connectivity and composition. The five mitigation wetland areas that were found to be suitable were analyzed based on landscape configuration at the class level. This study demonstrates OPEN ACCESSSustainability 2015, 7 3387 that functional landscape connectivity and landscape structure are important aspects to consider when identifying suitable sites for mitigation wetland planning and restoration.
