Dr. Ellis is a professor of landscape architecture at the University of Maryland. His research centers on finding ways to integrate human habitat and wildlife habitat with co-benefits to each. He held previous appointments at the University of Michigan and Texas A&M University. He is an Academy Fellow for the Council of Educators in Landscape Architecture where he served on the board of directors for ten years.
We investigated the effects of pedestrian environments on parents’ walking behavior, their perception of pedestrian safety, and their willingness to let their children walk to school. This study was a simulated walking environment experiment that created six different pedestrian conditions using sidewalks, landscape buffers, and street trees. We used within subjects design where participants were exposed to all six simulated conditions. Participants were 26 parents with elementary school children. Sidewalks, buffer strips, and street trees affected parents’ decisions to: walk themselves; let their children walk to school; evaluate their perception whether the simulated environment was safe for walking. We found that the design of pedestrian environments does affect people’s perceptions of pedestrian safety and their willingness to walk. The presence of a sidewalk, buffer strip, and street trees affected parents’ decision to walk, their willingness to let their children walk to school and perceived the pedestrian environment as safer for walking. The effects of trees on parents’ walking and perception of pedestrian safety are greater when there is a wide buffer rather than a narrow buffer. It was found that parents are more cautious about their children’s walking environments and safety than their own.

Ecosystem services depend on the interrelation between people and the environment, and people are increasingly recognizing the social value of ecosystem services. Based on humans needs related to the values of ecosystem services, riparian greenways, properly planned and managed for resiliency, could provide great opportunities for social ecological change and transformation toward sustainability. We focus on the ecosystem service values of such greenways based on resilience in urban communities. The purpose of this study is to assess the social value of ecosystem services for resilient riparian greenway planning and management based on a survey of residents living near the Yangjaecheon riparian greenway in Gwacheon, South Korea. First, cluster analysis was performed with data from 485 completed surveys to identify different groups of respondents. Importance-performance analysis (IPA) was then applied to develop planning and management guidance for the riparian greenway based on group characteristics. Two distinct groups were identified: the Strong Social Value of Ecosystem Services group and the Neutral Social Value of Ecosystem Services group. Different distributions were found between the two groups based on gender and residency period, and significant differences were also found for age and familiarity with the riparian greenway. The results show what each group perceived to be important and how well the riparian greenway met their expectations regarding ecosystem services. These results indicate the perceived value of ecosystem services on the basis of the group characteristics, helping establish the direction for resilient riparian greenway planning and management approaches.

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 that functional landscape connectivity and landscape structure are important aspects to consider when identifying suitable sites for mitigation wetland planning and restoration.
