ABSTRACT The world's human population is becoming concentrated into cities, giving rise to concerns that it is becoming increasingly isolated from nature. Urban public greenspaces form the arena of many people's daily contact with nature and such contact has measurable physical and psychological benefits. Here we show that these psychological benefits increase with the species richness of urban greenspaces. Moreover, we demonstrate that greenspace users can more or less accurately perceive species richness depending on the taxonomic group in question. These results indicate that successful management of urban greenspaces should emphasize biological complexity to enhance human well-being in addition to biodiversity conservation.

    ABSTRACT: Urban green spaces are very important for a country to maintain its socio-environmental balance. But in most developing countries these UGSs were on the wane. Not only their count was decreasing, but it was even difficult to maintain and sustain the existing facilities. Pakistan as a developing country is facing the same problem. This study was carried out in Lahore; the 2 nd largest city of Pakistan to address the same problem on micro scale. Gulberg Town with its 15 union councils was taken as a case study. The results produced by using GIS software showed that amount of urban green spaces present in Gulberg town were not sufficient to cater for the need of the people. The results also showed that areas in south was having more green spaces as the phenomenon of urban development is prominent in that part of the city. The northern areas, as a part of old city, were lacking in urban green spaces. The results exhibitis that the per capita green space was far less in Gulberg town-Lahore as suggested by international standards set forth for a sustainable city. This imbalance in our urban life poses a real challenge for the policy makers, city managers as well as for city dwellers.

    ABSTRACT: As our world becomes increasingly urbanized, cities are often where we come into contact with the natural world—not just in parks and urban nature preserves, but in more familiar places like residential yards. We conducted bird surveys and social surveys in Chicago-area residential landscapes near forest preserves (primarily in middle- and high income areas) to examine residents’ perceptions of the birds that co-inhabit their neighborhoods and the relationship of those perceptions with characteristics of the bird community. We found that residents value many aspects of neighborhood birds, especially those related to aesthetics and birds’ place in the ecosystem. Our results indicate that while birds were generally well liked and annoyances were minor, several common and visible urban species, such as the House Sparrow (Passer domesticus), European Starling (Sturnus vulgaris), and Blue Jay (Cyanocitta cristata), may attract attention for their negative qualities, such as their sounds and effects on personal property. The results also indicate that residents’ valuations of ecosystem services are linked to their perceptions of bird species richness rather than the actual species richness, and people may perceive only a subset of the birds in their neighborhoods. Although birds provide many important ecosystem services, perhaps one of their most important roles in cities is as a relatable and likable connecting point between city dwellers and the broader environment.
