OBJECTIVES Parks provide places for people to experience nature, engage in physical activity, and relax. We studied how residents in low-income, minority communities use public, urban neighborhood parks and how parks contribute to physical activity. METHODS In 8 public parks, we used direct observation to document the number, gender, race/ethnicity, age group, and activity level of park users...

BACKGROUND Toxocariasis is an important disease caused by the larvae of parasitic worms such as Toxocara canis and T. cati. Public parks can be the source of toxocariasis for small children. This survey was conducted to determine the prevalence of Toxocara spp. ova in parks of Mashhad and Khaf northeastern Iran. METHODS In this descriptive cross-sectional study, performed in November 2011 to ...

Green space is important for the maintenance of the ecological dimension of a sustainable urban landscape. Therefore, in order to figure out the relationship between the greening of urban parks and bird diversity, we used 5 avian ecological diversity indexes, such as Species richness, Abundance, ShannonWeiner diversity index, Evenness, and Margalef’s richness indices, to evaluate the functional...

We measured soil properties, carbon and nutrient (nitrogen, phosphorus) pools, ambient and potential denitrification, and phosphorus sorption index (PSI) in natural depressional wetlands and depressional wetlands restored through the U.S. Department of Agriculture (USDA) Wetland Reserve Program. We measured the same suite of variables in natural and USDA Conservation Reserve Program-restored ri...

Splash parks have been associated with infectious disease outbreaks as a result of exposure to poor water quality. To be able to protect public health, risk factors were identified that determine poor water quality. Samples were taken at seven splash parks where operators were willing to participate in the study. Higher concentrations of Escherichia coli were measured in water of splash parks f...

urban green spaces and parks are important land use of cities which promote quality of life by providing facilities for leisure and also play a crucial role in social cohesion and participation due to their socio-economic and environmental functions. hence the distribution of such spaces is very important in cities. however the zone of 3 in tehran has a relative appropriate green space per capi...

Societal constraints often limit full process restoration in large river systems, making local rehabilitation activities valuable for regeneration of riparian vegetation. A target of much mitigation and restoration is the federally threatened Valley elderberry longhorn beetle and its sole host plant, blue elderberry, in upper riparian floodplain environments. However, blue elderberry ecology is...

Rinne, J.N., 1990. The utility of stream habitat and biota for identifying potential conflicting forest land uses: Montane riparian areas. For. Ecol. Manage., 33/34: 363-383. Investigations since 1960 on the effects of land-management practices on riparian-stream systems often have produced contradictory results. Inconsistencies have occurred, in part, because of efforts that have not been tota...

Riparian areas link streams with their terrestrial catchments and decrease water pollution by trapping sediments from upland sources before they reach streams or lakes. Livestock grazing in riparian areas is a controversial practice. If not properly managed, cattle can cause degradation to both the riparian zone and adjacent water body. Vegetative, soil microtopographical, microchannel and hydr...

As plants have been shown to accumulate organic compounds from contaminated sediments, there is a potential for long-lasting ecological impact as a result of contaminant accumulation in riparian areas of wetlands, particularly the accumulation of non-biodegradable contaminants such as perfluorooctanoic acid (PFOA). In this study, commonly found riparian wetland plants including reeds, i.e., Xan...
