Methane uptake in urban forests and lawns.
The largest natural biological sink for the radiatively active trace gas methane (CH4) is bacteria in soils that consume CH4 as an energy and carbon source. This sink has been shown to be sensitive to nitrogen (N) inputs and alterations of soil physical conditions. Given this sensitivity, conversion of native ecosystems to urban, suburban, and exurban managed lawns thus has potential to affect ...
متن کاملNitrogen retention in urban lawns and forests.
Lawns are a dominant cover type in urban ecosystems, and there is concern about their impacts on water quality. However, recent watershed-level studies suggest that these pervious areas might be net sinks, rather than sources, for nitrogen (N) in the urban environment. A 15N pulse-labeling experiment was performed on lawn and forest plots in the Baltimore (Maryland, U.S.A.) metropolitan area to...
متن کاملLawns and Ground Covers in Landscape Design
In suitable growing conditions, the grasses are one of the well lawn covering materials due to uniform in color and texture, soft and resilient, easy to take care of. In many areas, grasses can provide a surface that maintenance frees than paving. They can be walked on, sat on and used for many outdoor activities and sport activities such as; football, soccer, volleyball and related practices. ...
متن کاملModeling Carbon Sequestration in Home Lawns
Soil organic carbon (SOC) sequestration and the impact of carbon (C) cycling in urban soils are themes of increasing interest. A model was developed to investigate the potential of C sequestration in home lawns. The model contrasted gross C sequestered versus the hidden C costs (HCC) associated with typical lawn maintenance practices. The potential of SOC sequestration for U.S. home lawns was d...
متن کاملEcology of grazing lawns in Africa.
Grazing lawns are a distinct grassland community type, characterised by short-stature and with their persistence and spread promoted by grazing. In Africa, they reveal a long co-evolutionary history of grasses and large mammal grazers. The attractiveness to grazers of a low-biomass sward lies in the relatively high quality of forage, largely due to the low proportion of stem material in the swa...
