Conservation in the suburban & urban landscape
Transcript of Conservation in the suburban & urban landscape
design by Dóri Sirály for Prezi
Urban to Suburban Sprawl
Wilderness area and farmland adjacent to larger cities has been converted to suburban landscape.
Negative Impacts of Suburbia:
Alteration or loss of wetland/riparian areas
Increased Exotic Species
Pollution of Groundwater
Increased Production of Carbon Dioxide
Suburban planning and conservation
Integrating ecological and aesthetic values into planning and management of developed areas
Characteristics of an ecologically viable suburban landscape:
large patches of undisturbed natural vegetation
connectivity between patches
natural vegetation corridors along water courses
a heterogeneous distribution of nature throughout the community
The need for urban conservation planning:
Conservation focus has recently begun shifting to recognize rapid urbanization problem
"the number of urban residents is growing by nearly 60 million every year" WHO
Must look at non-traditional open spaces & now new Push for “open-spaces” as potential habitat
Must re-develop existing spaces in a more ecologically friendly way
Large population directly leads to development pressure in terms of housing, infrastructure and industry
Greenways (habitat patches)
3 MAJOR TYPES:
“1) ecologically significant corridors,
2) recreational greenways,
and/or 3) greenways with historical and cultural values” (Fabos, 2004)
Most important predictors of species presence:
distance between greenways
habitat quality within these areas
Infill Development/Smart Growth
Redevelopment of existing development
AKA “new urbanism”
“Not designed for single use, low density, domination by automobiles & highways – rather it creates neighborhoods & districts that have mixed use, residents of mixed income and diversity, and it serves pedestrians & cyclists”
