“…Where natural areas are deficient, they could be nurtured with the careful site and soil preparation and native plant species to emulate regional wooded ecosystems (Johnston 1990;Lee and Thompson 2005). Disturbed natural areas could be repaired or restored by enrichment planting and elimination of undesirable elements to foster reconstitution of natural ecosystem (Borgmann and Rodewald 2005).…”

Urban greening contributes notably to quality of life and ecosystem services in cities. Compact cities in developing and developed countries are commonly beset by greenspace deficit. Based on literature review supplemented by field studies in different cities, a sustainable urban greening strategy is proposed. Urban renewal and new developments without a greening vision could miss the opportunities to bring relief. The public and private sectors can join hands to insert plantable spaces into the urban fabric. Urban greenspaces (UGS) with good connectivity forming a green network to permeate the city constitute the hallmarks of a naturalistic design. Preservation and creation of natural areas with rich biodiversity offer a new dimension to UGS design. Greening benefits could be expressed in economic terms to complement conventional ecological-environmental emphasis. Outstanding trees could receive high-order conservation efforts, and trees in construction sites warrant enhanced protection. Tree transplanting demands an overhaul in concepts and skills. Improving roadside tree planting and maintenance offers a cost-effective way to upgrade the townscape. Ameliorating widespread soil limitations could remove a major hindrance to tree growth. Innovative ideas of development right transfer, street pedestrianization, river and canal revitalization, green roofs and green walls could mobilize hitherto underused plantable resources. Lacking appropriate institutional setup and scientific capability pose intractable bottlenecks. Innovative public policies and greening technologies are needed for sustained improvements. Amalgamating natural and social sciences in a multidisciplinary approach and reinforcing the link between science and public policies could overhaul greening.

“…This trend in benefit mapping studies is linked to the increased research interest in multifunctional land use and ecosystem services, and the increased availability and accessibility of computers, modelling software and (georeferenced) data. These developments also explain why in more recent years there has been a strong increase in the number and diversity of studies looking at the efficiency of spatial targeting of land use policy interventions for the provision of non-market goods (Yang et al, 2003;Park et al, 2004;Groeneveld et al, 2005;Lant et al, 2005;Lee and Thompson, 2005;Messer, 2006;Bailey et al, 2006;Saroinsong et al, 2007). These studies demonstrate time and again that better spatial targeting can in principle result in better value for money.…”

“…Conversely, heavily disturbed systems should be given lowest priority, as they may not recover without massive human intervention (Goodwin et al 1997). Restoration actions include the use of riparian vegetative buffer strips (Osborne and Barling and Moore 1994;Parkyn et al 2003), reducing patch perimeter-area ratio (Lee and Thompson 2005), road decommissioning (Roni et al 2002;Switalski et al 2004), NCD, and channel reconfiguration (Roni et al 2002;Parkyn et al 2003). All model-predicted candidate sites for restoration need to be field-checked and must account for the degree of community support, quality of surroundings and upland areas, and the problem being mitigated.…”

Landscape scale assessment of stream channel and riparian habitat restoration needs

Human modifications of streams and rivers have caused extensive stream channel and riparian degradation. Cost-effective, rapid assessment tools can be used to better manage such areas by identifying the status of habitats for restoration planning and protection. We used a spatially explicit, reach-scale geographic information system modeling strategy to examine stream channel and riparian condition and prioritize restoration actions. The stream channel condition index uses information on land use, road and railroad density, and sinuosity. The riparian condition index uses calculations of percent forest, patch density, and convexity based on land cover in the floodplain. Reaches were classified into restoration categories based on stream channel and riparian condition model results, land ownership, slope, position in the subwatershed, and adjacency to high-quality habitat. We compared modeled restoration priority rankings with those in the management plan for the East Credit subwatershed in Ontario, Canada. Predicted stream channel restoration priority rankings matched field-based classifications for 86% of the reaches in the East Credit subwatershed. Predicted riparian restoration priority rankings matched fieldbased classifications for 81% of the reaches. Our methods replicate with fairly good accuracy the results obtained using intensive field surveys and stakeholder input. Managers can use these cost-effective strategy development tools to identify candidate reaches for further study and prioritize stream channel and riparian restoration actions over large regions.
