Urban trees and biodiversity in Cork city
Biodiversity is poorly quantified in urban landscapes and is not effectively incorporated into urban planning and policymaking. Land-use change (e.g., urbanisation) is one of the key drivers of biodiversity loss. Furthermore, urbanisation is expected to increase from 50 to 70% by 2050. The CSO …

HOW TO REDUCE TRANSPLANT STRESS IN URBAN TREES
Urban vegetation is nowadays recognized as a key component of the adaptation and mitigation strategies against climate change. In this context, municipalities and public services are promoting large scale tree planting programs in urban environment. However, these programs frequently experience …

Cooling Machines: Exploring the Heat Mitigation Effect of Urban Trees with Computer Vision
… climate change on cities become more pronounced, urban authorities are under pressure to prepare existing streetscapes for increased levels of heat stress. While many aspects of existing urban morphology have an impact on heat exposure (e.g. sky view factor, glazing levels, facade materials), they …

Epidemiology and population structure of Xylella fastidiosa, the causal agent of bacterial leaf scorch, among urban trees in the District of Columbia
A survey of urban trees affected by bacterial leaf scorch caused by Xylella fastidiosa was conducted in the District of Columbia during 2012 and 2013. Disease occurred most frequently with Quercus palustris, Q. rubra, Ulmus americana, and Platanus occidentalis. Eight other symptomatic and five …

Development of Urban Tree Growth Models Based on Site and Soil Characteristics
Trees provide numerous benefits crucial to urban environments, yet poor growing conditions often prevent trees from reaching their genetic potential for growth, longevity, and ecosystem function. To overcome these limitations, greater understanding of tree growth in the urban environment is needed. …

The governance of local climate commons
… Area in Metropolitan Sydney, I examine how urban trees and vegetation, accessible to both public and private interests, represent a local climate commons that provides climate adaptation benefits such as heat regulation to residents, visitors and ecological communities. Drawing on empirical …

Influence of Tree Planting Program Characteristics on Environmental Justice Outcomes
Urban trees provide a variety of benefits to human physical and mental health. However, prior research has shown that urban tree canopy is unevenly distributed; areas with lower household incomes or higher proportions of racial or ethnic minorities tend to have less canopy. Urban tree benefits are …

Planning the urban forest to enhance urban resilience
… identify extreme heat as a significant threat to urban areas. This is largely due to the impact of heat on human health, their livelihoods, and access to resources (USGCRP, 2018; IPCC, 2014). Both the IPCC (2014) and the USGCRP (2018) identify afforestation as a key strategy for moderating the …

Street Trees as a Source of Timber in Washington, DC
Recycling felled urban trees that are hazardous or unhealthy is increasingly viewed as a viable practice to control disposal costs, promote environmental practices, and support local commerce. Wide spread waste wood utilization is encumbered by numerous presumptions about wood quantity, quality, …

Inventorying trees in an urban landscape using small-footprint discrete return imaging lidar
Automation of urban tree inventory using remote sensing is needed not only to reduce inventory costs but also to support carbon accounting for urban planners and policy-makers. However, urban areas are heterogeneous and complex, and a more sophisticated approach is needed for using remote-sensing …

Designing With Climate: Using Parking Lots to Mitigate Urban Climate
Urban areas are known to have different climatic conditions than their rural counterparts including higher temperatures, greater wind speeds, and increased precipitation otherwise known as urban heat islands, urban wind, and urban precipitation. These phenomena are all caused by the design and form …
