Trees in Canadian Cities: Indispensable Life Form for Urban Sustainability

Abstract:We argue that a healthy urban forest contributes immensely to the sustainability of cities. The argument is based on a comprehensive array of values elicited from Canadians in several cities. To begin, we define the urban forest as inclusive of all the trees in the city and thus representing the predominant contributor to a city's green infrastructure. Then we enumerate and explain the broad diversity of ways in which urban people value trees in the city. We, thus, show the myriad pathways by which trees contribute positively to any city's social, economic, and ecological sustainability. Following a short summary of the ways in which trees may detract from people's quality of life, we present promising management directions for urban-forest improvement, as we understand the situation in Canada. We conclude that all cities can enhance their sustainability by improving the urban forest.

“…Studies conducted in wilderness areas [55,56] found that people sometimes had negative psychological responses to nature because of fear of crime, encounters with wild animals, and concern about becoming lost in natural settings [57,58], or allergens from pollens and sap in some plants [59]. Studies conducted in urban or suburban spaces found that people feared natural areas when they felt vegetation could be used to conceal criminals [1][2][3]58].…”

The Effect of Biodiversity on Green Space Users’ Wellbeing—An Empirical Investigation Using Physiological Evidence

et al. 2016

Abstract:Promoting ecological health and human wellbeing are two fundamental goals in landscape sustainability. Green spaces are thought to improve users' psychological and physical wellbeing through the contact with nature. However, the results of some studies that rely on self-reports suggest that when the level of naturalness in a green space reaches a certain point, the beneficial effects diminish and in some cases can cause negative responses. We explored this possibility through an experimental study in which we use physiological measures rather than perceptions to assess people's wellbeing. We investigate how people are affected by outdoor settings with varying degrees of biodiversity and whether the correlation between biodiversity and physiological wellbeing is negative or positive. We used multiple measures of insect diversity as an indicator for biodiversity, and biofeedback measures as indicators of wellbeing. Our findings suggest that people are equally affected by more biodiverse and less biodiverse settings. Physiological responses remain largely unchanged when biodiversity increases. This suggests that settings rich in biodiversity will not negatively influence people's physiological wellbeing, and designers and city planners should not hesitate to use ecological best practices in their designs.

“…However, the impact of tree species on public health should also be paid attention in order to facilitate urban sustainability [36][37][38]. As the world's largest developing country with about three decades of double-digit economic growth, China's systemic shift from state socialism to a market economy has been the increasing human-environmental conflicts.…”

Abstract:The growth of urban areas and the impact of urban ecosystems on public health and urban sustainability have been leading issues of both academic and public interest. More than 100 million Chinese people suffer from pollen allergy. Pollen allergy induces bronchitis, bronchial asthma, pulmonary heart disease, and may even be life-threatening. Thus, pollen allergies greatly affect the daily life of individuals. High-resolution WorldView-2 remote sensing data and vegetation distribution features were used to detect the dominant tree species in the study area and obtain canopy distribution information on different tree species. In this way, the sources of pollen from different tree species were identified. Using remote sensing technology, the overall accuracy of tree species recognition for the study area exceeds 86%. Most plants in the study area flower during the spring, so the pollen allergenic risk zones are extensive during spring and sparse in fall. Based on the spatial ranges of pollen dispersal during different seasons, areas were identified that might contain pollen concentrations detrimental to pollen-sensitive individuals.
