Tree Density And Diversity In Hong Kong’S Public Housing Estates: Fromprovision Injustice To Socio-Ecological Inclusiveness., Louis Shing Him Lee, C.Y. Jim, Allen Hao Zhang

Socio-economically underprivileged urban communities might suffer from restricted access to urban forests. Environmental injustice research on urban greenery in Asian cities is lacking. Public housing estates in Hong Kong, accommodating low-income households and over half of the 7.45 million population, were investigated for injustice in tree provision. Two clustering schemes used socio-economic and ecological characteristics to classify 93 estates. Factor analysis of 14 socio-economic variables identified four factors related to deprivation, namely ageing population, overcrowding, working poor with high academic qualifications, and marginalised language minorities. Principal component analysis of six ecological indices returned two components related to tree density and …

Trees offer a range of ecosystem services and remain important in providing human benefits. However, emerging literature questions the long-accepted view of trees being able to improve air quality in urban parks. The aerodynamic effect of trees was identified as a major reason for the change of pollutant distribution in near-road parks, where trees can act as porous barriers and cause localised concentration increase. Although not yet fully developed, planting strategies aiming to mitigate the negative effect of vegetation on air quality should be encouraged in future park design. In this study, we explored the effect of tree planting design …
Species Diversity And Spatial Pattern Of Old And Precious Trees In Macau, Allen Hao Zhang, Po Ying Lai, Chi Yung Jim
Species Diversity And Spatial Pattern Of Old And Precious Trees In Macau, Allen Hao Zhang, Po Ying Lai, Chi Yung Jim

The world's fast pace of urbanization has exerted profound pressure on urban trees. With over 400 years of urban history, Macau has developed an exceptionally high population density and ultra-compact mode, yet it permits survival of interesting and diverse heritage trees. These outstanding living remnants connote special values in history, ecology and botany. In conjunction with commemorative importance, they have been designated as Old and Precious Trees (OPT). This study evaluated the OPT with reference to: (a) species diversity and evenness; (b) spatial distribution; (c) tree dimensions, age and health; and (d) spatial differentiation of tree attributes by four districts …

In China, heritage trees are actively surveyed and reported. Over 300 relevant published articles were reviewed to assess the contents, trends and geographical distributions of the investigations. The majority of the heritage trees studies in China were found in the eastern provinces and published within 2010–2014. Most studies reported surveys on all old trees. For studies focused on single species, Ginkgo (Ginkgo biloba) and Chinese Yew (Taxus chinensis) was most frequently reported. Unlike the champion tree registry in the US and other countries, the tree registry in China emphasized more on the tree age than the size. We then have …
