Urban forestry is an important green infrastructure strategy because healthy trees can intercept rainfall, reducing stormwater runoff and pollutant loading. Surface saturation storage capacity, defined as the thin film of water that must wet tree surfaces before flow begins, is the most important variable influencing rainfall interception processes. Surface storage capacity is known to vary wid...

In 1990, the Chicago Academy of Sciences held a conference, Sustainable Cities: Preserving and Restoring Urban Biodiversity, which led to the publication of a book entitled The Ecological City (Platt et aI., 1994). This symposium differed from others on cities at that time by focusing principally on cities as habitats for biodiversity. The thrust of the symposium was that interactions between p...
Background and Purpose: Climate change has an impact on economic and natural systems as well as human health. These impacts are particularly visible in urbanised areas. Urban forests, which are one of the main natural features of the cities, are threatened by climate change. Generally, the role of forests in combating climate change is widely recognised and its significance is recognised also i...
Many of us feel intuitively that having access to nature in urban environments is important for our quality of life. The evidence base supporting this claim has grown considerably in recent years, with high profile studies highlighting the links between access to greenspace/having views of nature and health and wellbeing. Physical activity in green environments is increasingly seen as a valuabl...
Private forestlands in the United States face increasing pressures from growing populations, resulting in greater numbers of people living in closer proximity to forests. What often is called the “wildland/urban interface” is characterized by expansion of residential and other developed land uses onto forested landscapes in a manner that threatens forestlands as productive socioeconomic and eco...
