The recognition of this hierarchical linkage among healthy urban forests and the effectiveness of broader ecosystem protection goals (e.g., maintaining biodiversity and wildlife corridors), highlights the need for scientists and policymakers to gain a better understanding of the socio-spatial dynamics that are associated with tree canopy health at different scales (Wu 2008). All Rights Reserved. A "Tree Explains It All". Urban foresters plant and maintain trees, support appropriate tree and forestpreservation, conduct research and promote the many benefit… "Transforming inner-city landscapes – Trees, sense of safety, and preference.".  By examining coyote scat and using stable isotope analysis, it was estimated that about 22% of the scat or 38% of the urban coyote diet was from human-created sources. However, the distribution of urban tree cover and the beneﬁ ts of urban forests vary across the United States, as do the challenges of sustaining this important resource. This is often due to the failure of municipalities to integrate trees and other elements of the green infrastructure into their day-to-day planning and decision-making processes (American Forests 2002). Planned connections of green spaces encompass not only parks and gardens, but also landscaped boulevards, river and coastal promenades, greenways and even simple street-side tree boxes. Urban forests provide numerous environmental and health benefits to the people of Canada. Egleston, N.H. 1878.

Influence of Trees on Residential Property-Values in Athens, Georgia (USA) - a Survey Based on Actual Sales Prices. Reducing Air Pollution Through Urban Forestry. In fact, over 140 million acres of America’s forests are located in cities and towns, and these trees provide essential benefits for humans and improved habitats for urban wildlife. At this time, parks and trees were not necessarily seen as a way to allow urban dwellers to experience nature, but more of a means of providing mechanisms of acculturation and control for newly arrived immigrants and their children (e.g., areas to encourage "structured play" and thus serve as a deterrent for youth crime) (Pincetl and Gearin 2005). The many identified problems of street trees are overcome with care by designers. The urban environment can present many arboricultural challenges such as limited root and canopy space, poor soil quality, deficiency or excess of water and light, heat, pollution, mechanical and chemical damage to trees, and mitigation of tree-related hazards. Inadequate space is allowed for the root system. (2003).  Forestry experts then became more involved in forest and green services management as localities and national forest services became responsible for these areas.. Olympia, WA: Washington State Department of Natural Resources.  Only one year later department head, Dean Sisam, applied the term to the previously known courses of “arboriculture and parks management”, three years following that the university began creating diplomas for urban forestry; producing seven graduates by 1982.

Urban forests make up a significant amount of America’s tree canopy. Scandinavian Journal of Forest Research, 28(1), 49–63. The development of tree ordinances emerged largely as a response to the Dutch Elm Disease that plagued cities from the 1930s to 1960s, and grew in response to urban development, loss of urban tree canopy, and rising public concern for the environment (Wolf 2003). care of trees, forests, green space and related resources in and around cities and communities for economic, environmental, social, and public health benefits for people.  It allows aspects of the forest, such as ecosystem services and benefits, species composition, canopy distribution, and health, to be monitored and predicted for current and future management needs. It is estimated that there are around 3.8 billion trees in urban areas around the United States, equating to $2.4 trillion in overall structural value.  Data from urban forest assessments can prove to be useful in not only providing information for foresters but in quantifying benefits that can show members of the public the importance of preserving and protecting trees in urban forest settings. As society has progressed and the technology has improved, the roles of tree wardens have adapted. , The City of Denver Department of Parks and Recreation website hosts interactive online tools that allow residents to view the financial impact to their neighborhoods directly related to healthy tree planting. , Urban forest related events such as planting festivals can significantly reduce social isolation problems, enhance people's experience and raise environmental awareness. If either of these approaches are infeasible, you may use the standard survival factors for urban trees provided in Table 2. New York: Springer. To Olmsted, unity between nature and urban dwellers was not only physical, but also spiritual: "Gradually and silently the charm comes over us; the beauty has entered our souls; we know not exactly when or how, but going away we remember it with a tender, subdued, filial-like joy" (Beveridge and Schuyler 1983 cited in Young 2009:320).

While urban lumber may not be as high of a grade quality as forest grown lumber, these products are suitable for smaller projects such as woodworking and artisan furniture. The top-down approach utilizes aerial and satellite imagery to discern canopy cover, plantable space, and impervious surfaces at a low cost. This includes a great deal of planning and following countless regulations.  Trees may live a long and healthy life if they continue to receive proper management in the form of maintenance and pruning, which sustains the value of the urban forest. However, the uneven distribution of healthy urban forests across the landscape has become a growing concern in the past 20 years.
