Readings Discussed: Steed/Fisher, Tree City Stds, Urban Forest Sustainability, Tree Canopy Goals
SUMMARY:
The topic of urban forestry has always been interesting and appealing to me. The idea of integrating nature into human built environments is seems logical and attainable concept. The Steed/Fisher article addresses the issue of street trees. Street trees are loosely defined as natural space and tree

trees themselves and the spaces on which they reside are seemingly better defined as CPRs." They go on to describe that access to street trees can also be rivalrous. Shared (perceived) ownership of tree space can result in excessive paving, driveway expansion, road expansion and sidewalk expansion. When these other interests are presented, they are often favored and viewed as more beneficial than the tree area. Lastly, the two authors present the interesting predicament of legal liability of street trees. They present cases where city governments have been sued over pedestrians being injured by falling branches, and motorists getting in accidents due to tree-obstructed street signs.
The other 3 articles echo the Steed/Fisher article by presenting specific programs and plans for urban tree development. The Tree City USA article outlines the requirements a city must achieve before it can be denoted a Tree City. They consist of an establishment of a tree board or department, a tree care ordinance, a community forestry program, and an Arbor Day observance and proclamation. The next article talks about the American Forests organizations plans for and explanation of tree canopy goals. It explains the importance of urban forestry. Lastly "A MODEL OF URBAN FOREST SUSTAINABILITY" is just that, a plan for how cities can develop sustainable tree areas. This plan's central themes are a healthy tree and forest resource, community-wide support and a comprehensive management approach.
COMPARISON
The major difference between the articles was their tone. The Steed/Fisher article was an academic article that sought to clarify why there was confusion about street trees. The Urban Forest Sustainability article was also academic in nature, but provided more of a sustainability outline than the Steed/Fisher article did. The other two articles were shorter and seemed to be more of reference-type documents. Both the Steed/Fisher and Sustainability articles agreed on the importance of monitoring and human intervention within the urban forestry realm. Both also thoroughly explained the benefits of urban forestry. I guess another difference would be that the Steed/Fisher article focused on exclusively "street trees" while the other articles talk about a wider notion of urban tree cover.
QUESTIONS
After reading the Tree City USA requirements, I wondered why exactly cities would want to carry that title

Another notion I thought about was the concept of ownership. Though the Steed/Fisher article discussed it, I still wonder if it is better for urban trees to be publicly or privately owned. When I say publicly owned, I mean owned and maintained by the government. Other looser, community group and NGO owned options are possible, but probably lack funding to do an adequate job. I realize that you can apply the public/private question to many things, including utilities, military, healthcare, et cetera. Though the debate still rages on, which ownership option is better? The government collects funds through taxes, but is often burdened by the snails pace of bureaucracy. Many argue that privatization is the most efficient way to achieve progress, though I sometimes doubt its equity.
