Tennessee's Urban Forests Valued in the Billions

March 15, 2012

Nasheville, TN -- Tennessee's urban forests, currently valued at about $80 billion, also provide almost $650 million in benefits such as carbon storage, pollution removal, and energy reduction according to a new U.S. Forest Service report.

The authors of Urban Forests of Tennessee, 2009 found there are 284 million trees in urban areas in the state, with canopies covering 33.7 percent of 1.6 million acres of urban area. Those urban forests provide an estimated $204 million per year in pollution removal and $66 million per year in energy savings. The study is the first of its kind in Tennessee.

"This report, for the first time, puts a face on the urban forest resource and what it means to the state in terms of economic and environmental value," said Steven Scott, Tennessee State Forester and head of the Tennessee Division of Forestry, which collected the data for the report. "Perhaps the most significant finding is the immediate impact of urban trees on the use of energy, the savings we get as a result of shade near homes, businesses and industrial areas."

David Nowak, Northern Research Station project leader and research forester, led the pilot study, which sampled trees in all the state's urban area and analyzed their value using a model developed by the Forest Service.

"Urban forests make our cities healthier, more vibrant places to live," said Nowak. "They provide healthy outdoor spaces for our kids, they clean our air and water, and -- as this study shows -- they provide tremendous economic benefits. We must continue our work to protect these critical natural resources."

There are more than 100 million acres of urban forest across the U.S., but a recent study shows that many are in decline.

The Tennessee report includes an extensive assessment of urban forest health, providing information about present damage and potential risks. In addition to nonnative invasive plants, Tennessee urban forests face risks from exotic pests that include the recently discovered thousand cankers disease, which impacts black walnut; hemlock woolly adelgid, which kills eastern and Carolina hemlocks; the Asian longhorned beetle, which kills a wide range of hardwood species; and the emerald ash borer, which decimates ash trees. This last insect was recently documented in East Tennessee.

The Forest Service Inventory and Analysis and Community Forestry Programs partnered with Tennessee Division of Forestry and researchers from the Forest Service Northern Research Station and SRS on the project.

Forest Service Study Finds Urban Trees Removing Fine Particulate Air Pollution, Saving Lives
In the first effort to estimate the overall impact of a city's urban forest on concentrations of fine particulate pollution (particulate matter less than 2.5 microns, or PM2.5), a U.S. Forest Service and Davey Institute study found that urban trees and forests are saving an average of one life every year per city. In New York City, trees save an average of eight lives every year.

Urban Forest: Images of Trees in the Human Landscape (Sierra Club Books Publication)

Urban Forest: Images of Trees in the Human Landscape (Sierra Club Books Publication)
by David Paul Bayles (Photographer)

Beyond their aesthetic and utilitarian importance, urban trees seem to fill a deeper human need. Perhaps they are reminders of the inexorable cycles of the natural world. Perhaps they serve as eddies and rills of slowness and sureness within the frantic rush of our urban environment. For more than two decades, photographer David Paul Bayles has been making images of trees in cities and suburbs - places of tension, as he puts it, between 'what we build and what we grow'. This beautifully designed and produced volume showcases his extraordinary vision of urban trees and their often precarious, sometimes triumphant place in the human landscape.Initially drawn to his subject by 'the balance and harmony and beauty between the manmade structure and the tree', Bayles has also found and...

Urban Forests, Trees, and Greenspace: A Political Ecology Perspective

Urban Forests, Trees, and Greenspace: A Political Ecology Perspective
by L. Anders Sandberg (Editor), Adrina Bardekjian (Editor), Sadia Butt (Editor)

Urban forests, trees and greenspace are critical in contemporary planning and development of the city. Their study is not only a question of the growth and conservation of green spaces, but also has social, cultural and psychological dimensions. This book brings a perspective of political ecology to the complexities of urban trees and forests through three themes: human agency in urban forests and greenspace; arboreal and greenspace agency in the urban landscape; and actions and interventions in the urban forest.  Contributors include leading authorities from North America and Europe from a range of disciplines, including forestry, ecology, geography, landscape design, municipal planning, environmental policy and environmental history.

Strangers at a Funeral

Strangers at a Funeral
by Forest City Pulp

Brandon notices them at his grandpa’s funeral first: a pair of men in sunglasses who nobody seems to know. They’re not family, they're not friends, they’re just … there. No big deal, until they show up again at the next funeral. Drawn into a world of funeral selfies and burial crashers, Brandon needs to know what these strangers want from the dead.

Only problem is, nobody gives a crap except him, and his school frowns upon skipping classes to watch people get buried. His sanity can’t take many more funerals, and those bulges in the strangers’ coats probably aren’t concealing anything pleasant.

Strangers at a Funeral is a 5500 word (22 page) short story.
