Date: March 3 1981Creator: Dawson, Jeffrey O.
Type: Document
Description:Letter from Jeff Dawson, Assistant Professor of Forestry at University of Illinois at Urbana-Champaign to George Ware discussing an outline of proposed research concerning the low soil oxygen tolerance (with mention of ethanol and flood tolerance) of maple and oak trees.
Enclosed with letter
An Ethanol Tree-Seedling Assay: A Potential Method to Screen Trees for Tolerance to Low Soil Oxygen Conditions Resulting from Soil Compaction and Paving. Review of current literature and proposal for two experiments to examine oxygen deficiency and ethanol tolerance in tree seedling roots. The results would be used in the creation of an tree survivability index which would be of use in flood prone areas or compacted urban and recreational sites.

ASSESSING THE BENEFITS AND COSTS OF THE URBAN FOREST (3.114680)
Date: September 1992Creator: Dwyer, John F.
Type: Article
Description:With effective planning and management, urban trees and forests will provide a wide range of important benefits to urbanites. These include a more pleasant, healthful, and comfortable environment to live, work, and play in, savings in the costs of providing a wide range of urban services, and substantial improvements in individual and community well-being. Urban forestry plans should begin with consideration of the contribution that trees and forests can make to people's needs. Planning and management efforts should focus on how the forest can best meet those needs. Past planning and management efforts have not been as effective as they might have been because planners and managers have underestimated the potential benefits that urban trees and forests can provide, and have not understood the planning and management efforts needed to provide those benefits, particularly the linkages between benefits and characteristics of the urban forest and its management.
