Atmospheric Carbon Dioxide and Carbon Storage in Urban Wood Products by Sam Sherrill
This presentation is based on two research projects conducted by Sam Sherrill and Steve Bratkovich in 2011 and 2018. In 2011 Dovetail Partners conducted a study on the potential for carbon sequestration in three urban hardwood products: landscape mulch, biomass for fuel, and solid wood products. An Excel model was developed that focused specifically on tons of sequestered carbon dioxide equivalent of solid hardwood products from urban forests in the United States. Estimates for a 30-year period were developed for several situations based on assumptions about variations in carbon and wood harvest. The minimum estimate from the 2011 study was approximately 124 million tons of CO2e that could be sequestered nationally in urban hardwood products over a 30 year period. Beginning in 2016, a follow-up study reconstructed the national model developed in the previous investigation to convert tons of sequestered CO2e into board feet. In addition, to making the results more user-friendly to urban wood industries, architects, and other interested parties, two products were selected, and sequestered CO2e was estimated.

The Urban Wood Toolkit
The Urban Wood Toolkit was designed to be used by municipal foresters, city managers, community volunteers, or students who are interested in finding the highest and best use for removed urban and community trees. Using wood from urban and community tree care residues is an effective way to reduce municipal forestry costs and waste, promote stronger linkages with the forest products industry, and produce new economic opportunities.
The Urban Wood Toolkit helps users to prioritize the most important goals and objectives for their community’s wood, recognize the types of information or resources necessary to advance, and identify the types of services that you may need from additional partners.
The Urban Wood Toolkit was developed in 2018 by our partners in Michigan, Verdant Stewardship and Spalted Banjo Consulting, through support from the Michigan Department of Natural Resources, the Sustainable Resources Alliance, and the USDA Forest Service Northeastern Area.
Harvesting Urban Trees with Modern Logging Equipment
With financial assistance from a U.S.Forest Service Wood Education Resource Center grant, SRI worked with a unique group of entities to demonstrate and analyze the effectiveness of mechanized cut-to-length equipment to remove and process urban trees. The City of Oak Creek agreed to be part of the project in order to assist them in addressing one of the most substantial Emerald Ash Borer (EAB) outbreaks in Wisconsin. The week-long demonstration determined the cost effectiveness of using this type of equipment and to determine if enough material would be harvested to economically market sawlogs, pulpwood, and chips.
In addition to the City of Oak Creek, other public entities involved included the Wisconsin Department of Natural Resources – Division of Forestry; Wisconsin Department of Agriculture, Trade, and Consumer Protection; and the US Forest Service Forest Products Lab. From the private sector, Timber Resources, the Sustainable Resources Institute, Inc., Northeast Forestry Services, and Vermeer Wisconsin provided a variety of services. Wisconsin Master Logger Certified Northeast Forestry Services was contracted to do the felling, processing, and forwarding of all designated trees with their harvester and forwarder.
