The Ohio State University Extension Why Trees Matter Signature Program is a multi-disciplinary program focusing on the ecological, economic and social benefits of trees. This program is tailored for Ohio and Great Lakes area citizens, community officials and foresters, and the green industry (an over $10 billion industry in Ohio with over 100,000 employees).

Our partners include OSU researchers, Extension educators and specialists, Master Gardener and Certified Naturalist volunteers, state agencies including the Ohio Department of Natural Resources Division of Forestry, green industry companies, from nurseryman to landscapers to arborists and tree care companies such as Ohio’s own Davey Tree Expert Company, the largest tree care company in the world, and partners from universities and the United States Forest Service throughout the United States.


The Why Trees Matter mission statement is “To develop science-based educational resources to document and demonstrate the ecological, economic and social benefits of trees”.

Example of this include:

Ecological audits of street trees in a number of Ohio communities and other locations (urban forestry)

Youth programs such as the Tree-mendous Day program partnership of Harold Schnell Elementary School in West Carrollton Ohio (video) Results of the Ohio Street Tree Evaluation Program, which builds on

40 years of survivability and tree growth data in major Ohio communities (OSTEP)

Monthly Why Trees Matter articles in the Buckeye, the official publication of the Ohio Nursery landscape Association Power Point presentations of topics on tree identification, selection, and results of our annual Why Trees Matter Forums held each October. (Power Points)
