Welcome to Michigan Arbor Day Alliance!

The Michigan Arbor Day Alliance (MADA) is a coalition of organizations and agencies dedicated to the promotion and celebration of Arbor Day throughout Michigan. Our dedication comes from our belief in the importance of trees and their role in community health and well-being.

MADA is a program of the Eaton Conservation District in Charlotte, MI.


The Value of the Urban Forest

 Why are trees so importanWhy are urban forests so important to our economy and human health? Nationally, urban forests are estimated to contain about 3.8 billion trees, with a structural asset value of $2.4 trillion, which doesn’t include other ecosystem service benefits.

Urban trees in the lower 48 states store 770 million tons of carbon, valued at $14.3 billion,  and remove approximately 784,000 tons of air pollution annually, with a value of $3.8 billion.

Studies have shown that every $1 invested in urban trees results in $2 to $4 in benefits, including lowered energy costs, reduced stormwater flows, improved aesthetics, higher air quality and reduced carbon dioxide concentrations. Trees act as natural pollution filters, removing polluted particulate matter from water and absorbing nutrients like nitrogen, phosphorus and potassium, which are all common byproducts of human activities. A single front-yard tree can intercept 760 gallons of rainwater in its crown, reducing runoff and flooding on your property.
