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.


The Michigan Arbor Day Program is transitioning to be a program of the Michigan Department of Natural Resources.  Stay tuned for information in early 2023!



  National Tree Benefits Calculator

Curious just how much value the trees on your property provide to you and the environment? You can enter little bit about your tree and this website will estimate the amount of carbon dioxide and pollution it removes from the air, the energy it conserves, what the tree adds to your property value as well as the amount of stormwater it can help mitigate. It's quick and easy!


Michigan Forests

Michigan is a richly forested state, and has 20.3 million acres of forest land. The Upper Peninsula has the most forest land and the Southern Lower Peninsula has the least, but the amount of forest land in Southern Michigan is growing! Facts from the Michigan Forests 2014 report

  • Sugar maple/beech/yellow birch forest type accounts for 19 percent of the State’s forest land
  • Aspen type accounts for about 12 percent
  • White oak/red oak/hickory 7 percent.
  • Balsam fir, red maple, and sugar maple are the three most common species by number of trees
  • Every ash species, paper birch, yellow birch, and American beech are experiencing a decline in growth and numbers.
  • Non native species such as Emerald Ash Borer, and Beech bark disease are decimating our Ash and Beech trees.
  • Michigan’s wood products and paper industries directly employ 34,951 workers with an output of approximatley $10.2 billion annually.


The Value of the Urban Forest

Why 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.
