Facts About Forestry
How long do trees live?
Most trees don't survive their first year. However, trees can live as long as 4,000 years, but this is very rare. In Michigan, tree species longevity ranges from about 80 years to about 1,200 years (potentially). Northern white cedar is the longest living tree species in Michigan.
