Douglas Fir Tree Size Comparison
As shown at the World Forestry Center in Portland, Oregon, Douglas Fir can grow to immensely large trees.
Old growth Douglas Fir can reach heights of well over 300 feet tall and over 12 feet across at the base.
The immense volume of added fiber from 240 to 635 years in age is a pretty clear illustration of just how
much these incredible trees can grow when left to mature. The life expectancy of Douglas Fir when left on its own is 500 to 1000 years.
Natural occurrences such as fire, wind, and disease can cut short the life of these truly magnificent trees.
