Waldo’s recent blog about trees made us wonder how many different kinds of trees grow on our campus. The answer: 409. There are 143 evergreen species, 241 deciduous species and 25 species of fruit trees. The oldest tree is a Douglas fir that’s likely more than 100 years old, said Jeff Hughes, grounds and sustainability manager. The oldest Douglas fir on record grows on Vancouver Island and is estimated to be 1,300-1,400 years old. Douglas firs can grow up to 200 feet tall. Like most evergreens, they grow faster when young and then slow way down with age. Our tallest is about 80 feet tall – about half grown.
