Which animals might live in this tree?
An idea to try
Measure 9 metres of string or yarn together, then lay it in a circle on the floor: that is about the distance around the park’s biggest Douglas fir.

A little more to discover
In MacMillan Provincial Park on Vancouver Island, Cathedral Grove protects an old-growth Douglas fir forest. Some trees are more than 800 years old, and the largest measures more than 9 metres around. Forester H.R. MacMillan donated the land in 1944, and the park was created three years later. On the coast, Douglas firs can grow up to 100 metres tall.
BC Parks asks visitors to stay on marked trails, to protect the forest, and to stay off the trails on windy days, because old trees and branches can fall without warning. Ask your child what a tree might have seen in 800 years.
