This stock photo shows a forest of tall, straight Douglas-fir trees, Pseudotsuga menziesii, in the Cathedral Grove Rainforest, MacMillan Provincial Park, Vancouver Island, British Columbia, Canada. Cathedral Grove is a rare and endangered remnant of an ancient Douglas fir ecosystem on Vancouver Island in British Columbia (BC), Canada. The biggest trees in the Grove are about 800 years old and measure 75 m (250 ft) in height and 9 m (29 ft) in circumference (right). They are the survivors of a forest fire that ravaged the area some 350 years ago and the even more devastating invasion by Europeans who colonized Vancouver Island from 1849.
