Big Leaf Maple Comes By Name Honestly

The largest known Big leaf maple in the province of BC grows on the lower mainland in Vancouver's city-center Stanley Park. The big-leafed big tree is 10.70 m/35 ft in circumference, 29 m/95 ft in height, with a crown spread of 19.5 m/64 ft, and 533 AFA points. Stanley Park has champion maples galore with 5 more on the list of BC's 10 largest Big leaf maples.

That's not to say that Vancouver Island doesn't have some large maples of its own, like the epiphyte-draped tree shown above. This tree is in the same area as the more famous San Juan Spruce, the largest spruce tree in Canada. The Big leaf maple is a short distance away, dominating the center of the campground, and looking like something out of a Tolkien tale.

Big leaf maple leaves/seeds
The Big leaf maple (Acer macrophyllum), is the largest maple in Canada, and the largest deciduous tree in the coastal forest. This tree lives up to its name and produces giant leaves as large as a medium pizza.

A favourite fall activity on the coast is getting out into the forest to see who can collect the largest leaf. Not surprisingly, the winner is usually found in Vancouver.

The largest maple leaf currently on record measured 53 cm (20.86 in) wide and 52.2 cm (20.55 in) long and was discovered by Vikas Tanwar and family in Richmond, British Columbia, Canada, on 14 December 2010.
