Striped Maple

Description:

It is a small deciduous tree growing to 5-10 m tall, with a trunk up to 20 cm diameter. The young bark is striped with green and white, and when a little older, brown. The leaves are broad and soft, 8-15 cm long and 6-12 cm broad, with three shallow forward-pointing lobes.

Habitat:

Moosewood is an understory tree of cool, moist forests. It prefers slopes. It is among the most shade-tolerant of deciduous trees. It can germinate and persist for years as a small understory shrub, growing rapidly to its full height when a gap opens up. It does not ever become a canopy tree, however, and once the gap above it is closed, it responds by flowering profusely, and to some degree by vegetative reproduction.

Notes:

I spotted this hiking in Algonquin provincial park.
