Acer pensylvanicum, known as the striped maple, moosewood, moose maple or goosefoot maple, is a small North American species of maple. The striped maple is a sequential hermaphrodite, meaning that it can change its sex throughout its lifetime.
Description
The striped maple is a small deciduous tree growing to Шаблон:Convert tall, with a trunk up to Шаблон:Convert in diameter.[1] The shape of the tree is broadly columnar, with a short, forked trunk that divides into arching branches which create an uneven, flat-topped crown.
The young bark is striped with green and white, and when a little older, brown.[1]
The leaves are broad and soft, Шаблон:Convert long and Шаблон:Convert broad, with three shallow forward-pointing lobes.[1]
The fruit is a samara; the seeds are about Шаблон:Convert long and Шаблон:Convert broad, with a wing angle of 145° and a conspicuously veined pedicel.[1][2][3]
The bloom period for Acer pensylvanicum is around late spring.[4]
The spelling pensylvanicum is the one originally used by Linnaeus.
Small, finger-diameter sections of branches can be used to make whistles due to the ability to lightly bruise the bark, slip it off the wood, carve the whistle hollow and airflow channel into the wood, and slip the tube of bark back on.
Distribution
The natural range of the striped maple extends from Nova Scotia and the Gaspé Peninsula of Quebec, west to southern Ontario, Michigan, and Saskatchewan; south to northeastern Ohio, Pennsylvania, and New Jersey, and along the Appalachian Mountains as far south as northern Georgia.[5][6]
Ecology
Moosewood is an understory tree of cool, moist forests, often preferring slopes. It is among the most shade-tolerant of deciduous trees, capable of germinating and persisting for years as a small understory shrub, then growing rapidly to its full height when a gap opens up. However, it does not grow high enough to become a canopy tree, and once the gap above it closes through succession, it responds by flowering and fruiting profusely, and to some degree spreading by vegetative reproduction.[7][8]
Mammals such as moose, deer, beavers, and rabbits eat the bark, particularly during the winter.[9]
