River Birch is a little known in Quebec. This tree is native to Eastern United States and Midwest.
Like many birches, it has a rather peculiar bark. It comes off in white, gray and orange papery strips.
This tree grows naturally in damp or wet environments such as river banks. It's therefore appropriate to use the River Birch in order to protect or stabilize the soil against the erosion in the riparian zone.
The hardiness of this birch seems somewhat nebulous. In the literature, the information is often contradictory... Note that nice specimens grow in Van-Den Hende Botanical Garden, Quebec. This can be a good indicator of the hardiness of the River Birch.
Although in Quebec, no real test has been done in this direction, River Birch would not be very well adapted to urban conditions. It would be sensitive to pollution among others...
