* Paper Birch (Betula papyrifera): This is the most likely candidate, as it's known for its distinctive white, papery bark that peels easily in thin sheets.
* Gray Birch (Betula populifolia): Also known as "white birch," this species has smooth, grayish-white bark that peels in thin, papery sheets.
* River Birch (Betula nigra): This birch has distinctive reddish-brown bark that peels in thin, papery layers.
To narrow down the species, consider these additional factors:
* Location: Where did you see the tree or shrub? Different species have different ranges.
* Leaf Shape: Paper birch leaves are broadly oval, while gray birch leaves are triangular and river birch leaves are more elongated.
* Bark Color: Paper birch has white bark, gray birch has grayish-white bark, and river birch has reddish-brown bark.
If you can provide more details, I may be able to help you identify the specific species.
