The River Birch: A Familiar Streamside Favorite
The river birch is a familiar favorite of many nature lovers. It’s not only an attractive tree, but it’s also a valuable wildlife resource (birds and rodents feed heavily on the tree’s seed). For that matter, the tree’s bark is one of the most celebrated sources of tinder among hikers and campers.
A quick-growing riparian pioneer, the river birch often grows alongside the other usual lowland suspects, including ironwoods (Carpinus caroliniana), red maples (Acer rubrum), sweet gums (Liquidambar styraciflua) and alders (Alnus spp.).
River Birch Identification: Tips & Tricks
The river birch rarely presents identification problems. It’s leaning, often-multi-trunked growth habit and peeling bark are often visible from afar, and its habitat preference provides another clue in natural locations. This is actually a pretty easy species to identify in any season.
But the leaves are also distinctive and allow for a quick and easy ID in the spring, summer and fall. Strongly triangular and “double-toothed” (the teeth have teeth), these leaves are pretty easy to recognize.
