Discover Nature: American Sycamore

Dec 23, 2020

Now that most leaves have fallen from Missouri’s trees, look for the smooth, white limbs of a giant rising over streams and river banks: Discover Nature this week with the American Sycamore (Platanus occidentalis). 

A living sentinel of our streams, sycamores provide year-round food and shelter for river wildlife. 

Migrating songbirds, woodpeckers, wood ducks, and raccoons nest in its hollow cavities. Great blue herons and bald eagles build their bulky nests in its branches. And its roots shelter game fish and other aquatic wildlife, while stabilizing soil against heavy rain and erosive floods. 

Even its broad leaves, which shade and cool water temperatures in summer, become food for insects and feed nutrients back to the soil when they fall. 

An integral part of streamside habitats, sycamores grow larger than any other deciduous tree in the United States. 

Early explorers reported sycamores with trunks as large as 47-feet in circumference! For comparison, Missouri’s current champion sycamore measures approximately 19-feet in circumference (measured at four feet above the ground).
