Field Guide

Found throughout Missouri and in all kinds of habitats, the white oak is one of our most attractive, long-lived, and stately shade trees. Learn to recognize it by its light gray bark, rounded-lobed leaves, and distinctive acorns.

Bur oaks can live for hundreds of years and become giants; many have legendary or historic status. As with most oak species, it can be identified by leaf shape.

Many Missouri trees are quite useful, and shagbark hickory is a great example. Its wood makes excellent, slow-burning charcoal, its nuts are edible, and its wood is used for many implements. Wildlife from moths to squirrels to bats appreciate shagbarks, too!

Black hickory's nut, like that of the pignut hickory, is awfully hard to crack. Because rural Ozarkers noticed their hogs had no trouble extracting the sweet kernels, both species came to be called "pignut hickories."

Of the several hickories in Missouri, bitternut hickory is the only one with long, bright yellow buds. Its common name refers to the bitter taste of the nut — but the flavor doesn't put off squirrels, mice, and deer!

The pecan, a type of hickory, is one of Missouri’s favorite nut trees. Originally pecan had a fairly limited, southern distribution, but today it is found in and out of cultivation nearly statewide, owing to the popularity of the nuts.

Missouri is rich with hickory trees. Mockernut hickory stands out from the rest for its hard wood, thick-shelled fruit enclosing relatively small kernels, large and light-colored terminal buds, and tight, never shaggy, bark.

The white, smooth-looking limbs of sycamore rise over countless streams and river banks, as well as over sidewalks and city streets. The leaves, which somewhat resemble those of maples, can reach remarkably large sizes.

Named for the cottony fluffs of hairs attached to its tiny seeds, cottonwood thrives in moist lowlands near streams and rivers. It is Missouri’s fastest-growing native tree but pays for that distinction by being relatively short-lived.
