Field Guide

Easily Missouri’s most valuable tree, the black walnut provides the finest wood in the world, as well as delicious nuts. Both are in high demand and thus form an important part of Missouri’s economy.

A native to much of eastern North America, eastern white pine has been widely introduced in Missouri and sometimes reproduces on its own.

Post oak has long been favored for fence posts and was valued by American pioneers. It has distinctive cross- or ghost-shaped leaves. It grows in rocky upland woodlands and in flatwoods on broad ridges.

Overcup oak is fairly easy to identify. The acorns are almost completely covered by their knobby cups. The leaves have long, narrow lobes and wide sinuses. In Missouri, it grows naturally only in wet forests along the Mississippi and Meramec rivers.

Blackjack oak is common in dry upland woods, especially ones that have been badly burned. It can grow on the poorest soils. It is rugged but not worth much as lumber. It's one of the first trees to be used as fuel.

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.

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.
