Field Guide

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.

Scarlet oak is a common tree of the Missouri Ozarks. Today it occupies much the same area that shortleaf pine used to dominate before it was extensively cut prior to the 1920s.

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.

Eastern hop hornbeam is named for its fruits, which are clusters of flattened, papery, scalelike sacs arranged in an overlapping pattern, like scales on a pinecone — resembling the hops that beer is made from.

The dwarf chestnut oak, though only 3–10 feet tall and the shortest of Missouri's oaks, can nevertheless produce abundant acorns that are relished by several types of birds and mammals.

Chinkapin oak is fairly easy to identify because of its distinctively toothed leaves. Look for it growing in rocky soils derived from limestone or dolomite on bluffs and in upland woods, and in floodplain forests and lower slopes along streams.

Black oak grows throughout Missouri, in upland woods, on glades, and along borders of woods and fields. It and scarlet oak were the primary colonizers of Ozark pinelands when the native pines were cleared in the early 1900s.

Shumard oak is worth knowing: it can rise to 100 feet in height and gain a trunk diameter of 5 feet, with wide-spreading, muscular boughs.
