Field Guide

Its range and interesting, variable leaf shapes identify water oak. Like many species that require wet lowland forests, water oak has been declining in our state due to long-term extensive disruption of natural habitats in our Bootheel counties.

A beautiful tree, swamp white oak features bicolored leaves that are shiny, dark green above and downy white below. When a breeze sets them in motion, their wavy or lobed shapes add a calm grace to a summer's hike.

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!

Shellbark hickory is the largest of the true hickories and has the best-tasting hickory nuts in Missouri. Compared to shagbark hickory, it has larger leaves and more leaflets, plus larger nuts and orange twigs.

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.

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.

Exotic willows are available at lawn and garden centers, but there are several willow species that are native to Missouri. Most are rather humble colonizers of gravel bars, riverbanks, and lakesides. Many are important for human economic interests. All have a place in our wild ecosystems.

Willow oak's leaves are narrow, pointed, and willowlike, and like willows, this oak is associated with wet ground. In Missouri, willow oak is only found natively in our southeastern counties.

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.

White flowers clustered in round balls give buttonbush its name. It's always found near water, and thickets of buttonbush help protect lakeshores from wave action. This shrub is also planted as an ornamental.
