Field Guide

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.

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.

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.

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.

Shingle oak got its name because the naturalist who discovered it noticed that French colonists in Illinois were using the wood to make roofing shingles. The leaves resemble those of laurel (bay), lacking lobes or teeth — but laurel trees don't bear acorns!

Corkwood is a rare and unusual small tree that doesn’t have a problem with having its feet wet for long periods of time, but it grows rarer as its swampy habitat is converted to cropland.

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.

In Missouri, Nuttall's oak grows naturally only in Bootheel. With its limited range, and with steady destruction of its habitat, it has become rare and imperiled within our borders.

Northern red oak is a favorite for planting in streets and parks and is one of the most widespread and commercially important of the oaks.
