Intermediate and suppressed trees in such stands usually die within a few years of being overtopped. Single pin oaks in mixed stands usually are dominants. Pin oak is considered a subclimax species. It persists on heavy, wet soils because it produces an abundance of acorns which, if released, grow faster on these sites than most of its competitors. 97: 53: 543: 72: 555: 700:
most poorly drained sites that may be covered with standing water through much of the growing season. However, they do grow extensively on poorly drained upland "pin oak flats" on the glacial till plains of southwestern Ohio, southern Illinois and Indiana, and northern Missouri. The level topography and presence of a claypan in the soil of these areas cause these sites to be excessively wet in winter and spring.

suitable locations, causing the tree to shed leaves during the growing season and rot from the top down. Mature pin oaks are often too big to treat and this nutrient deficiency on alkaline soil may eventually kill them. The drooping lower branches can also be a problem, interfering with access for traffic and pedestrians.

Although pin oak is very tolerant of dormant-season flooding, it is much less tolerant of growing-season flooding. Trees may be injured or killed by intermittent growing-season flooding over several successive years. The trees can usually survive one growing season of continuous flooding, but will be

It grows primarily on level or nearly level, poorly drained, alluvial floodplain and river-bottom soils with high clay content. They are usually found on sites that flood intermittently during the dormant season, but do not ordinarily flood during the growing season. They do not grow on the lowest,

In its native range, pin oak is the most commonly used landscaping oak along with northern red oak due to its ease of transplant, relatively fast growth, and pollution tolerance. However, as it is naturally adapted to moist, acidic soils, it may develop a condition known as iron chlorosis on less

Like all oaks, flowering and leaf-out occur in late spring when all frost danger has passed. The flowers are monoecious catkins which, being self-incompatible, require the presence of another oak for pollination. Any species in the red oak group can serve as a pollinator, but in pin oak's natural

In its natural environment pin oak is a relatively short-lived, fast-growing pioneer or riparian species with a lifespan of approximately 120 years against many oaks which can live several centuries. Despite this there are many examples of pin oak that exceed this lifespan. It develops a shallow,

Large areas of almost pure pin oak occur on the "pin oak flats" of the upland glacial till plains or in the bottom lands of the lower Ohio and central Mississippi River valleys. Associated species in this forest type include red maple ( 516:. Young trees under 6 m (20 ft) are often covered with leaves year-round, though the leaves die in the fall, remaining attached to the shoots until the new leaves appear in the spring. As with many other oak species, dead pin oak branches stay on the tree for many years. 864:
killed by continuous flooding over 2 or 3 consecutive years. Pin oak is rated as "intermediately tolerant" to growing-season flooding. Also, since the bark of pin oak is relatively thin, the species is especially susceptible to damage by fire and decay associated with fire wounds.

Young trees have a straight, columnar trunk with smooth bark and a pyramidal canopy. 884:. However, it can be distinguished by its distinctive dead branches on the lower trunk ("pins"), and its uniquely shaped crown. The sinuses on pin oak leaves are also deeply cut, often covering just as much area as the leaf itself. 802:–American elm forests in the bottom lands along the Ohio, Wabash, Mississippi, and Missouri Rivers. A variant of this type, silver maple–American elm–pin oak–sweetgum, is found along major streams in southern Illinois and Indiana. 578: 566: 665:

The common name "pin oak" is possibly due to the many small, slender twigs, but may also be from the historical use of the hard wood for pins in wooden building construction.
