Editing Quercus palustris (section)

==Distribution and habitat==
''Q. palustris'' is mainly distributed in the eastern and central United States from [[Connecticut]] in the northeast, west to eastern [[Oklahoma]] and [[Kansas]], and south to [[Georgia (U.S. state)|Georgia]].<ref>{{BONAP|ref |genus=Quercus |species=palustris}}</ref> It is also native in the extreme south of [[Ontario]], Canada.

The pin oak is also well adapted to life in Australia (where it has been introduced), and is quite widespread across the Australian continent, especially in the cooler southern States such as [[Victoria (Australia)|Victoria]] and [[New South Wales]]. It is also well adapted to life in [[South Africa]] and [[Argentina]], especially in the [[Río de la Plata]] region.

It is naturally a [[wetland]] tree,<ref name="USDA" /> confined to acidic soils, and does not tolerate [[limestone]] or sandy Florida soil, and grows at low altitudes from sea level up to {{convert|350|m|ft|0|abbr=on}}.<ref name="FNA" /><ref name="RHSLG" />

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, 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.<ref name="USDA">{{Silvics |last=McQuilkin |first=Robert A. |volume=2 |genus=Quercus |species=palustris |access-date=September 25, 2014}}</ref>
