Shingle oak, however, can be plagued with pests such as scale insects and two-lined chestnut borer. The Morton Arboretum states that shingle oak is fairly salt tolerant and tolerant of black walnut toxicity, and despite the fact that it has a taproot, this species can be easier to transplant than some other oaks. The natural range of the shingle oak is the midwestern United States, including the Appalachian mountain region, Ohio, and the central Mississippi River valley. Shingle oaks, which grow to 50 to 60 feet tall and are found in moist, well-drained soil along streams and on hillsides, but can occasionally be found on dry sites. The acorns turn dark in color before losing their caps, although some may drop off the tree with their caps in tact. The fruit is a small, rounded acorn with a thin cap that covers a third to half of the acorn. Shingle oak tends to keep its lower dead limbs attached to the tree. The bark is dark gray and blocky, with long running ridges. The leaves turn from a dark green in the summer to yellow and brown in the fall. This species also retains its shiny, bristle-tipped leaves further into the winter than other oaks. The leaves of shingle oak are oblong and have entire leaf margins, without lobes or teeth, unlike all other Indiana oaks. This week, we take a look at the ninth and final of our featured oak varieties in Indiana, the Shingle Oak or Quercus imbricaria. The field guide helps identify common Indiana woodlot trees.Įach week, the Intro to Trees of Indiana web series will offer a sneak peek at one species from the book, paired with an ID That Tree video from Purdue Extension forester Lenny Farlee to help visualize each species as it stands in the woods. Threats to species health as well as also insight into the wood provided by the species, will be provided through additional resources as well as the Hardwoods of the Central Midwest exhibit of the Purdue Arboretum, if available. The full publication is available for download for $7 in the Purdue Extension Education Store. Nearly 70 years later, the publication has been updated through a joint effort by the Purdue Department of Forestry and Natural Resources, Indiana 4-H, and the Indiana Department of Natural Resources, and reintroduced as “An Introduction to Trees of Indiana.” Shaw was published in 1956 as a user-friendly guide to local species.
