Live oak
Live oak (Quercus virginiana)

Family: Fagaceae

Common names: Cucharillo, Encino, Encino negro, Live oak, Mamecillo, Oak, Roble, Roble amarillo, Roble colorado, Roble encino, Roblecito, White oak

Distributed in: United States (North America)

Distribution overview: Black oak occurs in Ontario in Canada. In the United States, its range includes the states of Alabama, Arkansas, Connecticut, Delaware, Florida, Georgia, Indiana, Kansas, Kentucky, Louisiana, Massachusetts, Maryland, Maine, Michigan, Minnesota, Missouri, Mississippi, North Carolina, Great Smoky Mountain National Park, Iowa, Illinois, Nebraska, New Hampshire, New Jersey, New York, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Carolina, Tennessee, Texas, Virginia, Vermont, Wisconsin, and West Virginia. The tree prefers dry upland sandy and rocky ridges and slopes, as well as clay hillsides. It is sometimes found in pure stands and grows from sea level to elevations of up to 5000 feet (1524 m).

Common uses: Shipbuilding

Product sources: Live oak has little commercial value, but small quantities are available in areas where the species grows. The tree has been one of the primary sources of timber for shipbuilding, and the first publicly owned timber lands in the US were purchased in 1799 to protect the trees for that purpose.

Environment profile: Rank of relative endangerment based on number of occurences globally.

Tree size: Tree height is 0-10 m Live oak has derived its name from its evergreen foliage. The tree is medium-sized, with a short, broad and buttressed trunk and broad branches that are often covered with Spanish-moss. The tree is a popular shade tree in Southeastern United States where it matures into very large sizes

Colors: the heart isDull brown to gray brown and the sapwoodWhitish to grayish brown .The grain isIrregular, the textureFineand the lusterMedium

Natural durability: Non-durable, Perishable

Odor: No specific smell or taste

Kiln Drying Rate: Naturally dries quickly

Ease of Drying: Rapidly Green material should be protected from rapid drying. End grain should be coated and the material should be properly stickered during seasoning

Cutting Resistance: Easy to saw

Planing: Live oak is extremely difficult to work in all machining operations

Resistance to Impregnation: Resistant

Response to machining operations is generally dependent on the growth rate of the trees: fast grown southern trees are reported to produce harder material which is generally easier to work than wood from slow grown Appalachian trees.
