quercus havardii

Quercus havardii (common names include shinnery oak, shin oak and Havard oak) is a deciduous, low-growing, thicket-forming shrub that occupies some 2 to 3 million hectares in the southern Great Plains of North America. Clones may reach hundreds to thousands of years old, although aboveground stems typically live only 11 to 15 years. Shinnery oak stems are usually 1–2 m tall and codominate the plant community with mid- and tall-grasses which are usually taller than the oaks.
