The "Big Tree" is a species of oak called Quercus virginiana. These oak trees can be found from Texas to Florida with their range extending northward to Virginia. The common name for the Quercus virginiana is the live oak but includes the names southern live oak and the Texas live oak too. Live oak growth rate and size vary by location.
It is distinguished from Quercus virginiana (southern live oak) most easily by the acorns, which are slightly larger and with a more pointed apex. It is also a smaller tree, not exceeding 1 metre (40 inches) in trunk diameter – compared to 2.5 m (75 in) in diameter in southern live oak – with more erect branching and a less wide crown. [5]
Live oak will survive well on both dry sites and in wet areas, effectively handling short duration flooding if water is moving and drainage is good. Good soil drainage is a key resource component for sustained live oak growth. The usual precipitation range is 650–1,650 millimetres (25–65 in) of water per year, preferably in spring and summer.
According to the Live Oak Society the oldest southern live oak is believed to be the Seven Sisters Oak located in Mandeville, Louisiana with an estimated age of 500–1,000 years. [3] The southern live oak is the official state tree of Georgia. The Seal of Texas includes a live oak branch. A small grove of live oaks on a prairie is known as a ...

It is one of the slowest-growing oaks, with a growth rate of 30 centimetres (12 in) per year when young. However, one source states that a well-established tree can grow up to 51 cm (20 in) per year. [4] [unreliable source?] A 20-year-old tree will be about 18 m (60 ft) tall if grown in full sun.
The mean annual increment (MAI) or mean annual growth refers to the average growth per year a tree or stand of trees has exhibited/experienced up to a specified age. For example, a 20-year-old tree that has a stem volume of 0.2 m 3 has an MAI of 0.01 m 3 /year.
The Mexican blue oak is common at elevations of 1,200 to 1,800 m (4,000–6,000 ft).It is often found on thin sandy soils in semi-arid regions and is the dominant species in lower open oak woodland where it grows in association with Arizona white oak (Quercus arizonica) and Emory oak (Quercus emoryi).
