Quercus macrocarpa or "Bur Oak" is a large deciduous tree growing up to 30 m (100 ft), rarely 40 m (130 ft), in height, and is one of the most massive oaks with a trunk diameter of up to 3 m (10 ft); reports of taller trees occur, but have not been verified. It is one of the slowest-growing oaks, with a growth rate of 30 cm (1 ft) per year when young. A 20-year-old tree will be about 6 m (20 ft) tall. It commonly lives to be 200 to 300 years old, and may live up to 400 years.[1] The bark is a medium gray and somewhat rugged.
The leaves are 7x15 cm (3x6 in) long and 5x3 cm (2x5 in) broad, variable in shape, with a lobed margin. Most often, the basal 60% is narrower and deeply lobed, while the apical 40% is wider and has shallow lobes or large teeth. The flowers are greenish-yellow catkins, produced in the spring. The acorns are very large, having a large cup that wraps much of the way around the nut, with large overlapping scales and often a fringe at the edge of the cup.
Acorns
The acorns are the largest of any North American oak (thus the Latin species name macrocarpa or large fruit), and are an important wildlife food; American Black Bears sometimes tear off branches to get them. However, heavy nut crops are borne only every few years. In this evolutionary strategy, known as masting, the large seed crop every few years overwhelms the ability of seed predators to eat the acorns, thus ensuring the survival of some seeds. Other wildlife, such as deer and porcupine, eat the leaves, twigs and bark. Cattle are heavy browsers in some areas. The bur oak is the only known foodplant of Bucculatrix recognita caterpillars.
