Quercus macrocarpa, commonly known as the bur oak, is a large deciduous tree native to North America. It typically grows to heights of 50 to 80 feet and features a broad, rounded crown. The tree is characterized by its thick, deeply lobed leaves and acorns, which are larger than those of many other oak species. Bur oaks thrive in a variety of soil types and are often found in prairies and open woodlands. They are known for their resilience to drought and fire, making them an important species for restoration efforts in grassland ecosystems. Their acorns provide food for wildlife, including deer and various bird species.
