Quercus macrocarpa, or bur oak, is a large oak native to central and eastern North America. Its distinctive acorns have deep, fringed cups.

Quercus: Quercus is a genus of deciduous and evergreen trees and shrubs commonly known as oaks. Bur oak is one species in this large, diverse genus.
Urban forestry: Urban forestry is the planning and care of trees and wooded spaces in towns and cities. Bur oak tolerates drought and urban conditions, making it a long-lived shade-tree choice.
Oldest bur oak in Iowa: The oldest bur oak in Iowa is a state-record tree recognized for its exceptional age and size. This celebrated individual illustrates how large and long-lived the species can become.
Fire ecology: Fire ecology studies how fire interacts with organisms and ecosystems. Repeated low-intensity fires helped maintain habitats where bur oak thrives.
Fagaceae: Fagaceae is the botanical family of flowering plants that includes oaks, beeches, and chestnuts. This family places bur oak among trees with related flowers and fruits.
Wildlife habitat: Wildlife habitat is the combination of resources and environmental conditions that supports a species’ survival and reproduction. Its acorns feed wildlife, while its canopy and cavities provide shelter.
Bur oak savanna restoration: Bur oak savanna restoration is the recovery of open oak grasslands through measures such as controlled burning and tree removal. Restoration projects recreate the open conditions in which bur oak historically flourished.
White oak group: The white oak group is a lineage of oaks whose acorns mature in one growing season. Bur oak belongs to this group, unlike red oaks with two-year acorn development.
Deciduous tree: A deciduous tree sheds its leaves seasonally, usually in response to cold or dry conditions. Bur oak loses its leaves each autumn across much of its range.
Oak savanna: An oak savanna is a grassland ecosystem with scattered oak trees and an open canopy. Bur oak often dominates savannas where fire and open conditions limit other trees.
