Bur oak sheltered and inspired North American pioneers who settled the prairies. This bur oak or mossycup oak spotted the open spaces of the Great Plains and was noted for its thick "corky" bark that insulated the trunk and branches. The slow-growing, long-living oak could resist the fires that swept through mid-western prairies and forests. With roots that were nearly as expansive as the aboveground tree, the bur oak could withstand windstorms as well as droughts. These same pioneers found the tree to be excellent wood and waiting the necessary 20 to 30 years after planting was worth it for its shade and resistance to cold, drought and fire.

Bur oak is widely distributed throughout the Eastern United States and the Great Plains. It ranges from southern New Brunswick, central Maine, Vermont, and southern Quebec, west through Ontario to southern Manitoba, and extreme southeastern Saskatchewan, south to North Dakota, extreme southeastern Montana, northeastern Wyoming, South Dakota, central Nebraska, western Oklahoma, and southeastern Texas, then northeast to Arkansas, central Tennessee, West Virginia, Maryland, Pennsylvania, and Connecticut. It also grows in Louisiana and Alabama. Bur oaks bear seed up to an age of 400 years, older than reported for any other American oak. The minimum seed-bearing age is about 35 years, and the optimum is 75 to 150 years. The acorns are disseminated by gravity, by squirrels, and to a limited extent by water. The Bur Oak is widely planted for shade, ornament and shelterbelts.
