Differences
The tree is native to North America, not the British Isles. In British contexts, it would be referred to as an American tree species. The term 'bur' (referring to the acorn) is standard in American botanical English; British speakers might simply use 'bur oak' as the species name or note it as an 'American oak'.
Connotations
In the US/Canada: connotes a native, hardy, large prairie tree. In the UK: primarily a botanical/gardening term with no cultural connotations.
Frequency
Common term in North American forestry, ecology, and horticulture. Very rare in general British English except among botanists, gardeners, or arborists discussing non-native species.
