Oak south of Catt Hall.
The bur oak is native
to the eastern US, extending into south central US. It is the most widely
distributed native oak in Iowa and the most abundant tree in the
forests of the western and north central parts of the state. Due to its
thick bark, the bur oak was able to withstand prairie fires and could
grow on the edges of the plains, making it a forest fringe species. The
bur oak is a considerably important timber tree in the US. Although
it makes an excellent shade tree, the bur oak is seldom planted in
urban areas, as young trees are difficult to transplant, slow to grow and
the mature tree has an extensive root system.
