A prescribed burn of bluff prairies at Pine Bend Bluffs Scientific and Natural Area was completed in April 2009. These remnants occupy the upper slopes of south-facing hills in an otherwise forested bluffland. Burning helps to reduce woody plants and to stimulate growth of the prairie species. About 30 acres were burned over 4 areas. Also completed was a large amount of exotic brush removal from around the perimeter of the prairies.
