University of Montana President Royce Engstrom says changes must be made to the Foresters’ Ball if the nearly century-old tradition is to continue.

About 140 students were kicked out of the dance this month for being intoxicated and unruly.

In a Tuesday letter to College of Forestry and Conservation Dean James Burchfield, Engstrom laid out the changes he wants. They include making the event earlier, eliminating venues that encourage inappropriate behavior, having a more manageable attendance size and planning to keep drunk people from entering.

Engstrom also says the dance must be family friendly for at least part of the time and it must be designed to be educational as opposed to a party.

Engstrom set an April 15 deadline to submit a plan for a redesigned ball.
