Another planned deer cull in Ann Arbor continues to generate controversy. Last winter, 63 animals were killed in an effort to thin the herd in the city. This year, city council has authorized the killing of up to 100 more animals and the sterilization of up to 60 female deer. That plan was approved on a 9-2 vote. David Fair’s guest on this week’s edition of WEMU’s "Issues of the Environment" is Mayor Christopher Taylor, who voted against the cull.
