(Radio Iowa) – Iowa’s largest zoo is launching what’s described as a “transformative” project, one of the most comprehensive expansion and renovation efforts in the facility’s 60-year history. Blank Park Zoo spokesman Alex Payne says ground is being broken in Des Moines this week on the first of two big additions, expanding the lion habitat. It will be three times bigger than the current area, offering guests three different viewing experiences, each featuring floor-to-ceiling glass for unobstructed and accessible views of the lion pride. Tigers will also move into the new habitat, and Payne says the goal is to be a successful breeding facility for both lions and tigers. The 18-million dollar plan also calls for the zoo to break ground later this year on what’s to be called the “Wild Iowa” habitat, featuring native Iowa creatures like otters, bobcats and bald eagles.
