Also, a master plan was finalized in 2014. The ultimate goals of the plan are to build "winter-proof" year round exhibits, so that animals and people can be at the zoo all year. (The zoo is only open May-September right now). The elk, wolf, and the 2013 otter exhibit are already completed, and the eagle exhibit will be new this year.
