A dispute over the future of the Oz Natural Area in Waupaca was once again before the city council Tuesday night… and the property is once again in limbo. A local family donated the land to the city in the 1990’s, but the family says the city hasn’t used the land for its intended purpose. The city last year said they didn’t want the property and wanted to return the land back to the family Kari Esbensen is a member of the family that previously owned the property. She said, “One of the big concerns is an invasive species that has taken over in the past twenty years since the city has owned it. It’s called Japanese Barberry which harbors a heavy load of Lyme and other disease bearing ticks on it.” Esbensen says she wants to use a rotation of goats to minimize the need for chemical treatments in the natural area. But in the city, goats aren’t allowed. The council Tuesday night took up the issue again, this time voting to give Esbensen 45 days to accept their offer. If not, the offer to return the land would have to be renegotiated.
