PORTLAND, Maine (AP) — Maine's largest city is telling its residents to stop vandalizing traps that are designed to help move turtles to a pond.

The city's official Twitter account says Thursday that traps at Evergreen Cemetery are part of a project to transport turtles from the cemetery back to Capisic (CAP'-is-ick) Pond.

The city says some of the traps have been vandalized, presumably because people thought the traps were designed to harm animals. The city assures residents the traps "are a good thing."

The city didn't have a number of how many turtle traps had been vandalized as of Thursday.

Evergreen Cemetery is the second-largest public space in Portland and it's popular with nature lovers, in part because of its winding walking paths, woods and wetlands.
