PHOENIX (AP) — The Phoenix Parks and Recreation advisory committee won't allow any holiday trees to be left on Camelback Mountain this December.

KPHO-TV reports (http://bit.ly/2ruW7ZW ) the committee voted Monday to stick with the city's "leave no trace policy" that states no one can leave anything behind in parks or on trails -- including seasonal decorative items.

Last December, a group calling itself "Camelback Santa" carried a 15-foot (4.57 meters) Christmas tree up Camelback Mountain the day after Thanksgiving. But 24 hours later, park rangers removed the tree because of the policy.

Camelback Santa was hoping to be exempt from the policy.

The city cited a number of issues, including litter around the tree. City officials say park rangers were forced to maintain the tree, which is not in their list of responsibilities.
