How do we protect and preserve some of the last remaining urban wilderness areas in Southern California? That’s the objective of the recently formed Urbanwild Network, which has its roots in the unnecessary destruction of a pristine oak woodland in Arcadia.

Two representatives of this new organization, Christle Balvin and Mary Barrie, will make a presentation on the lost Arcadia woodland and show other rural sites that are threatened by L.A. County’s need for additional sediment dumps.

All are welcome. Beverages, plates and utensils will be provided. Bring a dish serving 6-8 people.

Gather Saturday, Sept. 10, at 5:30 pm; dinner at 6 p.m.; program at 7 p.m., at Eaton Canyon Nature Center, 1750 North Altadena Drive in Pasadena.

Directions: From the 210 Fwy in Pasadena, take Altadena Drive north 1.5 miles to the intersection with New York Drive. About 500 feet after the intersection, turn right at the sign into the park.
