Volunteers are needed to clean up litter in the Corrales Bosque Preserve on Saturday, October 16. The Corrales Bosque Advisory Commission will lead a trash removal effort at the Siphon Road entrance at the extreme north end of the preserve. Volunteers should bring gloves, but collection bags will be provided. That clean-up will start at 8:30 a.m., said chairperson Joan Hashimoto.
