Air Monitoring Study completed at Rancho San Antonio

The Midpeninsula Regional Open Space District is pleased to announce the completion of an air monitoring study at the Rancho San Antonio Open Space Preserve. The final study report, completed by Winegar Air Sciences, is the culmination of an extensive monitoring effort undertaken between January 2013 and June 2014. The air monitoring study was undertaken to assess air quality at Rancho San Antonio Open Space Preserve, resulting from concerns raised by members of the public and District staff related to the industrial operations at the adjacent Lehigh Southwest Cement Company.

CDFW Officials Dispatch Mountain Lion Involved in Attack

On September 10, the California Department of Fish and Wildlife (CDFW) dispatched the juvenile male mountain lion that authorities believe attacked a  6-year-old boy on Sunday, September 7.

The attack took place on the Zinfandel Trail, approximately one mile from the trailhead in the Picchetti Ranch Open Space Preserve. Our thoughts and well wishes continue to be with this courageous young boy and his family.

Wildlife experts treed the lion near the attack site, where the animal continued to display unusually aggressive behavior. In accordance with policy, CDFW staff reluctantly shot the animal.
