A small herd of metal cows “graze” at the entrance to the Watson Industrial Park on the corner of Merrill and Hellman avenues, east of Chino Airport. The statues, featuring four cows, a bull, a calf and a dog, honor the dairying industry in the Chino Valley. In its heyday in the 1980s, the Agriculture Preserve in Chino and Ontario had the largest concentration of dairies in the nation. The Preserve, which offered tax incentives to farmers who kept their land in agriculture, broke in the early 2000s as dairy farmers sold their land and moved to Central California and out of state. The Preserve community in south Chino gets its name from that agriculture zone.
