[ARCHIVED] Giving Natives A Chance

FOR IMMEDIATE RELEASE

Contra Costa County Flood Control Held Successful Event 

to Restore Native Plants in Local Creeks 

December 14, 2018, Concord, CA – The Contra Costa County Flood Control and Water Conservation District together with The Restoration Trust had 50 volunteers including County Supervisor Karen Mitchoff’s staff, City of Concord Mayor Carlyn Obringer and her staff, County Public Works Department staff, Contra Costa Resource Conservation District, Pleasant Hill Boy Scout Troop 239, Northgate High School students, Clayton Valley Charter High School students, and many other community members at the 6th annual Giving Natives a Chance planting event last Saturday, December 8.

This event focused on returning native plants to local creeks and flood control channels. Efforts have been focused on the Clayton Valley Drain off Solano Way in Concord, which drains to the Walnut Creek Channel, Carquinez Strait, and then to the Pacific Ocean. This year’s work included planting 5,000 native grass plugs on the south creek bank, pulling invasive weeds, and removing a pick up truck’s load of garbage out of the creek. Prior to 2013 and the restoration work, the site had less than 5% native cover. Native cover is now at 45% and is likely to continue to increase as the native vegetation grows and expands.
IMG_8535The creek was planted with Santa Barbara sedge, Baltic rush, and creeping wild rye. Each species has different environmental needs and has beneficial effects on separate parts of the channel. These species are native grasses or sedges that provide erosion control, fire suppression, and are compatible with flood control objectives. These species remove as much as 500,000 gC/acre a year or about ½ ton of Carbon per acre per year.
