Vegetation Management

RCD_WebAssets-Wildlife

 

Invasive weeds can be very harmful to biological diversity and destructive to natural habitats. The RCD undertakes various efforts to eradicate or control weeds where there is the potential to protect or improve natural habitats, and to restore native vegetation whenever possible.

For example, the RCD and the Midpeninsula Regional Open Space District have joined forces to eradicate slender false brome (Brachypodium sylvaticum). This aggressive perennial grass threatens the health of our local redwood forests by displacing tree seedlings and the native forest understory. It has also been observed spreading down creek corridors and can impact grazing land values, as it is undesirable forage for cattle.

Together the two districts are removing the invasive plant to protect natural areas on Thornewood and La Honda open space preserves, private lands, and local watersheds. While MROSD works to eradicate the weed on its preserves, the RCD is working with adjacent private property owners in the Woodside and Portola Valley areas where some of the best local redwood forests provide habitat for native plants and animals. Through this partnership we stand our best chance of controlling the insidious weed across approximately 200 acres before it grows to a bigger problem and threatens redwood forests throughout the state.
