Barbed Goatgrass Control Research
Creekside staff has been working diligently to control Barbed Goatgrass (Aegilops triuncialis) in occupied Bay Checkerspot habitat on Coyote Ridge. This annual grass occupies areas where important forbs (like host and nectar plants) may grow. Notably, BGG seems to form denser stands thus deteriorating Checkerspot habitat. We present the following findings (see PDF below) on…
