Ecologists suspect it helps by reducing the abundance of adjacent plant species and giving the endangered grass more space to thrive.

[2] Initially, the Point Reyes National Seashore staff worked with ranchers to bring back prescribed grazing with the help of electric fencing around the area where the Sonoma alopecurus population occurs.

Unstable soils, high winds, and cattle disturbance caused the fence to fall over, minimizing the effectiveness of grazing efforts.

In 2020, the park applied for and received a regional NPS block grant to finish the final 2,000 feet of fence construction.

Completed that November, the fence allows Sonoma alopecurus habitat to be efficiently, intensively grazed during the winter when the grass is not flowering or setting seed.
