Here are a few 'Rent-a-Goat' companies.

Many, including West Coast Grazing, clearly state that their goats can tolerate poisonous plants, including "digesting poison hemlock, poison ivy, poison oak, and other noxious weeds that are otherwise dangerous for most animals."

Star Creek Land Stewards can accommodate areas from 10 to 1,000 acres, so Pescadero Canyon will surely be covered. And there's plenty of room for their trailer in the grass off 2nd Avenue (so as not to block fire access).

Goats-R-Us' herd can be deployed to clear hillsides, roadsides, utility corridors, and wild land-urban interface zones, consuming grasses, brush, and overgrown shrubs before they become a fire hazard...

Chasing Goat Grazing has some cute goats as well.

If you search on Google for "goat grazing companies Northern California", the list goes on...
