We are hosting a broom-busting pizza party and raffle on Horse Hill with The Alto Bowl Horseowners Association. Over the past 20+ years we have pushed back invasive French and Scotch broom on this Open Space preserve. Now we need your help to make a final push into the broom frontier on the western part of the preserve. The work site is located approximately ¼-mile up, toward the top of the hill. We’ll pull broom and sow native grass seed. Some members of association will talk about their horses living on the preserve. Participants will get a chance to meet the horses up close. The work requires considerable strength and stamina. Lunch served around Noon.

It is possible for volunteers as young as 5 years old to join if teamed with a parent or guardian. Dress in layers you can get dirty, wear sturdy shoes, and bring water. Please bring gloves if you have them. Snacks, lunch and extra water will be provided.
In the event of heavy rain and/or high winds call (415) 473-3778 to find out about event status. In the event of cancellation, program will be rescheduled.
