Topline:

Oysterpalooza is here! Orange County’s first — and free! — oyster festival is this Saturday in Huntington Beach.

Why oysters? Oysters filter and improve water quality … and can help prevent coastal erosion. Yet native species have been nearly wiped out since the Gold Rush era sparked overharvesting and coastal development. The nonprofit Orange County Coastkeeper has been working to restore oysterbeds along the OC coast for more than a decade.

What to expect: Oysterpalooza will feature speakers highlighting the group’s restoration efforts, as well as local food, beer and sustainable product vendors. Of course, there will be oyster tasting too!
