A memorial service for environmentalist Jan Vandersloot is slated for 1 p.m. Dec. 6 at Castaways Park, 700 Dover Drive, Newport Beach.
Vandersloot died suddenly at his Newport Beach home Nov. 4. He was 64.
A dermatologist with a practice in Huntington Beach, Vandersloot was one of the founding members of the Bolsa Chica Land Trust, a group dedicated to preserving the Bolsa Chica Wetlands in Huntington Beach.
He also helped found the Ocean Outfall group, which pushed for the Orange County Sanitation District to clean up wastewater being pumped offshore.
