Kim McFarland and Laura Julian will lead a program on the dune silver bee and the blooms they rely on.

The program will start at 1 p.m. Sunday at the Lake Earl Wildlife Area Headquarters, 2591 Old Mill Road in Crescent City.

Hosted by the Tolowa Dunes Stewards and the Redwood Parks Conservancy, McFarland will feature a slide presentation on the dune silver bee followed by a two-mile field trip to learn how they make their living at Tolowa Dunes State Park, according to a news release from the stewards. Participants will see how the bee creates a nest in the sand from which the male and female emerge in spring to mate.

In addition to talking about the flowers the bees forage from, Julian will explain how habitat restoration projects help protect the insects and promote biodiversity conservation.

McFarland studied the life history of the dune silver bee for five years as a biology graduate student at Humboldt State University. Julian is a botanist and exotic plant management specialist at Redwood National and State Parks. She’s also a member of the North Chapter of the California Native Plant Society and is actively involved in coastal dunes conservation and restoration.
