Jamestown S’Klallam Tribe has cultivated ecosystems on the North Olympic Peninsula since time immemorial. In honor of the tribe and their efforts of reestablishing a native plant prairie and traditional harvesting practices behind the Dungeness River Audubon Center, the center is hosting “Prairies and People of the Olympic Peninsula,” a speaker series that looks deeply at the ecology of prairies, the tribe’s historic connection with prairies, and their plans for working prairies in the future.

Events are free and set for 6 p.m. at the Dungeness River Audubon Center, 2151 W Hendrickson Road.

The schedule includes:

• March 5, “Prairies: Cultural Ecosystems” with Mackenzie Grinnell and Lisa Barrell, Jamestown S’Klallam Tribe’s Traditional Foods and Culture Program

• March 12, with Dave Peters, U.S. Forest Service Prairie Ecologist

• March 19, “Archaeology of Sequim Prairie,” with David Brownell, Jamestown S’Klallam Tribe Tribal Historic Preservation Officer.
