2025 marked the ninth season of the Champinefu Series, which was founded by the Marys Peak Group of the Sierra Club and the Cultural Resources Department of the Confederated Tribes of the Grand Ronde. The purpose of these talks is to inform the general public about local Indigenous lands, rivers, and people. During the past nine years, there have been 27 unique programs featured through this series, some in person and others via webinar.

The 2025 series was launched at OSU in October with an in-person program titled “The Future of Indigenous Foods in the Kalapuya Ilihi”. Members of the Confederated Tribes of the Grand Ronde who work directly with developing programs related to Indigenous foods were featured. 

The November talk was a webinar entitled “Indigenous Placekeeping through Tea.” It featured David Harrelson from the Cultural Resources Department of the Confederated Tribes of the Grand Ronde. He is experimenting with the processes related to Indigenous teas. 

The December webinar was a dialogue between OSU’s Dr. Molly Carney and David Harrelson as they focused on the cultural relevance of the tarweed plant and the importance of regenerating tarweed ecology in the Willamette Valley. That talk was called "Kalapuya Placekeeping through Tarweed". 

The Corvallis-Benton County Public Library's Champinefu Webinar Series YouTube playlist contains videos from this program dating back to 2021.

Co-sponsors of the series are the Confederated Tribes of the Grand Ronde, the Corvallis Sustainability Coalition, the Spring Creek Project, the Corvallis-Benton County Public Library, the OSU School of Language, Culture & Society, and the Marys Peak Group. Champinefu Series programs and presenters are all chosen by the Cultural Resources Department of the Confederated Tribes of the Grand Ronde.
