Dedicated volunteers are the lifeblood of BFC, allowing us to send patrols into the field whenever and wherever wild buffalo are in danger.

These dedicated buffalo defenders also attend public meetings, legislative hearings, and other forums where government decisions affecting wild bison are made. Volunteers help organize rallies and protests, and some individuals have engaged in non-violent direct action to stop the slaughter and raise awareness of the cruel harassment of the buffalo. After completing our application process, selected volunteers receive training, room and board, and the use of winter gear, clothing, and equipment during their time in the field with the buffalo. Since 1997, more than 5,000 people, of all ages, backgrounds and from all around the globe, have joined BFC as volunteers: serving from one weekend to multiple full seasons.

Buffalo Field Campaign Thank You!


Seasonal Coordinators

Every winter, BFC hires a crew of committed seasonal coordinators who are responsible for key tasks arising from our most busy field season—from approximately November 15 to May 30. It is during this time of year when bison are most likely to migrate outside of Yellowstone and face harassment, shooting, and slaughter.

Each winter BFC employs seasonal coordinators to oversee our kitchen and prepare meals; to recruit and train volunteers; and to maintain vehicles and structures. A full season as a volunteer is required to be considered for one of these coordinator positions.


Year-round Coordinators

The buffalo are also fortunate to be able to count on the support of a few extraordinary people.

Stephany Seay
Media Coordinator

Stephany Seay

Born in the Outer Banks of North Carolina, and raised in Virginia, she became aware of this culture’s capacity for mindless destruction as the beaches and forests she grew up in were destroyed by so-called development. She has been an earth activist since the late 80’s, has apprenticed as a wildlife rehabilitator, and is a student of horses. Stephany started following the work of Buffalo Field Campaign in 1997. During her first visit to Yellowstone in 2003, she looked into the eyes of a wild buffalo and was never the same again. In January of 2004 she moved to Montana and has been on the front lines with BFC and the buffalo ever since. A member of Deep Green Resistance since 2015, Stephany stands in solidarity with those - human and non-human - who want to bring an end to industrial civilization and the culture that is killing our planet.  She counts among her heroes Derrick Jensen, John Trudell, and the co-founders of BFC, Mike Mease and Rosalie Little Thunder.

Stephanie Tardiff
Office Coordinator

Stephanie Cardiff

Stephanie Tardiff was born and raised in Maine. She earned a B.S. in Earth and Environmental Science with a focus in Forest Ecology from Unity College in Unity, ME. She began her work in environmentalism and community outreach while still in college and continued it as her life path after graduation, which led her to the Buffalo Field Campaign. Stephanie first volunteered at Buffalo Field Campaign during the field season of 2018. Hearing the call of the buffalo, she returned the following Summer to support education and outreach efforts. With an immense love for the buffalo, campaign mission, mountains, and outdoors she could not bring herself to leave. Humbly accepting a coordinator position for the field season of 2019, Stephanie is honored to be part of the buffalo family as the Office Coordinator, and could not think of a better place to be.
