Rebecca Rubin, a 39-year-old Canadian citizen, was ordered to remain in custody during the hearing Friday in Eugene, Ore.
Trial was set for March 19.
A federal indictment accuses Rubin of being a member of cells of the Earth Liberation Front and Animal Liberation Front known as The Family. Investigators blame the group based in Eugene for 20 fires around the West that did $40 million in damage.
She turned herself in to the FBI last November at the Canadian border with Washington state. At the time, her lawyer said she wanted to get the case behind her.
