A female wildland firefighter has been tapped by the Trump administration to steady the U.S. Forest Service as it reels from allegations of sexual misconduct and struggles to change its male-dominated culture. Vickie Christensen was appointed interim chief of the 35,000-employee agency late Thursday. The move came roughly 24 hours after former Chief Tony Tooke abruptly retired following revelations of an investigation into alleged relationships with subordinates. Christiansen has been with the Forest Service for seven years and became a deputy chief in 2016. Before joining the federal government she'd worked in forestry for 30 years at the state level, in Arizona and Washington.
