More than a quarter of firefighting positions at the United States Forest Service (USFS) remain vacant, according to internal data reviewed by the Guardian, creating staffing shortages as extreme conditions fuel dozens of blazes across the US. The data paints a dangerously different picture than the one offered by Tom Schultz, the chief of the USFS, who has repeatedly assured lawmakers and the public that the agency is fully prepared for the onslaught in fire activity expected through this year. It’s already been busy. So far this year there have been more than 41,000 wildfires – an amount nearly 31% higher than the ten-year average. “In terms of firefighting capacity we are there,” Schultz said during a Senate committee hearing on 10 July, claiming the USFS had hit 99% of hiring goals. He repeated the claim multiple times.
