The overall Forest Service budget has indeed been increasing, but it's nearly all going to wildfire fighting. I recently wrote about the state of forest road funding and went in depth on this here: https://ephemeral.cx/2024/09/losing-access-to-the-cascades
Overall, in 1995 16% of the Forest Service budget was dedicated to wildfires. By 2015 it was 52% and by 2025 it’s projected to be upwards of 67%. Without large amounts of additional funding it is virtually guaranteed that the Forest Service’s budget will continue to be siphoned away by firefighting needs.
