The restructuring of Forest Service research is traced from a sprawl of regional experiment stations to today's five Research Stations, the Forest Products Laboratory and more than eighty experimental forests. Budget pressure drove mergers such as the 1997 Rocky Mountain Research Station and the 2006 Northern Research Station. Officials called it a trimming of overhead, and the episode presents the network as it stood just before the current upheaval.
Counts of stations vary (five, six or seven) depending on what is included, and site totals drift from year to year. Whether the mergers merely trimmed administration or eroded research capacity is also argued.
