Following an examination by Robert B. Wilson, the Portneuf division was created March 2, 1907. The Malad division, created May 28, 1906, as a part of the Bear River forest, became a part of the Pocatello in the reorganization of July 1, 1908. These national forest lands, covering, in general, the Portneuf and Marsh Creek watersheds, were merged into the Pocatello forest July 1, 1908. The Bear River forest, almost encircled by the Bear river or its tributaries, was formed May 28, 1906, and with the Logan became the Cache July 1, 1908. The Caribou forest was established January 15, 1907, the part in Bannock county lying mainly on the watersheds of the Blackfoot, Salt, and Bear rivers. Peter T. Wrensted, Clinton G. Smith, and J. F. Bruins, in turn, supervised the Pocatello, the headquarters during this time being at Pocatello. The Pocatello and Cache were joined March 1, 1914, for administrative purposes, under Mr. Smith, whose headquarters are now at Logan, Utah. Logan is the headquarters of the Cache, which has had four supervisors, John F. Squires, Mark G. Woodruff, W. W. Clark, and C. G. Smith. The Caribou has been administered by Supervisors J. T. Wedemeyer, N. E. Snell, and George G. Bentz. The headquarters is at Montpelier. The need of planting to restock the great areas of burned and insufficiently forested land in the national forests was recognized almost as soon as they were proclaimed. Particularly was this need felt as to the forests withdrawn for watershed protection, and on watersheds furnishing a domestic supply the need was most urgent. At that time a pleasing theory existed that every forest ranger should have a nursery in which to raise trees for setting out in the hills during his spare time. With this idea, the nursery on Mink Creek among others, was started. It was then realized that nursery and planting work presented specialized technical problems calling for a high degree of skill to meet successfully the adverse conditions of an arid region. Soon after the nursery was started, it was realized that success could be hoped for only by centralizing this work at favorable locations. The shipping facilities at Pocatello, together with the need of extensive planting there with a favorable site for the nursery determined the location at that place.
