National forest:

Originally, forest reserves, established by Presidential proclamation mostly between 1891 and 1909. Today, the boundaries of the 155 national forests cannot be modified without congressional authorization, although many (especially eastern) national forests are combined for easier administration. The 117 administrative units, commonly referred to as national forests, are managed by the Forest Service for multiple use and sustained yield of renewable resources, as determined in forest plans.
