Forest Service Road Maintenance Series: Forest Roads and the Environment
An introduction to maintenance of low volume roads. Emphasis is on the interaction of the road and the environment. Stresses that proper maintenance of the roadway actually helps keep the ecosystem in balance. It is possible for roads and nature to coexist, however it takes effort and planning. Lessons such as: Disturb the soil only when absolutely necessary. And, when it is necessary, use a light touch are applicable beyond the nation's forests, to other low volume, unpaved roads, that serve multiple needs (recreation and commercial) and that run through otherwise natural environment.'
Originally a public domain film from the National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

Forest roads or forest tracks are roads or tracks intended to carry motorised vehicles or horse-drawn wagons being used mainly or exclusively for forestry purposes, such as conservation or logging. Forest roads may be open to ramblers or mountain bikers depending on local rules...
Forest roads may be tarmacked, gravelled or metalled (using hard core) and often have restrictions on use. In many regions the establishment of forest roads is not only subject to approval under forest management law, but also conservation law.[1]
In riparian forest and other especially important conservation areas, forest roads and tracks are generally signed as being out of bounds and/or closed off with barriers.
In mountainous regions the situation is more complex. On the one hand, forest roads on steep mountainsides must be wider than on the plains in order to enable vehicles to safely negotiate hairpin bends. On the other hand, the widening of old tracks runs the risk of heavier erosion or landslides...
Forest roads may be subdivided into various classes according to their capacity. For example, in Germany, the key of topographic maps distinguishes between are metalled roadways (Befestigte Fahrwegen), roadways (Fahrwegen), forest tracks (Waldwegen) and footpaths (Fußwegen), the latter not being suitable for forest vehicles...
