Travel Management

All the National Forests in California have completed an inventory of all the roads, trails, and areas used by off-highway vehicles; identifying routes from that inventory that could be added to the National Forest Transportation System without undue environmental and economic impacts and designating those routes/areas for off-highway vehicle use.

Background

The rapid expansion of OHV travel on national forests and grasslands has been impacting the natural and cultural resources of federal lands. The former Chief of the Forest Service identified unmanaged recreation - especially impacts from OHVs - as one of the key threats facing the nation's forests today.

On many forests, unmanaged OHV use has resulted in unplanned roads and trails, erosion, watershed and habitat degradation, and impacts to cultural resource sites. Although the Lassen National Forest has not experienced the same level of unmanaged OHV use as other forests, continued management is necessary to prevent additional impacts. Improved management of wheeled vehicle use on National Forest System lands would allow the Forest Service to enhance opportunities for public enjoyment of the National Forest System, including motorized and non-motorized recreation experiences.

In November 2005, the Forest Service revised its national policy governing the use of wheeled motor vehicles to develop a system of roads, trails and areas designated for motor vehicle travel to minimize or eliminate the undesirable impacts from unmanaged motor vehicle travel.

We have worked with the motorized vehicle, environmental, and other non-motorized communities to identify motor vehicle routes that might reasonably be added to the Lassen National Forest Transportation System and to develop a forest-level travel management plan that accommodates off-highway vehicle use and recreation after cross-country motorized travel is prohibited.

Implementation

Our goal is to have a transportation system that is manageable, environmentally sensitive, and economically viable. During the first phase of implementing the Travel Management Rule, we reviewed all routes on the Forest to determine which should be designated as part of the Lassen National Forest Transportation System and what vehicle use should be allowed on each. This resulted in a Motor Vehicle Use Map (MVUM) that designates which routes are open for motor vehicle use and the class of vehicle allowed. At that point, cross-country travel will be permanently banned, except by special use permit.

Route Designation Guidebook

The Region 5 Route Designation Guidebook presents the 5-step process that has guided the designation of routes on the 19 National Forests in California, including the California portions of the Humboldt-Toiyabe. A detailed description of all five steps and the timeline that shows the interrelationships among the steps make up the main portion of the Guidebook.
