Wilderness and Backcountry Site Restoration Guide

Acknowledgments

Planning a well-crafted restoration project in wilderness is like putting together a complicated jigsaw puzzle-after all the pieces from several puzzles have been jumbled together and several of the pieces have been lost in the couch or sucked up in the vacuum cleaner. Writing this guide has been an exercise in furnishing all the puzzle pieces for a successful restoration project-or at least enough of them that any holes left in the puzzle won't create a big problem.

With a deep sense of gratitude, the authors wish to thank others who assisted in the preparation or review of this guide.

Introduction

For the past two decades, resource managers have attempted to address the impacts caused by human actions in backcountry and wilderness areas. In some wildernesses, wilderness study areas, and national parks, these impacts are quite extensive: large areas denuded of vegetation, compacted soils, braided trails, and tree roots exposed after horses have been tied to trees. For many reasons, including water quality, soil stability, and esthetics, managers would like to prevent further impacts and help the existing impacts heal.

Wilderness management plans have addressed impacts by establishing desired conditions, indicators, and standards. Indicators such as vegetation loss, tree roots exposed, and the number of social trails are monitored to keep track of changes to the resource. Standards set limits on the amount of change that will be accepted before management action. In some wilderness areas, standards were not being met when the management plan was signed. In such situations, actions must be taken to prevent further resource degradation and to bring the resource back into compliance with standards. A number of actions are possible, one of which is physical restoration of the site. Although restoration is not necessarily the best choice in many situations, restoration can be very effective if it is done properly.

Managers across the Nation have had varying degrees of success with restoration. Some areas, such as the North Cascades National Park in Washington, have had successful restoration programs for years. The North Cascades program includes a greenhouse operation where plants are grown from seed or from cuttings that are collected on the site, carried into the backcountry, and planted. Other areas with fewer resources and less precipitation have not been as successful.

There is no textbook answer that guarantees success in backcountry site restoration. Much restoration knowledge is learned by trial and error. Many, many different techniques have been tried in one area or another, although information about these techniques may not have been passed along. This guide has been developed to facilitate information exchange. It is a compilation of the best information available from researchers and practitioners.

Purpose of This Guide

This guide was developed to provide managers with information that could help them decide whether to attempt restoration and, if so, how to go about it appropriately in wilderness. This guide will help managers share information and exchange ideas.This guide is:

  • Focused exclusively on restoration of small-scale impacts caused by human actions, such as recreation use or removal of administrative or special provisional structures (structures exempted under "Special Provisions" in section 4(d) of the Wilderness Act). Use of the word "site" in this publication refers to any number of small-scale disturbances—not necessarily a campsite.

  • Based on the assumption that projects are in wilderness or backcountry settings (figure 1).

  • Based primarily on examples from the Western United States—from the Rocky Mountains westward (figure 2). Many of the techniques and procedures apply to any environment.

This guide is not:

  • A guide to large-scale ecological restoration. Human-caused disturbances, such as mining and grazing, have occurred in wilderness at a landscape scale. Large-scale ecosystem restoration is a complex topic. Philosophical questions could be raised about such large-scale restoration in wilderness, where it might be regarded as a form of manipulation or "trammeling." Many large-scale applications need to be designed to meet regulations and engineering specifications that this guide does not address.

  • A guide on fire suppression rehabilitation or burned area emergency rehabilitation (BAER).

  • A guide to motorized tools or mechanized transportation, although these methods may be mentioned.

Special Wilderness Considerations

The Wilderness Act of 1964 set aside lands in the United States "to secure for the American people of present and future generations the benefits of an enduring resource of wilderness" to be "administered for the use and enjoyment of the American people in such a manner as will leave them [the lands] unimpaired for future use and enjoyment as wilderness…."

Congress further defined wilderness "as an area where the earth and its community of life are untrammeled by man, where man himself is a visitor who does not remain." Wilderness "is protected and managed so as to preserve its natural conditions and which (1) generally appears to have affected primarily by the forces of nature, with the imprint of man's work substantially unnoticeable…."

The Wilderness Act also includes special provisions allowing certain uses primarily because they existed before lands were designated as wilderness. These uses include grazing and mining.

The Wilderness Act's mandate can pose interesting challenges for a wilderness manager who needs to manage for recreation, mining, grazing, and other activities, while keeping "man's work substantially unnoticeable." In some cases, impacts that occurred before lands became wilderness threaten the integrity of the wilderness. Impacts may include vegetation and soil loss, unnecessary structures, and invasive plant populations. Where these impacts exist, managers feel an obligation to do something. Frequently, restoration is the solution that comes to mind.

Agency policies require that wilderness be managed to allow natural ecological processes to operate freely. Management actions should be the minimum necessary to preserve and protect wilderness. The Wilderness Act specifies that wilderness be untrammeled by man. It's appropriate to ask questions such as:

  • Is active revegetation of a disturbed site too manipulative?

  • Is this action the minimum necessary?

  • Do our actions interrupt the natural ecological processes?

Before a wilderness manager begins planning for a restoration project in wilderness, it is critical for the manager to think about the answers to these questions. Restoration does not consist simply of scarifying a site, sticking plants in the ground, and going away for the summer.

Restoration is a manipulative action that deserves a great deal of thought and planning, both to minimize the impacts to wilderness and to increase the likelihood of success. In many situations, the solution is simply to eliminate use at the site and allow the natural process of healing to occur. It is important to question your actions continually to be confident that they are the minimum necessary.

Goals of This Guide

  • To provide guidance on developing a plan that thoroughly addresses the question of whether site restoration is the best management action and, if so, how to develop a site-specific restoration plan.

  • To provide the latest information on site-specific restoration techniques, including site preparation, soil amendments, planting, mulching, and so forth.

  • To explore the various methods of plant propagation both on and off the site.

  • To inform managers of the documentation and monitoring required before undertaking a project and for ongoing progress reports.

Target Audiences

The target audiences for this guide include anyone who plans or implements site restoration in backcountry or wilderness areas or who would like to do so, including wilderness rangers, wilderness managers, resource specialists, recreation planners, or trail crew members. Anyone who reviews restoration plans or advises anyone who implements the plans would benefit from reading this guide.

Nomenclature

Not only common names, but also the scientific names of many plant species have been changing in recent years. An attempt has been made to determine current usage, to determine which of the species discussed in this book has a new name, and to determine whether any name used is authoritative.

One of the easiest sources for help in sorting out common and scientific names is the U.S. Department of Agriculture (USDA) PLANTS database on the Internet at http://plants.usda.gov, although this database may not be up to date for all species.
