The Leave No Trace program teaches and develops practical conservation techniques designed to minimize the "impact" of visitors on the wilderness environment. "Impact" refers to changes visitors create in the backcountry, such as trampling of fragile vegetation or pollution of water sources. The term may also refer to social impacts--behavior that diminishes the wilderness experience of other visitors.

These principles are a guide to minimizing the impact of your backcountry visits to America's arid regions. This booklet discusses the rationale behind each principle to assist the user in selecting the most appropriate techniques for the local environment. Before traveling into the backcountry, we recommend that you check with local officials of the Forest Service, Park Service, Fish and Wildlife Service, Bureau of Land Management or other managing agency for advice and regulations specific to the area you will be traveling in. First and foremost, it is important to carefully review and follow all agency regulations and recommendations; these materials support and complement agency guidelines.

Minimizing our impact on the backcountry depends more on attitude and awareness than on rules and regulations. Leave No Trace camping practices must be flexible and tempered by judgment and experience. Consider all of the variables of each place including the soil, vegetation, wildlife, moisture level, the amount and type of use the area receives, as well as the overall effect of prior use. Use these observations to determine which recommended practices to apply. Minimize your effects on the land and on other visitors, while enjoying your visit as well. Effective minimum-impact practices are incorporated into the national Leave No Trace education program as the following Leave No Trace Principles:

Plan Ahead and Prepare Unnecessary impact in backcountry areas can be avoided by carefully preparing for your trip. For example, if you do not have adequate equipment for grazing restraints, you maybe forced to put horses on short picket, perhaps even utilizing live trees as the picket anchor. The potential for overgrazing and girdling live trees is extremely high. Impacts resulting from being unprepared may seem minor, but they are not uncommon and over time result in long-lasting damage.

Expectations Determine the goals and expectations of your trip. Consider your group size, number of horses needed, route length, possible activities, the age and abilities of other group members and their expectations. This will help you choose the best times and places to travel in order to meet your goals.

Knowledge of the area Many backcountry visitors do not live near the areas they wish to visit. Inquire with local land management personnel for information on such considerations as access, weather conditions, snowpack, available feed, high-use areas and wildlife considerations (such as presence of black or grizzly bears). There may be closures and prohibitions that you should be aware of. You may not be able to camp where you had planned. Some areas are closed to grazing and most areas restrict the number of horses a party can use.

Get out your maps and go over the route. Consider the river crossings, alternate campsites, mountain passes and fishing opportunities. Familiarize yourself with other trails and roadheads that you could use in case of an emergency.

In popular areas you can assume you will be able to find existing highly impacted campsites to use. Conversely, in remote or seldom visited areas, you must be willing to take extra time and use a variety of techniques in order to Leave No Trace of your having camped there. With good information you will be better prepared for your trip, have a more enjoyable experience and be better prepared to minimize your impacts.

Meal planning and food preparation Plan your meals carefully. Repackage food into reusable containers or plastic bags. This will reduce the amount of potential trash or litter you bring into the backcountry. Carefully planned rations also reduce waste from leftovers and minimize the amount of extra food carried.

Equipment Make an equipment list. Select equipment and horse gear that allows you to minimize signs of your stay. Light-weight gear, such as compact stoves and nylon tents and sleeping gear, can help reduce the number of horses required to support your trip, thus reducing impact to trails and meadows. Examine the gear itself. Many amenities can simply be left at home. Taking only what you need will make setting up and breaking down camp go much more quickly. A simple camp makes it easier to Leave No Trace.

The horses Before entering the backcountry you should consider the following points concerning the horses themselves:

• Take only the minimum number of animals necessary.
• Take only animals which are fit, calm, experienced. For example, a mare in heat or an unbroken colt would be inappropriate.
• Practice at home the techniques to be used in the backcountry before heading out. The roadhead is not an ideal place for an animal to learn about breechings, clinking and clanging pannier loads or windblown mantis. Accustom your horses to the type of restraints you will be using. Prior experience with backpackers, llamas and other odd-looking wilderness users may save a major wreck and the impact it can cause.
