I signed up for their newsletter and the first one I received was about Leave No Trace!
Some great tips in there.

Low-Impact Horse Camping
Leave No Trace

 
As we come into ride season, many of us will be setting out on some wonderful horse camping adventures! We found a very useful source of information on the principles for backcountry horse use and would like to share it with you. The excerpts below are just the tip of the iceberg in terms of what's available at www.travelingwithhorses.com. Enjoy!

Leave No Trace principles are universal for all regions of the United States. Specific information within each principle may vary from place to place, depending on the local environment and activity pursued. It is important to remember that LNT principles are guidelines, not rules. Consider your surroundings, local regulations, weather concerns, and your skill level when choosing the best way to Leave No Trace. Special considerations specific to a particular region or activity are included in more detailed LNT information.  go to the link to read more...
