Old Man’s Beard – Medicinal Lichen
Usnea is the generic and scientific name for several species of lichen in the family Parmeliaceae that are found throughout most of the world. It is commonly referred to as Old Man’s Beard and Beard Lichen, favoring to grow on trees rather than rocks as some of its lichen counterparts. Often a green color due to its content of Usnic Acid, and having stemmed the name of the color ‘usnic green’, this lichen has been used medicinally for hundreds of years and it is this content of Usnic Acid that gives it these medicinal properties.
Usnic Acid (C18H16O7) is a potent antibiotic and antifungal chemical found within most Usnea species. It was traditionally used as a bandage due to these properties. In an emergency situation, Beard lichen could be used solely to bandage and keep clean a wound. Old Man’s Beard could perhaps be used in combination with balsam fir sap (which is a topical pain killer and adhesive) to secure the lichen to the wound, keep it clean, safe from infection, and reduce pain. Usnic Acid has been found to be extremely effective against microbes like Staphylococcus, streptococcus, pathogenic fungi, as well as exhibiting antiviral, antiprotozoal, anti-mitotic, anti-inflammatory, and its own analgesic properties. These characteristics allow Old Man’s Beard to be far superior in backwoods bandaging than that of Sphagnum moss which is antimicrobial only due to its acidic pH.
Another great property of this easily identified lichen is that it is high in vitamin C, making it of good use in the prevention and treatment of scurvy. This lichen is edible and often was used as a soup thickener by early settlers to North America.
Usnea is a lichen, which is a fascinating relationship between a photosynthetic algae and a fungus with entirely different morphology, physiology, and biochemistry than that of an isolated algae or fungus and occur in some of the most extreme environments on earth. While they may be capable of living in extreme conditions, they are very sensitive to air pollution and their presence may be a good indicator of air quality in the area. This quality should be taken into consideration when attempting to locate Old Man’s Beard as it is unlikely to be found near industrial cities.

Dog Tracks vs Coyote Tracks
- You will see the coyote tracks are longer & elongated vs the dog track
- Also notice that the pads are alot closer together than on a dog
- Coyote’s front tracks are usually slightly larger than the rear tracks as opposed to a dog which are typically very close in size
- Coyote tracks are usually in a very straight line with the rear foot landing in or next to the front tracks if they are in their usual lope

Protecting your Climbing, Rescue & Rapelling Ropes
- Stepping on ropes – you never want to do this as you could press dirt, debris into the rope weakening it as well as cause an abrasion against a sharp rock beneath the rope.
- Dirt is the enemy of a long life for ropes as it winds up between the fibers and sheathing and causes wear. When you have you ropes laying on the ground try using a tarp, shirt, pack or something to isolate it from the ground is the situation allows for it
- Sun Damage – leaving a rope out in the sun can and will break down the fibers. Ropes are not made to be left out in the sun and can be damaged by UV rays, it will fade, dry and effect your rope longevity
- Make sure you know what kinds of ropes you have Static or Dynamic, and their manufacture ratings as for one to retire them based on number of falls, type of loads placed on them etc.
- Store your ropes in a cool dry place. Do not leave anything sitting on top of them
- Before and after every use of your rope you need to inspect it! Whether this takes 1 min or 10 mins your life depends on it and all ropes need to be inspected for abrasions, cuts, or any sort of damage. Go through every inch of the rope squeezing it between your fingers also trying to feel for any possible interior fiber damage
- It’s a good idea to wash your ropes once in awhile to clean out any dirt particles. Do not use any harsh degreasers or chemicals. Use luke warm water with a mild detergent like Dawn. You can do this in a bathtub, buckets, troughs etc. Dry them out in the open air out of sunlight and uncoiled, do not use any sort of heat.
