Survival Myth Busted: Finding Directions by Tree Moss

Survival Myth Busted: Finding Directions by Tree Moss

One of the pervasive folk legends about finding directions  in the wilderness or woods, is that moss grows on a certain side of a tree or rock. Just find your way by observing where the moss is,  according to this theory, and you won’t get lost.

According to this traditional old “wisdom” the moss is thickest on the north side of a tree in the northern hemisphere. In the southern hemisphere, the moss is thickest on the south side.

Subsequently, this survival tip will help you to find your way in a forest. Here’s one opinion about that: finding directions with moss

But the newspaper guy in me had to ask: What direction does the moss point? Is there a difference in the location of the forest and the way the moss points? What are the variations? Why? Where did this legend come from?

The basis for this directional moss idea may have come from general information about moss. Moss produces spores instead of seeds, and it needs a damp  environment to reproduce.  Moss spores don’t survive in dry areas.

The sun shines from the south in the northern hemisphere, so a tree’s north side is generally more shaded and damp.  It stands to reason that there would be more moss on the damp  – the north – side

The moss myth never got far with me. In the dense, deciduous forests of Mississippi where I used to hunt and ramble, I could never find any pattern for the moss. In any dense, thick forest – where the sun doesn’t penetrate as far – it seems like you’ll see mosses on all sides of the trees. In some of standing water swamp areas where I used to wader-hunt for ducks, the moss was everywhere. It sometimes varied because of the fluctuating water levels!

As for rocks, well, mosses will grow on almost anything if conditions are favorable.  I suppose you might find more

moss on the north side of rocks in an open area, but in a shaded forest, chances are good that the rocks will be completely covered.

There are apparently so many variables about where and when moss grows in a forest  that a firm rule can’t be established.

In July, 2010, I was at Camp Makualla Boy Scout camp in the Cascades with some of the scouts from Troop 18 in Bend. There was a lull in the action, so I took my compass and camera and went walking. The idea was to check out this directional moss theory. (And, I love to ramble through the woods, and never need much of an excuse! )

I couldn’t find a consistent pattern anywhere. In one area, the moss grew on the west side of the trees, because there had been some timbering going on that let in more sunlight. A short distance away, the trees and underbrush were so dense that moss was everywhere.

One of my requirements for a wilderness survival tip is consistency. The skill or technique must work every time, because there is no room for error when it comes to survival.

To me, the bottom line on the moss directional theory is this: Moss grows everywhere in the wilderness. There is not enough consistency, that I could find, to lend creditability to this “survival tip.”

Don’t depend on finding your way, based on directions gotten from the moss on trees. This idea is NOT something to promote or rely on.

Subsequently, I dub direction finding by observing  moss growth a myth. And I proclaim that myth busted!

    Just because somebody wrote about something doesn’t make it true. Take all survival advice – including this – with a grain of salt.

    I have found the moss on the tree to be completely bogus and I hate that people have been told this for decades and believe it. Kind of a urban myth in a way.
