Can over-reliance on moss lead to survival errors in the wild?

The Moss Direction Myth

The notion that moss grows on the north side of trees in the Northern Hemisphere has been a widely accepted myth for many years. However, this is not entirely accurate. Research has shown that moss can grow on any side of a tree, regardless of the direction, due to various environmental factors such as shade, moisture, and exposure to wind. In fact, a study in Ireland found that moss was more likely to grow on the south side of trees due to the prevailing westerly winds bringing moisture from the Atlantic Ocean.

Moss as a Navigation Aid

Moss can be used as a general indicator of dampness or moisture levels, which can be useful in certain survival situations. However, it should not be relied upon as a primary navigation aid. For example, in areas with consistent dew, moss may grow on all sides of trees, making it difficult to determine direction. In such cases, alternative methods such as using a compass, observing the position of the sun, or utilizing natural navigation features like streams and valleys should be employed. A more effective method for determining direction is to use the position of the sun during specific times of the day, such as the north-south alignment of the sun at sunrise and sunset.
