Quick Answer
Some foragers believe in moss myths for survival because they think that moss grows more densely on the north side of trees and rocks. This supposed north-south pattern is thought to help foragers determine their direction in the wilderness.
The Moss Myths Debunked
Foragers often rely on moss to estimate direction, but this method is based on incorrect assumptions. The growth of moss does not follow a predictable pattern, and it can grow on any surface that receives adequate moisture and shade. In fact, a study found that moss growth on trees can be influenced by factors such as tree species, age, and exposure to wind and sun.
The Problem with Moss as a Direction Indicator
One of the main issues with relying on moss as a direction indicator is that it can be easily confused with other types of vegetation. For example, lichen and ferns can also grow on trees and rocks, making it difficult to distinguish between them and moss. Additionally, moss growth can be affected by local microclimates, which can cause it to grow in patterns that are unrelated to the direction of the sun or wind.
Better Methods for Estimating Direction
Instead of relying on moss, foragers can use more reliable methods to estimate direction, such as using a compass, observing the position of the sun, or identifying landmarks. For example, during the day, the sun rises in the east and sets in the west, making it a reliable indicator of direction. At night, the stars can also be used to estimate direction, with the North Star (Polaris) being a reliable guide in the northern hemisphere.
