Quick Answer
Moss growth often indicates the direction of shade, which can be useful for navigation in forested areas, as it suggests the direction of a tree's canopy.
Understanding Moss Growth Patterns
Moss is a non-vascular plant that grows in dense, green clumps. It thrives in humid environments with low light levels, making it a reliable indicator of shade. In a forest, moss growth often occurs on the north or east side of a tree, where sunlight is less intense.
Locating the Direction of Shade
To use moss growth for navigation, look for areas with dense, green moss. If you find a large area of moss growing on the ground, it’s likely to be on the north or east side of a nearby tree. Measure the angle of the sun to estimate the direction of the tree’s canopy. For example, in the Northern Hemisphere, the sun is at a 90-degree angle to the horizon at noon in the summer, and at a 20-degree angle in the winter. Use this information to estimate the direction of the tree’s canopy.
Interpreting Moss Growth for Navigation
When using moss growth for navigation, consider the following factors: the type of tree, the climate, and the time of year. In general, moss grows more densely on the north side of trees in temperate climates. However, in tropical or subtropical climates, moss growth may be more uniform. In areas with dense tree cover, moss growth may be more difficult to interpret. To increase the accuracy of your navigation, combine moss growth patterns with other indicators, such as the direction of bird flight or the position of the sun.
