Using wood ants nests to find your direction
The shape and direction of a wood ants nest can be used in natural navigation to find out roughly where south is!
Using a nest to find your direction
Stand with your back to the nest as if you have just walked down the shallow slope and you will be facing in a southerly direction...
How does this work? Wood ants favour a south facing, well drained location for nests. Not convinced, then read on...
Wood ants in the New Forest appear to build there nests with a southerly bias. The nests themselves are mounds of thatch constructed of pine needles, leaves and debris. In the New Forest the nests were only seen where there was a clump of coniferous trees but were often sited in nearby broadleaf woodland. Many were constructed on an existing raised (dry) boundary, mound or a tree stump.
Each nest had a steeper rear slope and a shallow front slope which appeared to face towards the south....
Each nest was photographed from the shallow front slope and each slope was measured with a phone compass screen shot which pointing in the direction of the shallow slope direction (Each screen shot is shown upright but was taken in actual direction of the slope).
