Every fence takes space, takes land takes nature, takes biodiversity.
Each pole normally measures 2,7' x 2,7' or 7 cm x 7 cm
Each pole of a fence takes approximately 19 sq ft or 49cm2 of land and biodiversity
Simpson's Diversity Index is used to calculate a measure of diversity, taking into account the number of something as well as its abundance.
The proportion (n/N) of individuals of one particular species found (n) divided by the total number of individuals found (N), Σ is still the sum of the calculations, and s is the number of species.
*This is a rough estimate taking into account that all species can't be counted due to their size and quantity.
The Simpson Calculation index ranges from 1 to 0.
Meaning that this quick estimation is a reflection of the vast amount of biodiversity located with just a quick counting of species.
In a small fenced piece of land (50mts x 25mts or 164" x 164") where each pole is located every 2 meters or 6".
A total area of 1715cm2 or 104 sq ft will be taken by only poles.
If all the world's fences can cover the world over 200 times. Think how much land and biodiversity is taken just by fences themselves.
