How To Identify Plants At The SRP: Plant Distribution
- A fundamental law of biology: the number of species is proportional to roughly the third root of area. This is true for animals and plants.
- It makes sense! More area allows more species to exist. The number of species cannot increase as fast as the area, since some species will be found in the larger area.
- Thus the rule of thumb: if you consider an area ten times larger, you will find twice as many species.
