Creating a Miyawaki forest is about setting up a real forest ecosystem. Over the years, flowering plants, herbs, mosses, and mushrooms will appear under the cover of trees. The forest provide shelters for many animals: birds, insects, small mammals. A Dutch study showed that animal biodiversity of a Miyawaki forest is on average 18 times higher than that of a conventional forest. Depending on the species, we can observe from 2 to 162 times more.
