Sertoma Park is home to an experimental Miyawaki Forest. Miyawaki Forests are designed based on old growth forests. In these forests, seeds are dropped and grow densely together, quickly competing for available light. A Miyawaki Forest simulates that by planting 3-5 small, native tree and shrub saplings every square yard. By planting the trees and shrubs so close together, it causes them to grow tall quickly to compete for sunlight. This quick growth leads to taller trees. A Miyawaki Forest will grow 10 times as fast as a forest planted using conventional methods.
Though only 10% of the plants will survive, below ground, the roots become closely intwined, supporting each other and providing a biologically dense and active soil. The netting of the roots also provides for a solid base structure, reducing the fall risk of a tall, fast-growing tree.
This method has been practiced around the world with much success. It has been used as a successful method of restoring rainforest habitat, creating urban forests, and providing protection from tsunamis and easily flooded areas.
