Miyawaki’s MethodMiyawaki’s method firstly discovered and applied by Akira Miyawaki who found out the importance of conservation through restoration by using Miyawaki’s technique.
It is first emerge when he realizes that Japan’s degraded land was covered by invasive species and not the original species thus lowering the diversity of species on the forest area in Japan. As he experimented with the method, there have been numerous successful project that have been resulted from the Miyawaki’s method. From the results, he also implement the method into other types of forests by collaborating with international country such as Malaysia, Amazon, China and India. ImplementationThe method were implemented by restoring the degraded forests from seeds that are originated from the forests itself. The method will be done by restoring the degraded soils so it will provide the new seedlings that will be planted on the site. Therefore, as this method is very effective to the regeneration of forests, it has been applied and included in the project of restoration done in UMS Campus. The project was called Reforestation & Tropical Vegetation Conservation Center Establishment in UMS Campus. The implementation of the method was done starting by selecting native dipterocarps seedlings to cover the entire area on the Bukit UMS.
The Miyawaki’s method was implemented during the fourth phase of the restoration project which is includes in the Planting Work align with the enrichment planting process. The Miyawaki’s Method early process were actually done by preparing plant site to plant seedlings. Then, the seedlings was let to grow on its own and with a three years of maintenance. After three years, just after the germination the seeds was selectively collect from the natural forest. Then, the seedlings were let to germinate in the propagation beds and nutured.
It is then transferred into the seedling bed under shaded roof with 60 % shaded rate continued with another 1 to 2 months of nurturing the seedlings with 30 to 40 % shaded rate. This is to make sure that the seedlings are getting its optimum source from the sunlight. After that, the seedlings were planted into existing natural forest area so that it will adapted on natural environmental condition necessary for its adaptable characteristics. This is to make sure that when the time to plant the seedlings for a restoration project, it will adaptable to the environment and growth successfully. On the project of restoration that was done on the UMS, the seedlings was supplied by INFAPRO, Yayasan Sabah which is selectively chosen. The seedlings was planted on planting beds using Miyawaki’s method with some modification done in reforestation plots. On the site, the seedlings was planted near each other in 1 metre square plots.
Firstly, three seedlings was planted in 1 plots, however the number is increased to 4 seedlings due to limited costs. Although the planting techniques will create competitiveness among seedlings to grow, the aims is to let the strongest seedlings to growth through natural process. Characteristics and condition the of siteThe criteria for a site to be restored is the site is already degraded and full of invasive growing species. In addition, based on the site chosen in the project done in UMS, the site is the only forest land area in the city of Kota Kinabalu. Thus, as it only specific in this area of UMS, therefore preserving it with native species are more valuable then letting it full growth with full of invasive species. As Dipterocarps species are valuable and originated in Borneo, the diversity of this species can be increase and conserved for the benefits of the future. There are several criteria considered for a site or land to be restored (F.Orsi, D.
Geneletti, A. C. Newton, 2011) : (Relatable criteria)l Accessibilityl Degradation levelsl Disturbancel Forest characteristicl Land usesl Natural regeneration potentiall Size of areal Tehcnical knowledgel Water availability, etc.Why is it need to be restored?It is important to restore the area, as it can increase and conserve the diversity of important tropical species rather than wasting the supply of soil nutrients for invasive species. The diversity of the area can be a good advantage for future research as it can provide genetic sources. The main purpose of the project is to build a rehabilitation area that can provide nature interpretation for environmental education.
Thus, this will provides place for researchers and students to do their research and project that related to environment, biology, science and etc. The result and importance of restoration especially by using Miyawaki’s methodAs the result, Miyawaki’s method has enable the tropical seedlings to grow naturally and inhabited the rehabilitation site around UMS Peak. By observing around the area to UMS Peak, the native species performed well in the project. Based on the research done by Dr.
Elia, it is mentioned that the use of large seedlings have increased the survival of the seedlings, as it compete with other vegetation. Thus, provide high survival rates between all species and sites. Although the site condition near UMS Peak are located in open area. The seedlings have survived and grown well due to its quality and adaptability. On the first place, Dipterocarps species are generally known to grown in shaded area with enough moisture as a source for the germination and establishment process.
