Natural restoration greening using domestic indigenous species: slope afforestation method.
Natural restoration greening method using domestic native woody plant seeds aimed at 'biodiversity conservation,' 'environmental conservation,' 'slope disaster prevention,' and 'creation of CO2 absorption sources.'
This is a natural restoration greening method that uses domestic native woody seeds to spray and create forests on slopes. By adding a seed supply device to the conventional vegetation substrate spraying construction plant, the "two-layer spraying system" allows for the mixing of seeds only in the top 2 cm of the growth substrate, enabling effective use of seeds and cost reduction. In recent years, there has been a growing interest in slope greening that does not use foreign species, such as grasses from the Poaceae family or foreign native species, in light of laws regarding invasive species. The "Road Earthworks - Cutting Works and Slope Stabilization Guidelines (2009 Edition)" also lists 24 species of native woody plants as the main plants used for seeding work. To use domestic native species, which have a larger variation in germination rates compared to foreign species, for slope greening, it is necessary to use seeds of clearly defined quality. The slope afforestation method uses domestically produced native seeds that have been quality tested using an early germination test method and supplies seeds packed in quality-preserving material-filled measuring bags (Remedy Seeds) from its unique seed storage and shipping facility (RS Center).

basic information
【Features】 ○ We use a natural restoration greening method that considers biodiversity with native species from domestic sources and does not use invasive species (species of concern). ○ A two-layer spraying system that reduces costs and effectively utilizes valuable native woody seeds will be the standard specification. ○ High-quality seed in measured bags containing quality-preserving materials (Remedy Seeds) will be supplied from dedicated storage facilities (RS Center). ○ The seeds used will be certified for quality by the Japan Tree Seed Research Institute through early germination tests. ○ Based on years of experience and construction results, we propose seed mixtures suitable for the region. ○ We achieve early natural restoration with a material mixture that has high erosion resistance and is suitable for the germination and growth of woody seeds. ○ Seeds collected locally or regionally can be stored at the RS Center and can also be used in greening construction. ● For more details, please contact us or refer to the catalog.
