Traditional Seed Sowing Worker - Original Landscape Greening Method

Introduce native herbaceous plants produced domestically to achieve slope greening.

This is a greening method that rapidly green slopes by spraying domestic native herbaceous seeds, achieving full greening while considering regional ecosystems and biodiversity. It enables speedy greening comparable to that of foreign grasses and can create landscapes reminiscent of Japan's original scenery (grasslands). Currently, most native seeds used for slope greening are imported foreign species referred to as "foreign native species." These foreign native species have been pointed out to pose risks such as genetic disruption due to hybridization with indigenous species that originally grow in the country, as well as ecological disruption caused by the unintended mixing of foreign species' seeds. This has been explicitly stated as "not to be used" in the action plan of the 2023-2030 National Biodiversity Strategy. Domestic native herbaceous seeds are stored and managed at the RS Center (seed-specific storage facility) by applying the early germination power testing method and seed storage technology that our company has cultivated for native woody seeds. When shipping seeds to the site, we deliver products that are accurately weighed and packaged based on seed mixture design for each construction unit.
