Turning California's Desert into Green Belt
Protecting the Global Environment!

【California】
In the southwestern United States, there are vast desert areas such as the Mojave Desert and the Sonoran Desert.
This area also includes major cities such as LosAngeles and Las Vegas.
If this area can be greened, it could be utilized as a major economic resource.

Greening method

Use cover plates with pot holes. Cover plates are laid in the desert to cover the sand surface.
Fill the pot holes with soil and seed with Texas Frogfruit.

Texas Frogfruit

Lippia nodiflora of Verbenaceae family. The stems are long and slender, branching at the base, creeping low on the ground surface, lowering the roots from the nodes, often in clumps.
It is widely distributed in tropical and subtropical regions of the world and has been established as a naturalized plant in North America.
With its low growth rate, its ability to crawl and spread across the ground surface, and its fast land coverage and low maintenance, it is expected to be a ground cover plant as an alternative to turf. Desert greening using Texas Frogfruit is also being studied.

For the time being, it will be provided by Trust Co., Ltd.
Local production will be also possible in the future.

Contribution to the Global Environment

Cover plates and Texas Frogfruits cover the surface of the desert to prevent the evaporation of groundwater.
It prevents rain disasters caused by torrential rains and prevents ground subsidence.
It will solve such degradation of the global environment.
