As the wild land is going to extremes, it is impossible to be recoverd by the general species.
So we have to use the plants which can survive even the poorest environment to recover the wild land.
In that point, it is noticeable that application of sedum which is the most representative of all the ground cover plants.
Because the sedum grows out very well and it is the most prolific of all plants, it can cover with the largest area.(215 times)
It also can survive the extreme change of the temperature and very dry climate.
If we use this specificity of the sedum well, we will be able to strengthen the natural recovery.
So it´s not impossible to get back the destroyed eco-system.
Making grasslands by transplanting sedum will create the organic deposits and it can be the foundation of the food chain.
It also can be the most important basic step of the recovering eco-system.
Recovering eco-system by the food chain will be advanced with these 4 steps :
1st step: Creation of the organic deposits by sedum
--Formation the soil condition that is basic for the plants growth.
2nd step: The natural growth of the grass and inhabitation of the insects on the organic deposits.
3rd step: Inhabitation of winged animals that feed insects and
the natural growth of the perennial by the ejection of the winged animals.
4th step: Formation of the food chain in the order of a plant-eating animal and
a flesh-eating animal.
And desertification that extreme form of the wild land is spreading rapidly all over the world, even though we try very hard.
So we suggest the seawater irrigation project as the innovative plan to combat desertification and moreover to use desert practically. This system is very epochal that can restore ecosystem by natural power using sea water and control precipitation and the climate change of nearby area by using temperature difference of the upper atmosphere adjoining the water line.
