How to write the first level of the sign to protect young trees?

Green environmental protection, starting from me.

After the young trees are planted, the soil next to the young trees must be leveled and filled to facilitate the growth of the roots of the young trees. No one is allowed to borrow soil near the small tree, because once the soil next to the small tree is taken away, the roots of the small tree cannot absorb water and nutrition well. It is forbidden to hang things on small trees, dry clothes or use trees as support rods.

China Arbor Day is scheduled for March 12 every year, which is a festival determined by legislation in order to stimulate people's enthusiasm for forest planting, promote land greening and protect the ecological environment on which human beings depend. In China, Tomb-Sweeping Day was designated as Arbor Day in 19 15, which was first proposed by Lin Daoyang and others. Later, it was changed to 12 March and Sun Yat-sen died 1928 to commemorate the revolutionary pioneer's wish to plant trees.
