Gather as many different kinds of seeds as possible from plants native to the area. With these seeds and some soil, make little balls.
Mix seeds with compost or planting soil, then add clay. Add just enough water to make the mixture damp. If you add too much water, the seeds will sprout too soon. Make small balls out of this mixture. Let them dry for a few days in the sun. Just before or during the rainy season, go to the area where you want to restore plant life and toss the balls out. Building contour trenches and other barriers there first will reduce and retain surface runoff water which is needed to help the seeds sprout and grow.
The seeds will sprout when it rains. The compost provides nutrients, and the clay prevents the seeds from drying out, being eaten by mice or birds, or blowing away. After a year the new plants will make their own seeds, and before long many new plants will grow. Soil will build up around the plants, preventing erosion. Soon, other kinds of plants will appear. If it is not disturbed, after many years the whole area will be restored.
Editor’s note: This method is good for restoring plant life, but it is not suitable for reforestation. Trees often need more care and time to grow.
