LEAVES AND VEGETATION
Next heap leaves, grass, ferns, moss, pine needles, brush or tree boughs over the framework. The vegetation can be wet. Live materials can be used, but dead materials are best. A layer of vegetation two to three feet thick covering both sides of the shelter should be enough to keep you dry inside.
BARK AND BRUSH**
The rounded dome of a leaf hut resists most wind and water, but bark slabs can be used as shingles for even better weather resistance. Remember that these huts are water resistant, not water proof. A layer of brush (sticks, twigs and branches) should be thrown over the whole dome to keep the wind from stripping the debris away. Natural shelters like this are difficult to see from a distance, so mark it with a scrap of colored cloth or plastic.
