Saejang is made of hard wood, such as a birch or chestnut tree. He is also a patron for the UK charity Chestnut Tree House. This is the northernmost reach of the chestnut tree. The name "chestnut" derives from the color of the nut of the chestnut tree. Berre is located at the altitude limit where the chestnut tree replaces the olive tree. Large-scale cultivation of the chestnut tree was introduced in Corsica during the Genoese domination. Just past the overlook, the road passes numerous large chestnut tree blowdowns. The sweet chestnut tree grows well on limestone-free, deeply weathered soil. A single giant chestnut tree in the Smokies could yield 18,000 planks of lumber.
