Islands Made of Reeds on Lake Titicaca
High in the Andes Mountains, between Peru and Bolivia, lies Lake Titicaca. It is one of the highest large lakes in the world that boats can use. On its Peruvian side, a group of people called the Uros live on islands that they build themselves out of plants.
The plant is a tall reed called totora. It grows in shallow water along the shore. The people cut the reeds and pile them in thick layers, with new ones laid on top of the old. Because the reeds are full of tiny air pockets, they float. The bottom layers slowly rot in the water, so fresh reeds must be added all the time to keep the island firm.
Reeds are used for much more than the ground. Houses are built from them, and so are the boats, some shaped like big curved baskets. The stems can even be eaten. Many visitors learn about the lake and the Uros way of life on guided tours.
An island of totora can be moved if needed. Long ropes and anchors hold it in place, and it can be cut apart and pulled to a new spot. The Uros show how people can shape a home from whatever their land gives them.
