From where did the iroquois clothing, food, materials, and shelter come?

For food during the long winter months, the Iroquois gathered nuts, berries and root vegetables from their woodland environment. They also harvested maple syrup, sourced medicinal plants and hunted or fished for meat.
Construction materials for Iroquois housing, including timber, elm bark and tree fiber ropes, were also obtained from the woodland.
