According to the Adirondack Chronology, the Haudenosaunee and the colonists agreed to a treaty in 1640 that would regulate the use of fire in hunting. Haudenosaunee hunting practices included burning large areas to divert big game such as deer, elk, and bison into unburned areas. Unburned areas, like impoundments, narrow chutes, rivers or lakes, and cliff edges, were much smaller open prairies or meadows, making it easier to catch the game. Additionally, these controlled fires promoted growth and restored nutrients for plant life. In 1640, the cultural practice of using fire in hunting became restricted because a treaty was enacted to regulate it.
