| | American Indian Use of Fire in Ecosystems References |
 | | In addition, there is extensive documentation of tribes changing water flow (canals), practicing farming, grazing (horses, sheep, and cattle since the 1600s), using vegetation, wood, and bone for decorative arts, minerals for many uses, and building structures of wood, rock, and ice. |
 | | For those Indian tribes that used fire in ecosystems tended to burn in the late spring just before new growth appears, while in areas that are drier fires tended to be set during the late summer or early fall since the main growth of plants and grasses occurs in the winter. |
 | | Notes that 35 tribes in California used fire to increase the yield of seed crops, 33 tribes used fire to drive game, and 22 tribes used fire to stimulate the growth of wild tobacco. |
