Native American use of fire (and its effects on water)

Native Americans have a long history of traditional fire use on Mother Earth. Fire use promoted their desired ecological state of the environment. These traditions and time of season to burn for a desired effect have been passed down generation to generation. Henry T. Lewis, who has authored more books and articles on this subject than anyone else, concluded that there were at least 70 different reasons for the Indians firing vegetation. These reasons included hunting, crop management, insect collection, pest management, improving growth and yields, fireproofing areas, clearing areas for travel, felling trees, and clearing riparian areas just to name a few.
