When early European settlers arrived in Western Oregon, they encountered a landscape quite different from what we see today. Much of the Willamette Valley was an open oak savannah, and the forests were a patchwork of new and old growth, reflecting centuries of intermittent fire. For many early visitors, this was the "natural" landscape - but in fact the native peoples of the area had been "managing" their environment for about 4,000 years, primarily through the use of fire. By using low-intensity spot firing in the Fall, the Kalapuya and other local peoples had learned how to maximize the landscape for the products they needed most - seed, textiles, wapato, and forage for game. In fact, they had maintained the Willamette, Umpqua and Rogue Valleys in a truly prehistoric state - since the last great climate change about 4000 years ago, when a wetter climate succeeded a long dry period.
