South Umpqua Falls in Winter, South Umpqua River, Douglas County, Oregon (J. Laurance, December 10, 2009).

[July 20, 2020 Note: This study was originally undertaken in 2010 for Douglas County in order to determine precontact forest conditions (ca. 1800 to 1825) for US Forest Service lands on the headwaters of the South Umpqua River, above Tiller, Oregon. The following edited and updated links show the sources of information and research methods used to predict those conditions. The current purpose of this update is to better interpret 1930s Osborne photos taken from fire lookouts within the study area: A more detailed description of website edits is provided in the Footnote at the bottom of this page.]

The purpose of this study is to produce a reliable landscape-scale description of late precontact (pre-1826; ca. 1800) reference forest conditions for the eastern portion of present-day Tiller Ranger District of the Umpqua National Forest in Douglas County, Oregon. The primary intended use of this information is to help update Community Wildfire Protection Plans.

The resulting description has been assembled from a comprehensive range of cultural, historical, and contemporary sources of information and results are displayed in a wide variety of formats -- including maps, texts, tables, photographs, video, GIS layers, and Internet -- in order to reach the broadest possible audience over time, to provide full transparency in how these materials were assembled and interpreted, and to encourage optimum practical uses of these documentary resources.

Footnote. Links to most text and video portions of the 2010 report's final written and online drafts have been removed, while focus is on transferring and re-linking of historical and documentary photographs, maps, General Land Office survey notes, and GIS layers to greatly enhance interpretation of the Osborne photos. QTVR files have also been retained, but now require special "legacy" software to use. Xcel database files containing GPS data on individual photographs and panoramas remain mostly undeveloped as planned discrete links and geographical webpages, but the entire dataset remains available on the Photographs link.
