Four sites, including a diversity of oil types burned and habitats, were selected for follow-up review and evaluation of the effects of in-situ burning (ISB); Mosquito Bay spill in Louisiana, burned in April 2001, Lakehead Pipe Line spill in Ruffy Brook, Minnesota, burned in July 2000, Louisiana Point pipeline spill, burned in February 2000, and Chevron Pipe Line Milepost 68 near Corinne, Utah, burned twice, in March and APril 2000. Site visits were conducted in July (Minnesota and Utah) and October (two sites in Louisiana). All available data on each site were collected from those involved in the burns and the post burn monitoring. State and local monitoring data provided additonal information. The site was photographed from the same position and perspective as photographs taken during and shortly after the spill and burn, creating time-series photography as a visual record of the use of in-situ burning and vegetative recovery. In combination with quantitative field measurements, photography provides an excellent understanding of the specific site conditions and how the results might apply to other sites. Because this report includes a large number of color photographs for the sites, which would make traditional printing of hardcopy reports very expensive, the report is being published in digital format on CD-ROM
