This dataset combines CAL FIRE data and EBRPD research on historical fires in Contra Costa and Alameda Counties. The earliest fire is from 1905, and this dataset will be updated with new fires on a yearly basis. Summary from CAL FIRE data: Provides a reasonable view of the spatial distribution of past large fires. Due to missing perimeters (see Use Limitations) this layer should be used carefully for statistical analysis and reporting. Please contact the CAL FIRE Fire and Resource Assessment Program for a detailed explanation of the limitations of the data. |

CAL FIRE recognizes the various partners that have contributed to this dataset, including USDA Forest Service Region 5, USDI Bureau of Land Managment, National Park Service, National Fish and Wildlife Service, and numerous local agencies. EBRPD researched fires were developed by EBRPD staff around 2011. |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This dataset is a compilation of data sources including EBRPD research by J. Kent and CAL FIRE FRAP data sources. EBRPD researched fires are likely from historic newspaper articles, fire lookout records, and similar sources. The exact source for each fire is unknown, but they are presumed to be extensively researched. The fires from the Burn_Area dataset were mapped via GPS or airphoto by EBRPD staff between 1995 and 2004, approximately. </SPAN></P><P><SPAN> The schema of this combined dataset utilizes the CAL FIRE schema for "Incidents" or wildfires. Prescribed fires (from CAL FIRE FRAP) and EBRPD researched fires were appended to this schema, with a few fields added for clarity on sources. This dataset is inherently incomplete, some information may be inaccurate, and fire perimeters, particularly those sourced to EBRPD or older fires, are approximate. Not all fires in the East Bay are included in this dataset and care should be taken when conducting analysis or estimating acres. Fires include only those that overlap with Contra Costa or Alameda Counties. They are not clipped to the county boundary to maintain the entirety of fire perimeters.</SPAN></P><P><SPAN>Complete list of data sources:</SPAN></P><UL><LI><P><SPAN>Burn_Area</SPAN></P></LI></UL><P><SPAN>NOTE:
Data from the Y drive have been archived and are no longer at these locations. Fires from CAL FRAP will be added on a yearly basis.</SPAN></P><P><SPAN>Data compiled by Maryrose Kulick, GIS Technician, October 2022</SPAN></P></DIV></DIV></DIV> |

<DIV STYLE="text-align:Left;"><DIV><DIV><P STYLE="margin:0 0 14 0;"><SPAN>CAL FIRE NOTES:</SPAN></P><P STYLE="margin:0 0 14 0;"><SPAN>This is the most complete digital record of fire history in California. However it is still incomplete in many respects. Fires may be missing altogether or have missing or incorrect attribute data. Some fires may be missing because historical records were lost or damaged, were too small for the minimum cutoffs, had inadequate documentation or have not yet been incorporated into the database. The 2008 Lone Pine fire perimeter has been omitted, we hope to include it in the next update. </SPAN></P><P STYLE="margin:0 0 14 0;"><SPAN>Other errors with the fire perimeter database include duplicate fires and over-generalization. While the data capture process attempts to identify duplicate fires resulting from multiple data sources (e.g., the USFS and CAL FIRE both captured and submitted the fire perimeter), some duplicates may still exist. Additionally, over-generalization, particularly with large old fires may show unburned "islands" within the final perimeter as burned. Users of the fire perimeter database must exercise caution in application of the data. Careful use of the fire perimeter database will prevent users from drawing inaccurate or erroneous conclusions from the data.</SPAN></P></DIV></DIV></DIV> |
