Other known errors with the fire perimeter database include duplicate fires and over-generalization. Over-generalization, particularly with large old fires, may show unburned &quot;islands&quot; 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. This dataset may differ in California compared to that available from the National Interagency Fire Center (NIFC) due to different requirements between the two datasets.  The data covers fires back to 1878. </span><span style="font-family:&quot;inherit&quot;, serif; font-size:12pt;"> </span></p><p style="background-image:initial; background-position:initial; background-size:initial; background-repeat:initial; background-attachment:initial; background-origin:initial; background-clip:initial; line-height:normal;"><b><span style="font-size:12pt; font-family:&quot;inherit&quot;, serif; color:black; background-image:initial; background-position:initial; background-size:initial; background-repeat:initial; background-attachment:initial; background-origin:initial; background-clip:initial;">Please help improve this dataset by filling out this survey with feedback:</span></b></p><p style="background-image:initial; background-position:initial; background-size:initial; background-repeat:initial; background-attachment:initial; background-origin:initial; background-clip:initial; line-height:normal;"><a href="https://survey123.arcgis.com/share/b296589b82af45f1ad9298d11a2fb5d3?portalUrl=https://CALFIRE-Forestry.maps.arcgis.com" style><span style="font-size:12pt; font-family:&quot;inherit&quot;, serif; background-image:initial; background-position:initial; background-size:initial; background-repeat:initial; background-attachment:initial; background-origin:initial; background-clip:initial;"><font color="#6495ed">Historic Fire Perimeter Dataset Feedback (arcgis.com)</font></span></a></p><p style="background-image:initial; background-position:initial; background-size:initial; background-repeat:initial; background-attachment:initial; background-origin:initial; background-clip:initial; line-height:normal;"><span style="font-size:12pt; font-family:&quot;inherit&quot;, serif;"> </span></p><p style="background-image:initial; background-position:initial; background-size:initial; background-repeat:initial; background-attachment:initial; background-origin:initial; background-clip:initial; line-height:normal;"><b><span style="font-size:12pt; font-family:&quot;inherit&quot;, serif; color:black; background-image:initial; background-position:initial; background-size:initial; background-repeat:initial; background-attachment:initial; background-origin:initial; background-clip:initial;">Current criteria for data collection are as follows:</span></b></p><p style="background-image:initial; background-position:initial; background-size:initial; background-repeat:initial; background-attachment:initial; background-origin:initial; background-clip:initial; line-height:normal;"><span style="font-size:12pt; font-family:&quot;inherit&quot;, serif; color:black; background-image:initial; background-position:initial; background-size:initial; background-repeat:initial; background-attachment:initial; background-origin:initial; background-clip:initial;">CAL FIRE (including contract counties) submit perimeters ≥10 acres in timber, ≥50 acres in brush, or ≥300 acres in grass, and/or ≥3 impacted residential or commercial structures, and/or caused ≥1 fatality.</span></p><p style="background-image:initial; background-position:initial; background-size:initial; background-repeat:initial; background-attachment:initial; background-origin:initial; background-clip:initial; line-height:normal;"><span style="font-size:12pt; font-family:&quot;inherit&quot;, serif; color:black; background-image:initial; background-position:initial; background-size:initial; background-repeat:initial; background-attachment:initial; background-origin:initial; background-clip:initial;">All cooperating agencies submit perimeters ≥10 acres.</span></p><p style="background-image:initial; background-position:initial; background-size:initial; background-repeat:initial; background-attachment:initial; background-origin:initial; background-clip:initial; line-height:normal;"><b><span style="font-size:12pt; font-family:&quot;inherit&quot;, serif; color:black;">Version update:</span></b></p><p style="margin-bottom:0in; background-image:initial; background-position:initial; background-size:initial; background-repeat:initial; background-attachment:initial; background-origin:initial; background-clip:initial; line-height:normal;"><span style="font-size:12pt; font-family:&quot;inherit&quot;, serif; color:black; background-image:initial; background-position:initial; background-size:initial; background-repeat:initial; background-attachment:initial; background-origin:initial; background-clip:initial;">Firep23_1 was released in May 2024. Two hundred eighty four fires from the 2023 fire season were added to the database (21 from BLM, 102 from CAL FIRE, 72 from Contract Counties, 19 from LRA, 9 from NPS, 57 from USFS and 4 from USFW).  The 2020 Cottonwood fire, 2021 Lone Rock and Union fires, as well as the 2022 Lost Lake fire were added.  USFW submitted a higher accuracy perimeter to replace the 2022 River perimeter.  Additionally, 48 perimeters were digitized from an historical map included in a publication from Weeks, d. et al. The Utilization of El Dorado County Land. May 1934, Bulletin 572.  University of California, Berkeley.  Two thousand eighteen perimeters had attributes updated, the bulk of which had IRWIN IDs added. A duplicate 2020 Erbes perimeter was removed.  The following fires were identified as meeting our collection criteria, but are not included in this version and will hopefully be added in the next update: Big Hill #2 (2023-CAHIA-001020).  </span><span style="font-family:&quot;inherit&quot;, serif;
