Prescribed fires alter fuel conditions and this data is used to update fuel models maintained by CAL FIRE, the U.S. Forest Service, Bureau of Land Management and National Parks Service and other organizations. In addition, past treatments are tracked as part of the periodic California Strategic Fire Plan in order to identify "success stories" involving lowering costs and losses from these pre-fire projects. |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The "rxburn" data layer contains perimeters from multiple agencies of various prescribed burns, with associated tabular data for responsible agency, contract number, project name, start date, and acres reported and more. Data provided are merged from sources of varying quality. There has been a significant amount of work to resolve duplicate prescribed fires (from different sources). This layer is a best attempt, does not include complete data for all agencies. Two of the attributes in this dataset, PRE_CON_CLASS and POST_CON_CLASS are based on an abstract concept called "Condition Class." There is more information about "Condition Class" in the Overview Description / Entity and Attribute Overview section. Those two attributes are not collected consistantly.</SPAN></P><P><SPAN>V19_1 was released in april 29th, 2020 and includes 985 new rx burns from: CALFIRE (89), NPS (5), and BLM. The USFS submited 250 burns from 2018 and 581 from 2019. The date format was changed from YYYYMMDD to MMDDYYYY. Thirty-seven treatments (preparation, hand pile and machine pile) were moved out of this feature class and into the Non_RXFire_Legacy13_2 feature class.</SPAN></P></DIV></DIV></DIV> |

<DIV STYLE="text-align:Left;"><DIV><DIV><P STYLE="margin:0 0 14 0;"><SPAN><SPAN>This is the most complete digital record of prescribed 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 burns 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. </SPAN></SPAN></P><P STYLE="margin:0 0 14 0;"><SPAN>Other errors with the fire perimeter database include duplicate fires and over-generalization. The data capture process attempts to identify duplicate fires resulting from multiple data sources (i.e. 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><P><SPAN /></P></DIV></DIV></DIV> |
