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>

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>",
