Layer: CHIS Prescribed Burn Perimeters (ID:0)

View In: Map Viewer

Name: CHIS Prescribed Burn Perimeters

Display Field: TREATMENT_NAME

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description:

The "rxburn" data layer contains perimeters from multiple agencies, representing prescribed fires, fire use, and jackpot burns, with associated tabular data for responsible agency, project number, project name, start date, 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 consistently.

V20_1 was released in April, 2021 and includes 482 fire related fuel treatments from: CALFIRE (287), NPS (7), BLM (6), and the USFS (182) from 2020.

Copyright Text: Includes input perimeters from CAL FIRE, contract counties, U.S. Forest Service, Bureau of Land Management and National Park Service and other organizations.
