LANDFIRE Reference Data

LANDFIRE (LF) would like to acknowledge and thank everyone who has contributed data. LF collects data through user submitted data contributions and by searching for data on websites and agency databases/Systems of Record (SOR). The Website Agency DB Table provides a list of websites or agency databases/SOR from which LF acquires data.

LF has transitioned to annual updates and needs as much time as possible to process data. LF is asking for data to be submitted or available in database systems by October 31st. Please make every effort to have your FY 2023 data accessible to LF by October 31, 2023. Data accessibility may include entering data into online databases/Systems of Record (SOR) so it can be obtained by LF. Data submitted after the deadline will be used if schedules allow. All data contributions must meet LF requirements.

The primary focus of this data call is to collect FY 2023 disturbance and treatment activities. To make annual updates possible we will be asking for data from the fiscal year which runs from 10/01/2022 – 09/30/2023. LF now requires disturbance/treatment date or fiscal year to be included with your data submission,. This will ensure your data are processed correctly. The secondary focus is to collect vegetation/fuel plot data. LF also welcomes feedback on current products.

LF needs your help to collect four types of data:

• Disturbance/Treatment polygons: Disturbance and treatment polygons are first priority data for updates (LF 2012, LF 2014, etc.) and are processed and maintained in the LF Events Geodatabase.

  Disturbance Types Wildfires Development Weather Damage Insects & Disease Treatment Types Harvest/Thinning Mechanical Prescribed Fires Seeding/Planting Chemical

  Attributes: Required Disturbance/Treatment type Disturbance/Treatment fiscal year   Attributes: Optional/Important Disturbance/Treatment name Start date End date Severity Reporting entity/agency Notes (e.g., effects on vegetation or fuel)

• Vegetation and Fuel Plot data:Vegetation and fuel plot data are the first priority data for mapping (LF c2001 / LF Remap) and are processed and maintained in the LF Reference Database (LFRDB)

  Plot Theme	format
  geo-referenced vegetation and fuel conditions	tabular - text files, spreadsheets, relational databases
  	Spatial- shapefiles, geodatabases, coverages

• Invasive Species Data: LF is accepting submissions of polygon or plot based invasive species data.
• Lidar Data Lidar data are first priority data for mapping (LF Remap) and will be used to develop vegetation structure models.

  LF uses airborne lidar data collections to develop vegetation structure models. Please provide links and contact information to obtain data that are available to the public.
  
  If data are not publicly accessible, please contact the LF Reference Data Administrator to determine the best method for transfer.

• Feedback on LF products: Feedback is secondary priority data for updates and remaps.
  Submit feedback through the LF Help Desk.
