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 database systems.

As LF continues to work towards the goal of annual updates, LF needs as much time as possible to process data. LF is asking for data to be submitted or available in data base systems one month earlier than in previous years. The new data submission deadline is October 31st. Please make every effort to submit your data by October 31 of each year, as LF is relying heavily on user contributed data for this update. Data submitted after the deadline will be used if schedules allow or be archived for future use. All data contributions must meet LF requirements.

The primary focus of this data call is to collect FY 2022 disturbance and treatment activities. To make annual updates possible we will be asking for data from the fiscal year which runs from 10/1/2021 – 9/30/2022. LF is asking for a new required attribute that must be included with your data submission, disturbance/treatment date or fiscal year. This will ensure your data are processed correctly. The secondary focus is to collect both vegetation/fuel plot data and invasive species polygons and plots. 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 year   Attributes: Optional/Important Disturbance/Treatment name Start date End date Severity Reporting entity/agency Notes (e.g., effects on vegetation or fuel)

• 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.

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