Contribute Your Data to LANDFIRE

LANDFIRE would like to acknowledge and thank everyone who has contributed data. We rely on high-quality disturbance, treatment, vegetation, and fuel data from agencies and partners to maintain accurate landscape products. User contributions help ensure we can produce reliable annual updates.

Contribute Your Disturbance & Treatment Polygons

Disturbance and treatment polygons (also known as events) are a top priority for annual updates and are stored in the LF Disturbance and Treatment Polygon Geodatabase (formerly known as the Events Geodatabase). Refer to the LANDFIRE Data Collection Requirements for required attributes. LF processes data by fiscal year and requires that the disturbance/treatment date or federal fiscal year be included with all data submissions.

Collection Dates: October 1st (previous year) through September 30th (current year).

Deadline to Submit: All submissions must be in partner systems or emailed to LANDFIRE by October 31st.

Database Pulls: LF always pulls data from USDA Forest Service Activity Tracking System (FACTS), Interior Fuels & Post-fire Reporting System (IFPRS), National Interagency Fire Center (NIFC)/(InFORM), and USFS Insect/Disease. The Contributing Agency Database, linked below in Supplemental Resources, lists other websites or agency databases that LF has collected data from. If your dataset is listed in the database, confirm it has been updated and submitted prior to the September 30th deadline every year.

Data Format: We accept data in various formats including ESRI shapefiles, geodatabases, and ArcInfo coverages. Supporting information, including definitions of the fields and any codes in the data tables, should accompany the data to ensure correct interpretation.

Submit Data Directly to LANDFIRE: All data should be submitted to Brenda Lundberg, LANDFIRE Reference Data Administrator at blundberg@contractor.usgs.gov.

State Contributors

LANDFIRE relies on state and local data to help fill holes and create the best products possible. While LF may receive some data through federal databases, we are also looking for state treatment and disturbance data.

The map below shows the states where state agencies did and did not submit disturbance and treatment data for LF 2025. If your state is colored purple, it indicates that LF received disturbance and treatment data from your state agencies, with the contributed polygons shown. All states colored orange, show where LF can use state contributed data! Map does not show contributions from NIFC/InFORM or Federal Agencies.

Your Disturbance and Treatment Polygons at Work

So, you submitted your data and you want to know when it will show up. LANDFIRE creates and releases an early, Limited Annual Disturbance (LDist) product that uses only National federal events including FACTS, IFPRS, NIFC, USFS Insect/Disease. We also get National data submissions from the Bureau of Land Management (BLM) and the National Park Service (NPS).

The Preliminary Annual Disturbance (PDist) product is sequentially released with each Geographic Area. All submitted state and local disturbance and treatment polygons collected by the October 31st deadline are included in the PDist product and are what feeds into the Vegetation and Fuels products.

A final pull from Federal databases is done early June, with these events being added to the Final Annual Disturbance (Dist) product. Final Annual Disturbances will only influence Vegetation and Fuels products for the next years’ products.
