posted 2022-08-31 [Disturbance] LF 2016 Remap (LF Remap) Annual Disturbance products for the years 2015 and 2016 attribute tables were updated ...

Reason for alert: LF 2016 Remap (LF Remap) Annual Disturbance products for the years 2015 and 2016 attribute tables were updated and the products have been re-released for some extents.

Updated product(s) or information: Annual Disturbance 2015 and 2016 were updated on 08/31/2022. Extents impacted include the Conterminous United States (CONUS) and the Insular Areas (IA) including Puerto Rico and the U.S. Virgin Islands (PRVI), The Federated States of Micronesia, Guam and the Commonwealth of the Northern Mariana Islands, and Palau.

Problem or issue description: LF Remap Annual Disturbance 2015 and 2016 products were updated to correct a mis-color within the RGB columns of the attribute table (both the Raster Attribute Table (RAT) joined to the TIF and the stand-alone csv). Previously the value 1101 Unknown Low Severity was color coded red, when it should have been gray. This mis-color has now been corrected. Note that the 1101 Unknown Low Severity values were assigned correctly, this re-release is only a color correction.

Users are advised to download the updated versions of the LF Remap Annual Disturbance 2015/2016 products for both CONUS and IA and/or download the corrected stand-alone csv. We encourage users to delete any local copies of these products that were downloaded prior to 08/31/2022. We regret any inconvenience this may cause.

posted 2021-11-01 [Fuel] Updates to the LANDFIRE (LF) 2016 Remap Fuel Characteristic Classification System Fuelbeds (FCCS) 2020 capable fuels product

Updates to the LANDFIRE (LF) 2016 Remap Fuel Characteristic Classification System Fuelbeds (FCCS) 2020 capable fuels product:

Reason for the alert: An LF 2016 Remap FCCS fuel bed linked was incorrectly linked to a vegetation type in 20 map zones located in the South Central, Southeast, and Northeast GeoAreas.

Updated product(s) or information: LF 2016 Remap (LF 2.0.0) FCCS 2020 capable fuels products were updated on 11/01/2021. The issue is limited to 20 map zones in the South Central, Southeast, and Northeast GeoAreas of CONUS, but mosaics were also impacted.

Problem or issue description: A fuel bed within LF 2016 Remap (LF 2.0.0) 2020 capable fuels products was incorrectly linked to a vegetation type in twenty map zones (SC z32, z35, z36; SE z37, z44, z45, z46, z48, z54, z55, z56, z58, z98, z99, and NE z47, z49, z57, z59, z60, z61) located in the South Central, Southeast; and Northeast GeoAreas. The misprint in the look-up table (LUT) that associates the fuel bed to the vegetation type, showed that FCCS fuel bed 538 Pacific Limestone Forest was linked to Existing Vegetation Type (EVT)/Fuel Vegetation Type (FVT) 2575 Southeastern Ruderal Grassland and Shrubland. The correct association should be FCCS fuel bed 519 Southern Ruderal Grassland to EVT/FVT 2575 Southeastern Ruderal Grassland and Shrubland. The FCCS Master Database will also be updated to reflect this change.

Users are advised to download the updated versions of the LF 2016 Remap FCCS 2020 capable fuels products and FCCS Master Database and delete any local copies that were downloaded prior to 11/01/2021. We regret any inconvenience this may cause.

posted 2019-06-17 [Fuel|Disturbance] Change to LF Remap fuels for disturbed areas represents effective year 2019...

Change to LF Remap fuels for disturbed areas represents effective year 2019.

Reason for alert: Users of existing LANDFIRE (LF) fuel products need to be aware of a change in the products being released as part of Remap.

LF version(s): LF Remap (LF 2.0.0)

Updated product(s) or information: Areas mapped as disturbed by LF have been adjusted to account for vegetation conditions relative to Time Since Disturbance (TSD) for the 2019 effective year (accounting for disturbances between 2009 - 2016). This adjustment has been made to the following LF Remap products:

13 Anderson Fire Behavior Fuel Models (FBFM13)
40 Scott and Burgan Fire Behavior Fuel Models (FBFM40)
Forest Canopy Cover (CC)
Forest Canopy Height (CH)
Forest Canopy Bulk Density (CBD)
Forest Canopy Base Height (CBH)
Fuel Vegetation Type (FVT)
Fuel Vegetation Cover (FVC)
Fuel Vegetation Height (FVH)
Fuel Disturbance (FDist)
Historical Disturbance (HDist)

Problem or issue description: The significant refinement for the LF Remap products mentioned above, is that they represent "capable" fuels, meaning the TSD assignments have been calculated using an effective year. For example, LF Remap fuels are now assigned for the 2019 effective year. The new process considers all incorporated disturbances in LF Remap and provides an adjustment factor to account for the TSD, making the data "capable" of representing an effective year. These capable data account for increase or decrease in fuel attributes in disturbed areas to the effective year (2019 in this case).

Given that LF Remap is circa 2016 data, it is important to note that no new disturbances are added for 2017 through 2018. Although these new disturbance data are not available yet, they are being cataloged for future use in an Update. Disturbances older than 10 years in 2019 follow the existing LF protocol for removal from Fuel Disturbance and are represented by more recent non-disturbed LF Remap vegetation. For areas that have not been disturbed, fuel is based on LF Remap vegetation, which is the newest fuel vegetation available.

The objective for this change was to improve, clarify, and simplify fuel transitions and Fuel attribute change following disturbances. By synchronizing TSDs, users may not need to do much, if any adjustments, to the vegetation and fuel conditions to represent contemporary conditions. In addition, these refinements will improve performance of fire behavior modeling when using the data operationally. Starting with the Southwest GeoArea release (which includes Northwest GeoArea fuel products), LF Remap fuels will be delivered as capable fuels for the 2019 effective year.
