The LANDFIRE (LF) Canadian Forest Fire Danger Rating System (CFFDRS) product depicts fuel types as an identifiable association of fuel elements of distinctive species, form, size, arrangement, and continuity. CFFDRS exhibits characteristic fire behavior under the specified burn conditions. In LF 2022 Canadian fuel models are derived from the Fuel Model Guide to Alaska Vegetation (Alaska Fuel Model Guide Task Group, 2018) and subsequent updates. The LF CFFDRS product contains the fuel models used for the Fire Behavior Prediction (FBP) system fuel type inputs. Default values assigned to the Canadian Fuel Models required to run the Prometheus fire behavior software (Prometheus, 2021) are added as attributes to the LF CFFDRS product. To designate disturbed areas where CFFDRS is modified, the aggregated Annual Disturbance products from 2013 to 2022 in the Fuel Disturbance layer are used. All existing disturbances between 2013-2022 are represented in LF 2022 and the products are intended to be used in 2023, the year of release. The "capable" year terminology used in LF 2020 and LF 2016 Remap is no longer specified given the reduction in latency from when a disturbance occurs to the release date of fuel layers accounting for that disturbance. However, users should still consider adjusting fuel layers for disturbances that occurred after the end of the 2022 fiscal year (after October 1st, 2022) when using the LF 2022 fuel layers, as those changes would not be accounted for.

Customized products were created for fire management partners in Alaska by leveraging projected Canadian Forest Fire Danger Rating System metrics produced by Young et al. (2025). This input dataset contains daily projections from 1980 through 2099 for key fire danger metrics including Buildup Index, Drought Code, Duff Moisture Code, Fine Fuel Moisture Code, Fire Weather Index, and Initial Spread Index. Using Python and R, we processed these data to produce summary tables, time series plots, and maps tailored for fire management decision support. Most outputs were spatially summarized to 16 Fire Danger Rating Areas, corresponding to the boreal forest extent of the input dataset. These climate-informed projections provide insights into fire danger by capturing changes in fuel moisture, drought, and shifting precipitation and temperature patterns. The resulting data products aim to provide actionable, locally relevant fire danger information to support fire planning and management under future conditions in Alaska.

The LANDFIRE (LF) Canadian Forest Fire Danger Rating System (CFFDRS) product depicts fuel types as an identifiable association of fuel elements of distinctive species, form, size, arrangement, and continuity. CFFDRS exhibits characteristic fire behavior under the specified burn conditions. In LF 2016 Remap (LF Remap) the attribute table for the CFFDRS product is a Look Up Table (LUT) software called Prometheus. Prometheus was designed to allow a user on the ground, at a fire, to have a preference of fuel type depending on the situation and the fire environment. In Prometheus, the generic planning grid developed pre-season is populated with choices so that the user in the field can choose which is most appropriate at that given moment.

Hazardous forest types for wildland fire means forest types assessed as being associated with the risk of high to extreme wildland fire. This data is intended to help inform where further assessment is required and is to be used in conjunction with guidance from the Ministry of Natural Resources and Forestry .

Fire perimeters for this year's forest fires in Ontario. Fire perimeters are illustrations only and may not be exact in relation to actual physical locations. The Ontario Ministry of Natural Resources does not capture perimeters for every fire. Fire perimeters are not captured in real time; each capture depends on available resources and weather conditions and may be several days old. During fire season, perimeter data is updated every 24 hours as improved information becomes available; therefore, reported fire size may fluctuate from day to day. The Ontario Ministry of Natural Resources shall not be liable in any way for the use of, or reliance upon this information. The [Forest Fire Info Map](https://www.lioapplications.lrc.gov.on.ca/ForestFireInformationMap/index.html?viewer=FFIM.FFIM&locale=en-CA) shows active fires, current fire danger and restricted fire zones in place due to high fire danger.
