Fire Disturbance Area Coordinate system: 4269 - "NAD83" Abstract: The Ministry of Natural Resources Fire Program records details about specific forest fires. This dataset contains the Fire Disturbance Area(s) represented by the mapped exterior perimeter of a forest fire. As of July 12, 2004 fire perimeters have been loaded back to 1960. Supplementary tables can be used and are available for download from the additional documentation section. Supplementary look-up table descriptions are available in the data description document, which is available for download from the additional documentation section. This layer is part of what was known as the OMNR Non-Fundamental Dataset.

  Purpose:

  Fire Perimeter Mapping is an important function of the Fire Management program to record areas burned by forest fires. The information that is collected is used for numerous operational and program management activities within the fire program and for forest management and other land-use planning activities.

  Supplemental Information:

  Legislated or Legal Authority for Collection: A Legal Requirement of the Forest Information Manual (FIM) to provide Sustainable Forest License (SFL) stakeholders for Annual Report of forest depletions. Additional Time Period Information: Fire Disturbance Areas are collected for each fire season (year). The Fire Disturbance Area NRVIS/OLIW model accommodates for forest fire history. Data is collected on an on-going basis therefore the time period 'end date' may be more recent than indicated above. Starting in 2005 as a result of the new Fire Management Strategy fires which were previously classified as OFR in the Far North of the Province (north of 54 degrees latitude) are reclassified as IFR Starting in 2005 as a result of the new Fire Management Strategy fire response objectives have changed: OBJECTIVE CODES 1989 TO 2004 SUP SUPPRESSION - denotes a dedicated attempt to control the fire. PRO PROTECTION - denotes an attempt to limit the spread of the fire in certain locations to protect values. MON MONITOR - denotes a fire on which no action was taken except for observations. Monitor also includes Prescribed Burns. OBJECTIVE CODES 2005 MOD MODIFIED - A Wildfire that is managed using a combination of suppression techniques, including direct and indirect attack as well as monitoring to steer, contain or otherwise manage fire activity within a pre-determined perimeter such that costs and/or damage are minimized, and/or benefits from the fire are maximized. MON MONITORED - A wildfire that is observed and assessed to determine the response option required to minimize social disruption and/or significant value and resource impacts while achieving beneficial ecological, economic or resource management objectives FUL FULL- A wildfire which requires immediate, aggressive initial attack and/or sustained suppression action until the fire is declared out MDP MODIFIED UNDER PRESCRIPTION - Initial attack using response options and suppression tactics to steer or contain the fire to minimize costs and damage and maximize any beneficial effects that may be associated with a fire in accordance with an approved burning prescription MNP MONITORED UNDER PRESCRIPTION - Observation and assessment of a fire to determine the need for full and/or modified response to minimize costs damage and social disruption while maximizing any beneficial effects associated with a fire in accordance with an approved burning prescription.

  Mapping is derived from a variety of sources (GPS points, digitized paper maps of various scales ranging from 1:20,000 to 1:250,000). Prior to 1998, only fires greater than 200 hectares were mapped. Since 1998, fires greater than 40 hectares have been mapped If adequate mapping exists for fires less than 40 hectares in size, they will be included in this Data Class. Prior to 1998, Forest Response Objectives were not recorded. For fires over 40 hectares that were not mapped, a buffer is generated that is proportionate to the recorded fire final size documented by the fire crewboss.The Fire Disturbance Area does not include unburned areas, or reflect tree mortality, severity of the forest fire, or any other impacts to the forest cover. The mapped Fire Disturbance Areas from the early decades of the 20th Century are coarse.There is not any Fire Weather Index information for fires between 1960 and 1962 and a value of 0.1 has been entered into NRVIS. These values will be changed to blank once the new version of NRVIS is released which is scheduled for October, 2004.
