__The link: * Access the data directory* is available in the section*Dataset description sheets; Additional information*__. The Harvest and other silvicultural interventions mapping is produced as part of the ecoforest inventory of southern Quebec in order to maintain an up-to-date portrait of the forest. Several stakeholders related to forest operations participate in maintaining this forest portrait, including the Regional Operations Sector of the Ministry of Natural Resources and Forests (MRNF), private forest development agencies and major landowners. This map contains information on forest interventions carried out on the territory (e.g. harvesting, thinning, reforestation) as well as the year of the work. The period of work begins at the beginning of the 20th century (when information is available) to the present day. The associated information is presented as a series of overlays of interventions. This map covers the commercial territory of public forests and private forests in Quebec. The minimum mapping area is 0.1 ha. Note: When there is more than one intervention on the same territory during the same year, priority is given to the one that changes the forest cover in a sustainable manner (e.g. planting). To have access to all the interventions for the same year (in public forests only), please consult the technical and financial activity reports (RATF) distributed by the Ministry's Regional Operations Sector on the government website of Data Québec.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The forest fire map shows forest fires that occurred mainly in the territory of southern Quebec, i.e. the area located south of the territorial limit of attributable forests. This map data makes it possible to improve knowledge about fire regimes and to meet the specific needs of special management plans following forest fires. They can also be used to meet a variety of study and research needs, such as analyzing the impact of climate change, modeling post-fire regeneration, and studying ecosystem dynamics. This information is obtained from and produced from a variety of sources, including satellite images, aerial photographs, field or aerial surveys, fire scar dating, and archival documents. This data contains four types of mapping as well as fire regime mapping: • Detailed fire mapping, from 1976 to the present. This mapping includes burn types, total burn and partial burn, when information is available. In addition, for fires that have been characterized, information on the classes of burning patterns is added. The minimum mapping area can be up to 0.1 ha, depending on the source products used. This map is partially available for areas located in the north of southern Quebec. • Mapping the simplified contours of fires, from 1972 to today. This map shows the external contours of fires (without fragmentation), in order to represent them globally in a product that is easily usable and can be integrated into current information systems, GPS or others. Resulting from the fusion of detailed fire mapping, this product was designed to meet various customer needs. This map is partially available for the sectors located in the north of southern Quebec. • The mapping of the origin of fires having been listed by the protection organizations (e.g.: SOPFEU) for the period from 1972 to today. This mapping includes the date, the source of ignition (human or lightning) and the protection zone. It is available for all of Quebec. • The mapping of ancient fires concerns fires that occurred between the very end of the 19th century and 1975. This mapping comes from the information present on the forest maps of the first and second inventories, as well as from the information contained on the ecoforest maps of the third and fourth inventories. The dating of these fires is done using various methods, including the analysis of study trees bearing fire scars and the consultation of archival documents. This data is available for the following regions: Saguenay-Lac-Saint-Jean (02), Bas-Saint-Laurent (02), Bas-Saint-Laurent (01), Gaspésie-Îles-de-la-Madeleine (11), Abitibi-Témiscamingue (08), Mauricie-Centre-du-Québec (04-17), and Lanaudière-du-Québec (04-17), and Lanaudière-Laurentides (14-15). • Mapping fire regimes in southern Quebec. This map shows 13 zones with distinct fire regimes. These areas were delineated based on available information on the areas burned during the period 1890-2020 and other potentially decisive environmental variables, such as physiography, the abundance of different tree species known to be dependent on fire as well as the location of natural and anthropogenic ignitions. Fire regime mapping covers all forest areas under management as well as a more northern portion that is not managed. The detailed methodology is presented in Forest Research Paper no. 189 “Zoning fire regimes in southern Quebec” (coming soon). This zoning may be useful to ensure better consideration of the risk of fire in a forest management context. It can also serve as a territorial basis for projecting future fire activity taking into account various factors, such as climate change, fire suppression as well as changes in the types of fuels and their distribution on the territory.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
