The portrait of forest cover in Quebec is an assembly made from the up-to-date ecoforest map of the inventory of southern Quebec and vegetation maps from the northern ecoforest inventory and Northern Quebec. Administrative divisions, forest boundaries and territories where forest management responsibilities and obligations are under the responsibility of the municipal environment are also added. Then, an update is carried out for areas that have a predominant use other than forest, including the road and rail network, energy transmission lines, cultivated land and built environments. The portrait makes it easy to calculate the rate of land use by forests in the territory of a municipality, an unorganized territory, an indigenous territory, an MRC or an administrative region, then to draw up a summary of some main characteristics of the forest.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

__The link: *Access the data directory* is available in the section*Dataset Description Sheets; Additional Information*__. Surface deposit is the layer of loose material that covers rock. The deposit may have been established during the retreat of the glacier at the end of the last glaciation or by other processes associated with erosion and sedimentation. The nature of the loose deposit is evaluated based on the shape of the land, its position on the slope, the texture of the soil, or other indicators. Surface deposit maps make it possible to distinguish the main categories of surface deposits and to know their nature, thickness and distribution on Quebec territory. Based on the interpretation of aerial photographs at a scale of 1/40,000 and control points in the field as part of the ecoforest inventory of southern Quebec, this mapping contributes in particular to the development of ecological forest products. This map covers almost the entire territory of Quebec south of the 52nd parallel. It is distributed by map sheet at a scale of 1/50,000. Surface deposits have a minimum area of 4 ha.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

__The link: *Access the data directory* is available in the section*Dataset Description Sheets; Additional Information*__. The polygonal layer of lidar slope classes expresses the slope of the terrain. The slopes are generated from a digital terrain model (DTM) with a resolution of 10 meters. The latter is the result of an aggregation by bilinear interpolation of lidar NCDs at 1 m. The minimum area of the resulting polygons is 0.2 hectares. Lidar digital slopes are divided into 7 classes. • A - Null from [0 to 3]% • B - Low from] 3 to 8]% • C - Soft from] 8 to 15]% • D - Moderate from] 15 to 30]% • E - Strong from] 15 to 30]% • E - Strong from] 30 to 40]% • B - Low from] 3 to 8]% • C - Soft from] 8 to 15]% • D - Moderate from] 15 to 30]% • E - Strong from] 15 to 30]% • E - Strong from] 30 to 40]% • E - Strong from] 30 to 40]% • F - Steep from] 40 to 40]% • F - Steep from] 40 to ∞ [% • S — Summit entirely surrounded by slopes F This map covers the entire territory of the Southern Quebec Ecoforest Inventory (IEQM) and was developed in order to provide stakeholders with the tools they need when applying for financial assistance from the Forest Management Investment Program (PIAF). __We do not recommend using the information in this layer for detailed analysis. __**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The temporary sample plot is a circular sample unit that covers an area of 400 m2. For each tree, we observe and measure the species, diameter, sunlight, and floor in relation to other trees, as well as defoliation and quality for the stems of deciduous trees and certain pines. In addition, the age and height of three trees are determined. Finally, a survey of the station and the vegetation of the undergrowth is carried out, and the characteristics of the soil are noted. Plot data also includes information about the location of the plots and the sampling plan. These data are acquired as part of the third ecoforest inventory in southern Quebec. They are used in particular to produce forest compilation results used to feed the calculation of forest opportunities in public forests in Quebec. They can also be useful in the development of private forests. The establishment of these plots took place from 1992 to 2005. This database covers almost all of the territory south of the 52nd parallel of Quebec's public and private forest.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

__The link: * Access the data directory* is available in the section*Dataset description sheets; Additional information*__. Ecoforest maps in PDF format are available at a scale of 1/20,000 and cover Quebec territory approximately up to the 52nd parallel. Each map covers an average area of approximately 250 km2 and presents forest information for the territory concerned. Its accuracy is approximately 10 meters. These maps are an image of the current ecoforest map for the corresponding year. __Maps 2021, 2022, 2023 and 2024__ The maps 2021, 2022, 2023, as well as those of 2024 are produced from the up-to-date ecoforest map of the corresponding year. It represents the result of the photo-interpretation of aerial photographs taken during the 4th and 5th ecoforestry inventories of southern Quebec to which were added natural disturbances (fires, epidemics, windfalls, etc.) and forest interventions (harvesting and reforestation) carried out in the public forest following the year in which the picture was taken. According to the maps, data using the forest stand inventory approach (AIPF) is included when available for a complete sheet. Main components: type of vegetation (forest species group, density class, class of density, class of height, age class, etc.) or type of AIPF vegetation (detailed forest species, density (%), height (m), age class, etc.); slope class; class of slope; nature of the terrain (peatlands, height class, age class, etc.); topography (level curves); fragmentation. __2019 and 2020 maps__ The 2019 maps, as well as those of 2020, are produced from up-to-date ecoforest maps of the corresponding year. They represent the result of the photo-interpretation of aerial photographs taken during the 4th and 5th ecoforestry inventories of southern Quebec to which were added natural disturbances (fires, epidemics, windfalls, etc.) and forest interventions (harvesting and reforestation) carried out in the public forest following the year in which the photo-interpretation of aerial photographs from the 4th and 5th ecoforestry inventories of southern Quebec were taken. An update is then carried out taking into account natural disturbances (fires, epidemics, windfalls, etc.) and forest interventions (harvesting and reforestation) carried out in public forests. The information presented corresponds to the current ecoforest map of 2019 or 2020 as the case may be. On each of the maps, the name of the stands is expressed by the group of species. Main components: type of vegetation (forest species, density, height, height, age class, etc.); slope class; nature of the terrain (peatlands, gravel, etc.); hydrography (lakes, rivers, streams, streams, swamps, etc.); transport network and swamps, etc.); transport network and bridges; topography (level curves); fragmentation. __Maps 2015__ The 2015 maps are produced from the photo-interpretation of aerial photographs from the 3rd and 4th ecoforest inventories of southern Quebec. An update is then carried out taking into account natural disturbances (fires, epidemics, windfalls, etc.) and forest interventions (cutting and planting) carried out in public forests. The information presented corresponds to the 2015 updated ecoforest map.

__The link: *Access the data directory* is available in the section*Dataset Description Sheets; Additional Information*__. The Forest Inventory Directorate of the Ministry of Natural Resources and Forests (MRNF) began, in 2021, the production of data that indicates the strength of forest vegetation based on the NBR vegetation index * (Normalized Burn Ratio) *. These data are produced from images from Sentinel-2A/B satellites. The purpose of the layer thus produced is to present a regional portrait, at a given date, of the strength of forest vegetation, at the pixel scale. Before integrating these data into forest planning, it is recommended to plan validation work by photo-interpretation or by means of field visits. It should also be noted that these data are complementary to the other existing data layers (ecoforestry data, fires, harvesting and reforestation, defoliation records from aerial overflights, etc.).**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The temporary sample plot is a circular sample unit that covers an area of 400 m2 (the main unit). For each tree, we observe and measure the species, diameter, and stage in relation to other trees, as well as the defoliation and the quality of the stems of deciduous trees and certain pines. In addition, the age and height of three trees are determined. Finally, a survey of the station is carried out. Plot data also includes information about the location of the plots and the sampling plan. These data are acquired as part of the second forest inventory in southern Quebec. They were used in particular to produce forest compilation results used to feed the calculation of forest opportunities in public forests in Quebec. The establishment of these plots took place between 1980 and 1993. This database covers almost all of the territory south of the 52nd parallel of Quebec's public and private forest.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

__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).**

Local service points are the preferred communication channel for the main local clienteles with the minister's representatives. Staff provide forest services provided by the Department and implement departmental programs. Each management unit office is associated with a territory, and the same office can house two different management units. In addition, due to the size of the territory, a management unit may from time to time have local offices under its responsibility in order to facilitate forest management.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
