The **portrait of forest cover in Québec** 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*__. **The results of compilations by forel** are one of the deliverables of the ecoforest inventory in southern Quebec. These results are used to produce forest compilations by stand associated with the original ecoforest map. The forel corresponds to a forest pixel with a resolution of 20 meters by 20 meters. These results are presented in the form of matrix mapping (image in raster format) to assess the variability of the various dendrometric characteristics within the same forest stand. Here is the list of variables presented in this map: gross market volume per hectare, basal area per hectare and number of stems per hectare. These results are intended to provide small-scale information that can, among other things, support the planning of forest operations. They cover ecoforest stands 7 m or more in height. For commercial stems, a separate matrix file is produced for each of the three variables and each of the species, attribution groups, species types and for the total all species. For saplings (stems of 9 cm or less in diameter), only results for basal area and the number of stems per hectare for species types and for the total of all species are produced. The information contained in this map is an image of the forest in the year the aerial photograph was taken. The results of this forest compilation method will eventually cover most of the territory south of the 52nd parallel. When achieved, the results are disseminated by planning unit (AU) for the territories produced under the fourth inventory and by ecological planning unit (UPE) for the territories produced as part of the fifth inventory. __ ⚠️ Notes: __ Consult the [original ecoforest map and current inventory results] ] (https://www.donneesquebec.ca/recherche/dataset/resultats-d-inventaire-et-carte-ecoforestiere) for the results of forest compilations by population, also available on Data Quebec. **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*__. **Slope classes** express the slope of the terrain in a relatively homogeneous area with a minimum area of 0.5 ha. They are generated from a numerical model that groups terrain slopes into six classes: + 0-3% zero + Low by 4-8% + 9-15% soft + Moderate by 16-30% + 31-40% strong + Steep by 41% or more These data cover almost all of Quebec south of the 52nd parallel. This map is presented in two groups: grouping at the provincial level and grouping at the scale of 1/250,000. Each grouping represents an assembly of sheets produced on a scale of 1/20,000. The datasets were originally produced in 2005 and then updated in 2006. In 2010, they were enhanced with slope information for the northernmost part. No updates have been made since then. __For more information, please refer to the document: [Products presenting the concept of slope] (https://diffusion.mffp.gouv.qc.ca/Diffusion/DonneeGratuite/Foret/DONNEES_FOR_ECO_SUD/Classes_pente/01-Documentation/Produits_presentant_la_notion_de_pente.pdf) __ __ ⚠️ Notes: __ The numerical terrain model is prepared from the level curves and altitude points that come from the topographic map at a scale of 1/20,000 and 1/50,000 from the Quebec Topographic Database (BDTQ).

__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 ecoforestry 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 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 that__ 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 way (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 link: * Access the data directory* is available in the section*Dataset description sheets; Additional information*__. The forest maps from the first inventory are available at a scale of 1/20,000. They cover almost all of the territory south of the 52nd parallel. Each file covers an area of approximately 250 km2. These digital maps correspond to the black and white paper maps with a dimension of 125 cm X 75 cm that have been digitized and georeferenced. They illustrate forest stands. They were prepared from the photo-interpretation of aerial photos on a scale of 1/15,000. Main components: •outline of forest stands; • type of vegetation (forest species, density, height and stage of development, origin); • disturbances; • nature of the land (peatlands, gravel, etc.); • territorial subdivisions; • hydrography (lakes, rivers, streams, swamps, etc.); • transport network and bridges; • topography (level curves). The units of measurement shown on the maps in the first inventory are those of the English imperial system of measurement. **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 Directorate of Forest Inventories (DIF) carries out assessments of tree biomass and their carbon content at the scale of ecoforest stands to deepen knowledge on the contribution of forests in the global carbon cycle. This information can be useful in the context of climate change to document the mitigating role played by forests. The resulting product, a database containing a single table entitled “BIOMASSE_CARBONE_PEE_ORI_PROV”, shows the biomass and carbon values of living trees above ground for all productive ecoforest stands 7 m or more in height. The exploitation of the database requires the data from [the original ecoforest map] (https://www.donneesquebec.ca/recherche/dataset/resultats-d-inventaire-et-carte-ecoforestiere) and the establishment of a connection with the information of the polygonal entity class of settlements. The database includes biomass variables converted to carbon stocks, detailing the biomass of wood, bark, branches, and foliage. For a thorough understanding, you can consult the Read Me associated with this product and the publication [“Biomass and carbon forests in southern Quebec - Method and use”] (https://mrnf.gouv.qc.ca/nos-publications/biomasse-carbone-forestiers-quebec-meridional/) (MRNF, 2023) which offers additional methodological information. **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 layer of **ecological planning units (UPE) ** constitutes the territorial base at the base of the ecoforest inventory process in southern Quebec (IEQM). It was created and then integrated as part of the current inventory (fifth IEQM). It integrates concepts that are both administrative (forest region) and ecological (ecological region). More precisely, the division is done on an ecological basis within each of the forest regions. It is on this basis that the activities of the IEQM are planned. Each of the layers included in the IEQM monitoring datasets reports on what has been achieved as part of the current inventory. We are talking here about aerial photography, mapping, terrestrial sampling of temporary sample plots, and compilation activities. Each year, new territories are added to each layer to reflect the progress of the work. **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. __2021, 2022, 2023 and 2024 cards__ The 2021, 2022, 2023 maps, as well as those of 2024, are produced from the current 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 grouping, density class, height class, age class, etc.) or type of AIPF vegetation (detailed forest species, density (%), height (m), age class, etc.); slope class; type of terrain; nature of the terrain (peatlands, height class, age class, etc.) or type of AIPF vegetation (detailed forest species, density (%), height (m), age class, etc.); slope class; nature of the terrain (peatlands, gravel, etc.); hydrography (lakes, rivers, streams, swamps, etc.); transport network and bridges; 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, age class, etc.); slope class; type of terrain (peatlands, gravel, etc.); hydrography (lakes, rivers, streams, 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.
