The ecoforestry maps in the third inventory cover almost the entire territory south of the 52nd parallel. Each file covers an area of approximately 250 km2. These digital maps illustrate forest stands. They were prepared from photo-interpretation of aerial photos at a scale of 1/15,000. Main components: • contour of forest stands • subclusters of species in all stands; • vegetation type (forest species, density, height and stage of development, origin) • age class • disturbance; • nature of terrain (peatlands, gravel, etc.); • territorial subdivisions; • hydrography; • network of transport and bridges; • slope classes; • defoliation class; • surface deposition; • drainage class; • ecological type. **This third party metadata element was translated using an automated translation tool (Amazon Translate).**

Forestry infrastructure mapping corresponds to the forest area from which trees have been removed for infrastructure purposes, for example, for the establishment of power lines, agricultural areas or hydroelectric reservoirs, or for separate purposes of forest harvesting. The areas contained in this mapping date back to 2003. This mapping covers almost all of the territory south of the 52nd parallel of Quebec's public and private forest. The information constituting it comes from different sources. For example, the Quebec Topographic Database is used for hydroelectric reservoir launch mapping. The minimum mapping area is 0.1 ha. **This third party metadata element was translated using an automated translation tool (Amazon Translate).**

Harvest and reforestation mapping is produced as part of the Southern Quebec Ecoforestry Inventory in order to maintain an up-to-date portrait of the forest. Several forestry operations stakeholders are involved in maintaining this forest portrait, including the Regional Operations Sector of the Ministry of Forests, Wildlife and Parks, private forest development agencies and large landowners. This mapping contains information on forest interventions carried out in the territory (e.g., harvesting, thinning, reforestation) and the year of work. The period of work begins at the beginning of the 20th century (when information is available) until today. This mapping covers the commercial territory of Quebec's public and private forest. The minimum mapping area is 0.1 ha. Note: When there is more than one intervention in the same territory in the same year, priority is given to sustainably modifying forest cover (e.g. planting). To access all interventions in the same territory (in public forest only), please consult the Technical and Financial Activity Reports (RATF) distributed by the Department'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 cubage tariff is presented in the form of a table. It gives, in essence, the gross merchant volume of a stem based on its diameter at chest height (DHH) and height. These are local rates, that is, the height used in the general tariff equation is predicted by height-DHP relationships developed per sample unit. The cubage rate is produced for the main forest species in southern Quebec and covers almost all of the territory south of the 52nd parallel. **This third party metadata element was translated using an automated translation tool (Amazon Translate).**

This dataset contains the polygons delineating the timber of the Montreal agglomeration. Wood boundaries and composition are the result of an analysis of aerial photos and/or field visits and/or specific ecological studies. These are constantly updated according to the advancement of local knowledge. Some plant communities and their boundaries may therefore be imprecise. **This third party metadata element was translated using an automated translation tool (Amazon Translate).**

Northern Quebec vegetation mapping is a component of an extensive inventory conducted to meet knowledge acquisition needs as part of the economic, social and environmental development project “Plan Nord”. This inventory was carried out between 2010 and 2013. Northern Quebec vegetation mapping provides information on terrestrial ecosystems, both forest and non-forest, such as forest cover type, undergrowth vegetation, disturbance, etc. A mapping approach based on remote sensing techniques (satellite images) was used. Land and air control points help validate and clarify interpreted information. This mapping is available for the entire territory north of the 53rd parallel, representing an area of approximately 680,000 km2. This territory is presented on a topographical basis at a scale of 1/250 000. The minimum mapping area is 16 ha for vegetation and 3 ha for wetlands. **This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The ecoforest inventory north of the northern boundary of attributable forests is an extensive inventory that has been conducted for specific knowledge acquisition needs. It was carried out between 2005 and 2009 as part of the work of the Scientific Committee on the Northern Boundary of Attributable Forests (Northern Ecoforestry Inventory Programme (NAIP)). The data in this inventory is derived from a mapping that relies on both the use of aerial photographs of archives interpreted in three dimensions on the screen and on the analysis of satellite images. This dataset covers the territory between the 50th and 53rd parallel and covers an area of 242,000 km2. It includes forest and ecological mapping data (vegetation, surface deposition and drainage) as well as ecodendrometric sample plot data. These data are disseminated by a map sheet at a scale of 1/250,000. The minimum mapping area is 8 ha for stands and 4 ha for surface deposition. **This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The slope classes express the inclination of land where most of the forest stand is located. The slope classes are generated from a numerical model grouping in six classes the terrain slopes: + 0 -3% zero + Low of 4-8% + Soft of 9-15% + Moderate of 16-30% + Strong 31-40% + Steep 41% or more This mapping covers almost all of Quebec's territory south of the 52nd parallel. It is distributed by map sheet at a scale of 1/250,000. The slope classes have a minimum area of 0.5 ha. __Note:__ The numerical terrain model is prepared from the level and elevation point curves derived from the topographic map at the scale of 1/20,000 and 1/50,000 from the Quebec Topographic Database (BDTQ). __Old Name:__ Numerical Slope Classes **This third party metadata element was translated using an automated translation tool (Amazon Translate).**

NFIS Project Office. This Web services are for forest change products that represents the first wall-to-wall characterization of wildfire and harvest in Canada at a spatial resolution commensurate with human impacts. The information outcomes represents 25 years of stand replacing change in Canada's forests derived from a single consistent spatially-explicit data source and derived in a fully automated manner.

Ecoforestry maps in PDF format are available at a scale of 1/20,000 and cover Quebec territory approximately to the 52nd parallel. Each map covers an average area of about 250 km2 and presents the forest information of the territory concerned. Its accuracy is approximately 10 meters. __Maps 201The 2015 maps are produced from photo-interpretation of aerial photographs from the 3rd and 4th Ecoforestry Inventory of Southern Quebec. An update is then carried out taking into account natural disturbances (fires, epidemics, woodshablis, etc.) and forest interventions (cuts and plantations) carried out in public forests. The information presented corresponds to the updated ecoforestry map of 2015. __Maps 2019 and 2020__ The 2019 maps, as well as those of 2020, are produced from photo-interpretation of aerial photographs from the 4th and 5th Ecoforestry Inventory of Southern Quebec. An update is then carried out taking into account natural disturbances (fires, epidemics, forest forest, etc.) and forestry interventions (harvesting and reforestation) carried out in public forests. The information presented corresponds to the current ecoforestry map of 2019 or 2020 as applicable. On each of the maps, the name of stands is expressed by the grouping of species. Main components: vegetation type (forest species, density, height, age class, etc.); slope class; nature of terrain (peatlands, gravel, etc.); hydrography (lakes, rivers, streams, swamps, etc.); transportation system and bridges; topography (level curves); fragmentation.
