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).**

As part of the provincial LiDAR sensor data acquisition project, a topographic humidity index was produced from the aerial Light Detection and Ranging (LiDAR) digital terrain model. The matrix layers produced thus provide information on the potential for water accumulation in the territory depending on the slope and accumulation at a given pixel. **This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The temporary sample plot is a circular sampling unit that covers an area of 400 m2. It observes and measures for each tree the species, diameter, sunshine, stage relative to other trees, as well as defoliation and quality for stems of deciduous trees and some pine trees. In addition, the age and height of three trees are determined. Finally, a survey of the site and vegetation of the undergrowth is carried out, and the characteristics of the soil are noted. Pplot data also includes information about the location of plots and the sampling plan. These data are acquired as part of the third ecoforestry inventory of southern Quebec. They are used in particular to produce forest compilation results used to feed the calculation of forest opportunities in public forest in Quebec. They can also be useful for the development of private forest. These plots were implemented 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).**

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).**

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 cards correspond to black and white paper cards with a dimension of 125 cm X 75 cm that have been digitized and georeferenced. They 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; • vegetation type (forest species, density, height and stage of development, origin); • disturbance; • nature of the terrain (peatlands, gravels, etc.); • territorial subdivisions; • hydrography (lakes, rivers, streams, swamps, etc.); • transportation and bridges; • topography (level curves). The units of measurement shown on the maps in the first inventory are those of the English Imperial Measurement System. **This third party metadata element was translated using an automated translation tool (Amazon Translate).**

Forest maps in the second 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.

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).**
