__The link: *Access the data directory* is available in the section*Dataset Description Sheets; Additional Information*__. The original ecoforest map of the third inventory is made from aerial photographs as well as several other products to inform the photointerpreter (forest interventions, information concerning natural disturbances, data from previous inventories, etc.). This map shows the various forest and ecological characteristics of the forest territory and corresponds to the forest profile up to the year in which the aerial photograph was taken. To learn more about ecoforest stratification parameters, simply consult Chapter 3 of the document [*Ecoforest Mapping Standards — Third Ecoforest Inventory (MRNF, 2009) *] (https://mrnf.gouv.qc.ca/documents/forets/inventaire/norme-cartographie-ecoforestiere.pdf). __Note that__ the original ecoforest map of the third inventory has been complete since 2003 and that no new cartographic information has been added since then. Note, however, that improvements were made to the dataset format in 2025.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

This data set contains the polygons delimiting the woods of the agglomeration of Montreal. The boundaries of the woods and their composition are the result of an analysis of aerial photos and/or of field visits and/or of particular ecological studies. These are constantly updated in accordance with the advancement of knowledge in the community. Some plant communities and their limits may therefore be imprecise.**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 have been produced at a scale of 1/10,000 since 2025 (previously, they were distributed at a scale of 1/20,000) and illustrate forest information for Quebec territory up to approximately the 52nd parallel. They offer an up-to-date image of the ecoforest map for the year of production. The maps represent the result of the photo-interpretation of aerial photographs taken during the most recent ecoforestry inventory of southern Quebec to which were added natural disturbances (fires, epidemics, windfalls, etc.) and forest interventions (harvesting, thinning and reforestation) carried out in the public forest following the year in which they were taken. Vegetation information specific to each stand is expressed in detailed species (AIPF) when information is available for a complete sheet. Otherwise, vegetation is expressed as a group of species. Each map at a scale of **1/10,000** covers an average area of approximately **62.5 km²** and presents forest information for the target territory. Its accuracy is approximately ± 5 m. Each map at a scale of **1/20,000** covers an average area of approximately **250 km²** and presents forest information for the target territory. Its accuracy is approximately ± 10 m. ## Descriptions of maps and components ### 2025 maps: + Scale (1/10,000); + Replacing the BDTQ level curves with those from the lidar; + Characterization of vegetation by detailed species (AIPF) or by grouping of species, depending on the availability of information; + Maps based on up-to-date ecoforest maps from the 4th and 5th inventories. ### Maps 2021 to 2024: + Scale (1/20,000); + Characterization of vegetation by detailed species (AIPF) or by grouping of species, depending on the availability of information; + Maps based on up-to-date ecoforest maps from the 4th and 5th inventories. ### 2019 and 2020 maps: + Scale (1/20,000); + Characterization of vegetation by grouping of species; + Maps based on up-to-date ecoforest maps from the 4th and 5th inventories. ### 2015 maps: + Scale (1/20,000); + Characterization of vegetation by grouping of species; + Maps based on up-to-date ecoforest maps from the 3rd and 4th inventories. ## ⚠️ Notes: + Forest codes vary depending on the inventory; **consult the legend** of the map. + The maps are **georeferenced** and optimized for printing. + **AIPF**: The AIPF (**forest stand inventory approach**) is a method used in Quebec for ecoforest stratification to classify forests according to their populations and including updates compared to previous inventories.**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*__. Formerly, forest maps were produced by the Land Survey Department of the Ministry of Lands and Forests. Some of these maps dating **from 1924 to 1946** still exist and are treasured at the National Archives of Quebec. The information they contain makes it possible to locate and characterize forest areas in certain regions of Quebec. Color codes were then assigned for each of the following classes: young forests, old forests, burned, logged, rocky, savannas, and colonization. **These historical forest maps are available in two digital formats (PDF and TIFF) . ** **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 **up-to-date ecoforest map (formerly “with disturbances”) ** is the result of the interpretation of aerial photographs and control points in the field as part of the ecoforest inventory of southern Quebec. This mapping presents the various forest and ecological characteristics of the forest territory and corresponds to the portrait of the forest up to the year the aerial photograph was taken (mapping cycle of about 10 years). Next, the outlines and nature of recent disturbances (forest interventions, fires and other disturbances) are then integrated annually. The fifth mapping cycle has been under way since 2015. This map covers almost all of the territory south of the 52nd parallel of Quebec's public and private forest. It is distributed by map sheet at a scale of 1/250,000. The minimum mapping area is 4 ha for stands and 0.1 ha for disturbances. __ ⚠️ 1) Note that__ the disturbance maps used to update the updated ecoforest map are also distributed separately on Data Quebec. Here is the list of these maps: + ** [Forest fires] (https://www.donneesquebec.ca/recherche/dataset/feux-de-foret) ** + ** [Harvesting and other silvicultural interventions] (https://www.donneesquebec.ca/recherche/dataset/recolte-et-reboisement) ** + ** [Epidemics, windfalls and ice storms] (https://www.donneesquebec.ca/recherche/dataset/epidemies-chablis-et-verglas) ** + ** [Forest Infrastructure] (https://www.donneesquebec.ca/recherche/dataset/infrastructures-en-milieu-forestier) ** __ ⚠️ 2) Note that__ disturbances are prioritized according to the nature of the layer and respect for the chronology of events. Only the last original or partial disturbance is kept in the updated ecoforest map. You should refer to the annual update layers, listed in __Note 1__, to access the full history of disturbances.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
