__The link: *Access the data directory* is available in the section*Dataset Description Sheets; Additional Information*__. The mapping of vegetation in Northern Quebec is a component of an extensive inventory carried out 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. Vegetation mapping in Northern Quebec provides information on terrestrial ecosystems, both forest and non-forest, such as the type of forest cover, undergrowth vegetation, disturbances, etc. A mapping approach based on remote sensing techniques (satellite images) was used. Ground and air control points contribute to the validation and clarification of the information interpreted. This map is available for the entire territory north of the 53rd parallel, which represents an area of approximately 680,000 km2. This territory is presented on topographical bases 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 link: *Access the data directory* is available in the section*Dataset Description Sheets; Additional Information*__. The LiDAR dendrometric map presents various dendrometric characteristics that are useful in particular in forest planning. It is a product in vector format that is complementary to the results of forest compilations found in the [Original Ecoforest Map and Inventory Results] (https://www.donneesquebec.ca/recherche/dataset/resultats-d-inventaire-et-carte-ecoforestiere) and in the [Results of forest compilations by forel] (https://www.donneesquebec.ca/recherche/dataset/compilations-forestieres-originales-par-forel-methode-k-nn). The geometric entities defined from the LiDAR data are at a finer scale than those in the ecoforest map. The main variables predicted and accessible in the product are as follows: • Usable volume per hectare by species, species group and certain diameter groups • Volume per hectare distributed by product for certain species groups • Basal area and number of stems per hectare for certain species groups for certain species groups • Average usable volume per stem and average diameter for certain species groups • Average usable volume per stem and average diameter for certain species groups The volumes compiled in the LiDAR dendrometric map are variables distinct from the gross volume market on Predicted foot in others results of forest compilations, in the [Cubage Tariff] (https://www.donneesquebec.ca/recherche/dataset/tarif-de-cubage) and for the stems counted in the sample plots of the ecoforestry inventory of southern Quebec, for example in the [Temporary sample plots of the fifth inventory] (https://www.donneesquebec.ca/recherche/dataset/placettes-echantillons-temporaires-du-cinquieme-inventaire). This distinct volume is here qualified as “usable” and it excludes woody material between 9.1 cm in diameter without bark and 9.1 cm with bark. The published literature clarifies the differences between volume variables. This product is available for territories (planning unit, private forest development agency or residual forest territory) with a LiDAR acquisition and affecting the bioclimatic domains of fir to yellow birch, fir to white birch and spruce moss. Product coverage is not complete and will evolve over the years based on the LiDAR acquisition. __Note:__ It is possible to use the [LiDAR dendrometric data preparation tool] (https://www.donneesquebec.ca/recherche/dataset/carte_dendrometrique_lidar/resource/d447ac59-8310-4fad-95f7-7495a3624466) to study one or more sectors at a finer scale than that of the ecoforest map. The [LiDAR dendrometric tool user guide] (https://mffp.gouv.qc.ca/nos-publications/guide-outil-dendrometrique-lidar/) presents the methodology for its application to meet the needs of operational forest harvest planning.**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 ecoforest inventory north of the northern limit of attributable forests is an extensive inventory that was carried out for specific knowledge acquisition needs. It was carried out between 2005 and 2009 as part of the work of the scientific committee responsible for examining the northern limit of attributable forests (Nordic Ecoforest Inventory Program [PIEN]). The data in this inventory comes from a cartography that is based both on the use of archival aerial photographs 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 deposits and drainage) as well as ecodendrometric sample plot data. This data is distributed by map sheet at a scale of 1/250,000. The minimum mapping area is 8 ha for stands and 4 ha for surface deposits.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

This data set includes the locations of all known seabird colonies along the coast of British Columbia, and provides a compilation of the population estimates of seabirds breeding at those colonies since 1980, and historical estimates prior to 1980 for some colonies. It does not include an estimate of the numbers of juvenile birds or non-breeders in the population. The rationale for developing this inventory was the recognized need for a product that could assist with: coastal zone and conservation area planning; emergency response to environmental emergencies and identifying areas of potential interactions between seabirds and anthropogenic activities. In addition, the data used to develop the document provides a baseline to compare with future seabird population estimates in order to measure the impacts of shifts in composition, abundance and/or distribution of prey, and climatic and oceanographic changes. The database is not a substitute for on-site surveys usually required for environmental assessment. Here we present data on the breeding colony population estimates of the 15 species of seabirds (including two storm petrels, three cormorants, one gull and nine alcids) and one shorebird (Black Oystercatcher Haematopus bachmani) that breed on the coast of British Columbia. Over 5.5 million colonial birds are currently estimated to nest at 627 sites, based on surveys primarily conducted in the 1980’s. Five species (Cassin's Auklets Ptychoramphus aleuticus, Fork-tailed Storm-petrels Oceanodroma furcata, Leach's Storm-petrels Oceanodroma leucorhoa, Rhinoceros Auklets Cerorhinca monocerata, and Ancient Murrelets Synthliboramphus antiquus) comprise the vast majority of that population, although Glaucous-winged Gulls (Larus glaucescens) and Pigeon Guillemots (Cepphus columba) nest at the most sites. Marbled Murrelets (Brachyramphus marmoratus), which nest on the mossy limbs of mature and old-growth trees within the coastal forests, are not included in this database, due to their dispersed nesting habit. The population estimates presented in this database are compiled from the results of several surveys. Many of the seabird breeding colonies in British Columbia have been known for more than 50 years, but because of the remoteness of the sites, visits to them have been rare. The majority of the data are the results of a comprehensive inventory of colonial nesting seabirds along the British Columbia coastline conducted between 1980 and 1989 by the Canadian Wildlife Service of Environment and Climate Change Canada. The goal of that program was to establish baseline estimates of breeding seabird populations in BC using standardized survey techniques to allow future comparisons and monitoring of those populations. A few colonies on small remote islands were not visited during that survey. Therefore, for some colonies the most current population estimates are from the first complete survey of the BC coastline, carried out by the Royal British Columbia Museum in the mid 1970’s. That survey identified colony sites and provided rough assessments of the population sizes of breeding seabirds. Since 1989, surveys have been conducted on some alcid, cormorant and gull colonies along the BC coast, and results have been included in the dataset (data entry ongoing). As well as data from Canadian Wildlife Service surveys, we have attempted to obtain recent data from all other sources including Parks Canada, the Ministry of Forests, Lands, Natural Resource Operations and Rural Development, the Bamfield Marine Station and the Laskeek Bay Conservation Society. Since 2000, inventories of nesting Black Oystercatchers have been conducted in some regions of the coast by Parks Canada and partners (Gulf Islands National Park Reserve, Pacific Rim National Park Reserve, and Gwaii Haanas National Park Reserve) and results have been included in the dataset (data entry ongoing). A long time series of nesting Black Oystercatcher data collected by Laskeek Bay Conservation Society in the Laskeek Bay area of the East Coast of Moresby Island has also been included in this dataset.

From 1986 to 2000, a major ecological inventory program was carried out in the forests of southern Quebec in order to describe the diversity of forest ecosystems. In total, 28,425 ecological observation points (POE) were established on a territory covering 760,000 km2, located between 45° and 53° N latitude and 57° and 80° W longitude. The POE is a circular sampling unit that covers an area of 400 m². It collects data on the characteristics of forest stand (composition, structure), soil (texture, deposit, drainage), and topography, as well as location information. The coverage of each plant species in the plot is estimated visually. A detailed description of a soil profile is available in approximately 35% of POEs. The ecological classification elements of POEs (groups of indicator species, forest types, potential vegetation, ecological types, etc.) are determined using computerized identification keys using data on vegetation and the physical environment. The criteria used for this ecological classification are those presented in the guides for the recognition of ecological types. The levels of the ecological classification system of the territory are also determined for each POE.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The canopy is defined by the projection on the ground of the tops (crown) of trees (including leaves, branches, and trunks), which is visible from the sky. Any vegetation with a height greater than 2 m was taken into account. The mapping of the canopy was carried out using deep learning methods, based on variables (resolution of 1 m) calculated from raw airborne lidar data from 2010 to 2020. It covers the six census metropolitan areas (CMAs) of Quebec: Gatineau, Montreal, Quebec, Saguenay, Sherbrooke and Trois-Rivières.
