__The link: *Access the data directory* is available in the section*Dataset Description Sheets; Additional Information*__.The third edition of the [*Small forest flora of Quebec (MRNF, 2023) *] (https://boutique.publicationsduquebec.gouv.qc.ca/recherche/Petite%20flore%20foresti%C3%A8re) presents the distribution maps of 298 species of trees, shrubs, herbaceous plants, bryophytes and lichens that grow in Quebec forests. The AIRES_REPARTITION_PFFQ database is the product resulting from the vectorization of each of the distribution areas presented in Little Flora. It thus allows the consultation of these areas in a geographic information system.The ranges are grouped into a single feature class where the main range of each species is bounded by one or more polygons. The location of isolated populations, located outside the main range of a species, is indicated very generally by circles 30 km in diameter.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

This theme presents observations of invasive exotic species (IAS)transmitted and validated using the Sentinelle tool, an EEE detection system.An invasive exotic species is a plant, animal or microorganism (virus,bacteria or fungi) that are introduced outside of their natural range. Sonestablishment or its spread may pose a threat to the environment,the economy or society. The species listed are species of fauna and floraconcerning (or potentially worrying) for Quebec's biodiversity. Ellesinclude EEE present in Quebec and EEE not listed in Quebec atmonitor.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The “Agro-Pedological Atlas of Quebec” is a dataset that shows the characteristics, the fertility, the quality of the water regime, the vulnerability to degradation and the potential of the agricultural soils and land in the Monteregian region of the province of Quebec.

The Quebec Ecological Reference Framework (CERQ) is a tool for mapping and ecological classification of Quebec territory. It apprehends the territory from the general to the particular, in a hierarchical system of interlocking levels of perception. This layer of information was produced as part of the ecological knowledge project of the Ministry of Sustainable Development, Environment and the Fight against Climate Change (MDDELCC). **This third party metadata element was translated using an automated translation tool (Amazon Translate).**

Important noteThe AQRéseau+ product, distributed in the Adresses Québec range, is evolving and is now available under the name of [Quebec Land Transport Repository (RQTT)] (https://www.donneesquebec.ca/recherche/dataset/referentiel-quebecois-du-transport-terrestre). Consult the product sheet for up-to-date data. The web service associated with AQRéseau+ remains available in this sheet until the RQTT web service is online.The transition of Adresses Québec products will continue until the end of 2026. For more information, see the [Frequently Asked Questions (FAQ)] document (https://diffusion.mern.gouv.qc.ca/diffusion/RGQ/Vectoriel/Documentation/AdressesQuebec/FAQ_Fin_diffusion_AQ.pdf).Adresses Quebec is a road geobase that covers all of Quebec. It offers a complete road network including official names, addresses by slices and points, information for route management, postal codes (MOs) and a cartographic context.The user guide is available at ** [next link] (https://diffusion.mern.gouv.qc.ca/diffusion/RGQ/Vectoriel/Documentation/AdressesQuebec/guide_utilisateurs.pdf) **.For more information on the full range of products, refer to the ** [directory of web services and geographic data] (https://mrnf.gouv.qc.ca/ministere/cartes-information-geographique/repertoire-services-web-donnees-geographiques/) ** of the MRNF.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The Shorezone Biobanding Polygons are an area representation of the various types of biota (flora and fauna) and their distribution, or lack thereof, found in the shoreunit.

The Shorezone Biobanding Lines are a linear representation of the various types of biota (flora and fauna) and their distribution, or lack thereof, found in the shoreunit.

The Copper Redhorse (Moxostoma hubbsi) is the only fish whose distribution is exclusively restricted to Quebec. This range is restricted even further to the St. Lawrence River and some of its tributaries.This layer represents the Copper Redhorse critical habitat defined by the analysis of available knowledge and a scientific advice.PurposeThe Copper Redhorse population is in decline due to several threats like habitat degradation, construction of dams, contaminants, exotic or introduced species, recreational activities, commercial fishery, and low water levels. Furthermore, certain biological characteristics of the Copper Redhorse contribute to its vulnerability. The Copper Redhorse population was officialy listed as endangered in Schedule I of the Species at Risk Act in December 2007.Additional InformationCritical habitat for the Copper Redhorse has been identified to the extent possible, based on the best available information. Two workshops held in 2009 and 2010 by Fisheries and Oceans Canada and the Ministère des Ressources Naturelles et de la Faune du Québec, allowed to review the information and take note of the new data to identify habitat use by the Copper Redhorse in the St. Lawrence and Richelieu rivers and later in the Rivière des Prairies and Rivière des Milles Îles. Adult feeding habitat in the St. Lawrence River between Lake Saint-Louis and Lake Saint-Pierre, was identified using modeling based on the telemetric monitoring of habitat use and on twelve habitat variables (for example: depth, current velocity, vegetation density). Also, recent telemetry and historic data confirmed the use of the lower stretches of the Rivière des Prairies and Rivière des Mille Îles. Critical adult feeding habitat is consequently identified as habitat in the fluvial reach between Montreal and Sorel presenting favorable characteristics for the copper redhorse, used in the model.DFO. 2012.

This theme represents the limit of the Quebec territory of the Agreement on Sustainable Water Resources of the Great Lakes and St. Lawrence River Basin. It was generated from the grouping of watersheds at a cartographic scale of 1:20,000.

To assess the current distribution of kelp beds and other macroalgae in Nova Scotia and Southwest New Brunswick, subtidal drop camera surveys were performed from 2022-2023 at 140 sites. For each site, a GoPro HERO 10 camera was towed along a deep (7-12m) and shallow (3-5m) depth contour until 20 images were acquired per depth. Where possible, species were identified from photos, with particular care given to kelps (defined here as orders Laminariales and Tilopteridales) and fucoids (order Fucales). Crust-forming algae was not counted. Percent cover was calculated using a 10x10 point grid overlaid on each image and recording the dominant cover type at each point. The depth (in meters) of each photo after correcting for tide height ranged from ~0.5m to ~12m. Depths were corrected to chart datum (lowest astronomical tide) using tide predictions from the nearest tide station, taken from tides.gc.ca. Sampling was performed between July and October.
