Polygon geometry for an invasive species observation. The polygon represents the area of the observation. An observation of an invasive species can be either positive or negative. Positive indicates the species was present at the time of the observation. Negative indicates the species was not present at the time of the observation. Dataset currently only includes plant species.

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).**

Aquatic invasive species pose economic and ecological threats to Canada's coastal waters. In response, Fisheries and Oceans Canada (DFO) has established monitoring programs to detect and track the spread of aquatic invasive species, including European Green Crab, in Canadian waters. Fukui traps have been deployed annually at both new and long-term monitoring locations throughout coastal British Columbia.

This map, created in 2002 using ArcGIS, describes the number of animal and plant species that are at risk in Alberta. 'Species at risk' is a term used by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) that includes the following categories of plants and animals:Extirpated species - no longer in the wild in Canada.Endangered species - species facing imminent extirpation or extinction.Threatened species - likely to become an endangered species if nothing is done to reverse factors leading to its extirpation or extinction.Species of special concern - species that may become threatened or endangered due to biological characteristics or identified threats.

Survey data depicting the presence of the endangered Rocky Mountain Ridged Mussel (Gonidea angulata) from 2008-2011. Surveys were conducted by different researchers at different locations.

Fisheries Information Summary System (FISS) layer of Historic (pre 2001) Fish Distribution Points of BC Streams. Points represent site locations where a fish species is rearing, spawning or observed or where a point is located at the mouth of a stream it indicates the presence of a fish species somewhere in the stream as a whole. Georeferenced to the stream centreline network layer of the 1:50,000 scale BC Watershed Atlas.

This dataset shows the known and previously reported location of rare plants and animals in Yukon Territory as mapped by the Yukon Conservation Data Centre. The Yukon Conservation Data Centre follows NatureServe methodology that depicts Element Occurrences (an area of land and/or water in which a species is or was present)(EO) as polygons. These polygons include locational uncertainty. The locational uncertainty incorporates inaccuracies that can be associated with the collection of location information, such as inaccurate GPSs or vague locational descriptions. Data are mapped at 1:50,000 or larger scale. A user manual describing the data can be found at [https://mapservices.gov.yk.ca/geoyukon/Understanding_Yukon_Conservation_Data_Centre_Data.pdf](https://mapservices.gov.yk.ca/geoyukon/Understanding_Yukon_Conservation_Data_Centre_Data.pdf) . For detailed information about particular element occurrences, contact the Yukon Conservation Data Centre at [yukoncdc@yukon.ca](mailto:yukoncdc@yukon.ca) or 867-667-3684.It is very important to note that the absence of mapped locations in an area of interest does not necessarily mean that there are no species of conservation concern present; only that there are none currently recorded in the database. A detailed assessment of the site conducted during the appropriate season by qualified biologists is the only way to confirm presence or absence of a species of conservation concern.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/geoyukon) .

The European Green Crab (EGC) is a high-risk global invader that can devastate coastal marine ecosystems by displacing native species, degrading and disturbing native habitats (including eelgrass), and altering food webs. EGC has recently been detected in the Canadian portion of the Salish Sea. As EGC continue to establish in the region, identifying locations on which to focus limited monitoring resources is an ongoing problem given the vast amount of coastal habitat that could be occupied by the species. A variety of methods can be used to identify highly suitable habitats for EGC at a range of spatial scales. However, none have been evaluated in the context of informing EGC management, nor for the Canadian portion of the Salish Sea. Here we evaluate five individual methods developed to assess habitat suitability for EGC (i.e., MaxEnt, stochastic gradient boosted linear and logistic regression models, a rapid site selection tool, and a qualitative site assessment and ranking tool) and five derived models generated by multiplying the outputs of these individual models. Each model relied on slightly different environmental and habitat input variables affecting EGC invasion success. Thus, rather than identifying a single preferred model, we used a multi-model ensemble approach to identify sites that are expected to be most suitable for the species. The ensemble approach likely increases predictive power by including both environmental and habitat characteristics when identifying priority sites for early detection/monitoring for EGC in the Canadian waters of the Salish Sea. Finally, we describe how the models evaluated here, alone or in combination, could be used to identify additional sites either within the Salish Sea or into new areas.This dataset contains predicted habitat suitability from five models for European Green Crab at beaches in the Salish Sea (British Columbia, Pacific Region).

A spatial representation of the general distribution of wild mountain sheep (bighorn and thinhorn sheep) in British Columbia. Populations that extend into neighbouring provinces and states are also included. The distribution polygons are divided by species into bighorn and thinhorn sheep.

## #DescriptionThis database contains the coordinates of observations of fish and invertebrates, which are exotic and invasive, known by the Ministry of the Environment, the Fight against Climate Change, Wildlife and Parks (MELCCFP) in Quebec as of April 2026.An aquatic invasive species is a plant, animal, or microorganism (virus, bacteria, or fungus) that is introduced outside of its natural range, colonizes new sites or regions at a rapid rate, and can form dominant populations. Its establishment or spread can pose a threat to the environment, economy, or society.## #Les observations come from a variety of sources such as:* scientific sampling carried out by the MELCCFP and by other governmental or non-profit organizations;* mentions of citizens who contacted MELCCFP customer service directly or using tools such as Sentinelle and iNaturalist;* accidental catches by commercial fishermen who are members of the Saint Lawrence Network for the Early Detection of Exotic Aquatic Invasive Species.For more information on the control of aquatic invasive species, introduction factors, or prevention methods, consult the following web page: [Management of exotic invasive animal species] (https://www.quebec.ca/agriculture-environnement-et-ressources-naturelles/faune/gestion-faune-habitats-fauniques/gestion-especes-exotiques-envahissantes-animales).To help you identify the various species of freshwater fish in Quebec (native and invasive), use the iPêche mobile application (available [here] (https://www.quebec.ca/tourisme-et-loisirs/activites-sportives-et-de-plein-air/peche-sportive/identifier-poisson-ipeche)), which is free and developed by the Government of Quebec. This application allows voluntary reporting of catches for wildlife research purposes.## #Mises on guard* __Please consult the PDF document for the list of acronyms and references used in the “Invasive exotic aquatic fauna in Quebec” database . __* Data is not exhaustive.
