Number of Species at Risk
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.
Carmine Shiner Conservation Physiology
Results from temperature preference experiments demonstrated that individual personality was consistent and repeatability. Individual preferred and maximum avoidance temperatures were significantly reduced in hypoxia compared to normoxia. Standard metabolic rate increased with temperature and body mass. Patterns of projected habitat change suggest the spatial extent of the current distribution of Carmine shiner would shift north with global warming. The understanding of habitat requirements and responses to climate will aid management and recovery efforts for this threatened species.Cite this dataset as: Enders, Eva.

Invasive Species Observations
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.
Sentinel - Invasive exotic 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).**
Rocky Mountain Ridged Mussel Distribution Survey Data
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.
Pelagic Shark Satellite Tag data - White Shark
The white shark (Carcharodon carcharias), is a species found in Atlantic Canadian waters which is encountered in commercial and recreational fisheries. Pop-up Satellite Archival Tags (PSAT) from Wildlife Computers were applied to white sharks from 2016 to the present to collect data on depth (pressure), temperature and ambient light level (for position estimation). Deployments were conducted in Canada and the United States (Cape Cod and South Carolina) on scientific charters, typically in summer. Tag models deployed included: Mk10 (N=1), and MiniPAT (N=29) and 22 of 27 tags reported with 3 still at liberty. One individual shark returned to the location of tagging 1 year later and the physical tag was recovered. Another tag was recovered 5 years after deployment. White sharks tagged ranged in size from 259 cm to 459 cm Total Length (curved) estimated; 15 were female, 13 were male, and 2 were of unknown sex. Time at liberty ranged from 48 – 377 days and to date, only 3 tags remained on the shark for the programmed duration. Tagging of white sharks is an ongoing study and data will be updated here when it becomes available. Raw data transmitted from the PSAT’s after release was processed through Wildlife Computers software (GPE3) to get summary files, assuming a maximum swimming speed of 2m/s, NOAA OI SST V2 High Resolution data set for SST reference and ETOPO1-Bedrock dataset for bathymetry reference. The maximum likelihood position estimates are available in .csv and .kmz format and depth and temperature profiles are also in .csv format. Other tag outputs as well as metadata from the deployments can be obtained upon request from: warren.joyce@dfo-mpo.gc.ca or heather.bowlby@dfo-mpo.gc.ca.
BC Historical Fish Distribution - Points (50,000)
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.
National Aquatic Invasive Species (AIS) Risk Assessment for Zebra (Dreissena polymorpha) and Quagga (Dreissena rostriformis bugensis) Mussels
Zebra Mussel (Dreissena polymorpha) and Quagga Mussel (Dreissena rostriformis bugensis) have a long history of invasion in European and North American freshwater ecosystems, with significant ecological and economic impacts. An ecological risk assessment for these two invasive species for freshwater ecosystems in Canada was completed in April 2022 with the aim to provide science-based guidance to inform management decisions and actions. These include early detection, response planning, and/or regulatory and policy measures aimed at mitigating the potential spread and risk posed by Zebra and Quagga Mussels to Canadian freshwater ecosystems (DFO 2023). The Potential for Introduction (propagule pressure and connectivity), the Potential for Establishment (habitat suitability, including a Calcium-based and Maximum Entropy (MaxEnt)-based model), the Potential for Invasion, and the Ecological Impacts were used to derive Ecological Risk for Zebra and Quagga Mussels in Canada. This assessment did not evaluate the risk to individual waterbodies but rather was conducted at a 9,260 m x 9,260 m grid cell resolution. These high resolution maps are provided here. Maps of Ecological Risk at the sub-drainage level are also provided.

CDC Species of Conservation Concern
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) .

Biodiversity Risk
The data represents an assessment of biodiversity risk for the agricultural area of Alberta in 2002. Biodiversity risk refers to the loss of biological diversity, or the variety of plant and animal life in agricultural landscapes. This map, created in ArcGIS, tries to show where biodiversity could be threatened, such as in areas with significant habitat that coincide with areas of greater agricultural economic activity. Biodiversity is believed to affect the overall health of the environment.
