Provincial Fish Ranges - Generalized
This file contains a generalized representation of watersheds developed from the 1:50,000 BC Watershed Atlas with each region coded for occurrence of freshwater fish species (including anadromous salmon in their freshwater stages). The initial fish species codes for presence/absence in each watershed were derived from an GIS overlay of fish species occurrences within broadly defined fish regions for BC. This overlay of fish ranges describes the occurrences of fish species in 30 regions throughout the province. These broad species ranges were derived from McPhail and Carveth's 'Key to Freshwater Fish of BC' and refined further based on the most current expert opinion. Coding for watershed polygons based on this expert opinion was originally: 0= out of species range; 4 = core range; 5= introduced range; 6= peripheral range; 9= estuarine polygons only. A further refinement of watershed fish species coding was developed from actual observations of fish species in the lakes and rivers of British Columbia. This data comes from a number of fish inventory sources. Watersheds with known records of occurrence for each fish species were consequently recoded as such: 4, 5, 6, 9 now equal '1' if a museum record, and, 4, 5, 6, 9 now equal '2' for a less reliable record, and, 0 now equals '8'. for an out-of range record

1M Base Map plus Fish and Wildlife Districts, Green/White Area - Provincial Base Map Series
공공데이터포털
This cartographic quality series of 1:1 000 000 scale colour maps cover the provincial extent of Alberta. The primary provincial base map displays the Alberta Township System (ATS), major hydrographic features, municipalities, major roads, railways and select geoadministrative features (parks, reserves, etc.). In addition to the primary provincial base map, this series includes various themes that overlay the primary base map. Each individual map sheet is provided in Adobe .pdf format.

2M Base Map plus Fish and Wildlife Districts, Green/White Area - Provincial Base Map Series
공공데이터포털
This cartographic quality series of printable 1:2 000 000 scale colour maps cover the provincial extent of Alberta. The 1:2 000 000 scale maps are a generalized small scale version of the 1:1 000 000 scale map. The primary provincial base map displays the Alberta Township System (ATS), major hydrographic features, municipalities, major roads, and select geo-administrative features (parks, reserves, etc.). In addition to the primary provincial base map, this series includes various themes that overlay the primary base map. Refer to the 'time period of content' in the metadata record for currency of each map product. Each individual map sheet is provided in Adobe .pdf format. This series is generally updated on an annual basis.

Habitat and fish assemblages along four river mainstems in Ontario, Canada, 1997 to 2001, with supporting spatial data
공공데이터포털
This dataset includes information about valley segment and catchment summaries, valley characteristics, instream habitat, and fish for valley segments, sites, and transects along four river mainstems in Ontario, Canada. Moving west to east, the rivers include the Grand River which ends in Lake Erie at Port Maitland, the Ganaraska River which ends in Lake Ontario at Port Hope, the Trent River which ends in the Bay of Quinte at Trenton, and the Petawawa River which ends in the Ottawa River at Petawawa. These rivers vary in natural character, anthropogenic development, and fish assemblages. Riverine sites along the mainstems of all four rivers included a total of one hundred and twelve sites. Sampling on the Grand, Trent, and Petawawa Rivers focused on non-wadeable lower river mainstems, whereas all sites on the Ganaraska River mainstem were wadeable and incorporated a wider range of stream sizes. Sites were sampled between 1997 and 2001, with many sites sampled in multiple years. The study design for the Grand, Trent, and Petawawa Rivers include a hierarchical design where data collection was nested at three spatial scales -- shoreline and channel transect data are nested within sites, and sites are nested within valley segments. In the Ganaraska River, data collection was by site and nested within valley segments. A complementary set of shapefiles for each river supports these tabular data and provides items needed to map watersheds, valley segments, and sites, and to calculate additional variables for sites and site catchments. The metadata specific to these spatial data is associated with the shapefiles and is not described here.
