EAU BC is a hierarchical classification of BC's freshwater ecosystems. It is a spatially explicit classification designed to aid in the management and conservation of BC freshwater ecosystems and their associated biodiversity. EAU BC quantifies the interplay between freshwater species distribution and their ecosystem physical habitat, and environmental processes. It defines what is currently known about freshwater ecosystems and their abundance and distribution across the Province. It is packaged as a database and accompanying geographic information system (GIS) that enables the classification and its underlying data to be queried and viewed at multiple spatial scales. Available EAUBC GIS data include EAUBC Freshwater...

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 dervied 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...

This is a provincial coverage of stream macro-reaches. A macro-reach is a homogeneous stream segment delineated through interpretation of reach attributes from the 1:50,000 National Topographic Series (NTS) of mapsheets. Reach attributes include gradient (as derived from contour interpolation), channel pattern, size of stream, order of stream, major falls, position of the stream in the landscape, and inferred bank materials. These macro-reaches are geo-referenced to the stream centreline network of the BC Watershed Atlas 50K. Each stream is subdivided into one or more macro-reaches that run in a continuous sequence from a stream's mouth to its headwaters. This theme has been used to quantify some aspects of hydrology...

Wildlife radio-telemetry may be defined as the transmission of information from a transmitter on a free-ranging wild animal to a receiver. Wildlife-related telemetry is also known as radio tagging, radio-tracking or simply ?tagging? or ?tracking?. Advances in the field of wildlife telemetry have made it possible to acquire detailed data on many aspects of wildlife biology, including habitat use, home range size, mortality and survivorship, and migration timing and routes.Since many wildlife species are secretive and difficult to observe, radiotelemetry has provided a valuable tool to learn more about their respective life histories

This is a provincial coverage of inland waters fish species distribution, mapped as points. These fish points are geo-referenced to the stream centreline network of the BC Watershed Atlas 50K digital map base. This theme is based on data from the Fisheries Information Summary System (FISS) database that was compiled prior to the year 2000. Each point represents either a specific site where a fish species has been identified or the point represents a whole stream in which the fish species is known to be present. These latter whole stream points are always located at the stream mouth. Fish point attributes include the fish species name, and where known, the stock type and the spawning, rearing or holding activity...
