Salmon River Watershed Fish Distribution and Stream Classification Modeling, Prince George, BC

In order to meet obligations under the Forest and Range Practices Act (FRPA), forestry planners need to know both the fish distribution and stream width in streams adjacent to cutblocks or to be crossed by new access roads. The Fish and Fish Habitat Assessment Tool (FHAT20) computer model was developed by the BC Ministry of Environment to assist resource planners by providing a tool that helps to interpret reconnaissance inventory data and extrapolate this information to un-sampled stream reaches. Canadian Forest Products, Prince George, retained EDI to run portions of their Salmon River operating areas through the FHAT20 model. The model output can be used to establish Forest and Range Practices Act (FRPA) stream class and to identify areas of uncertainty in fish distribution or stream width. This information helps to prioritize field work, improve management decisions, and assist in watershed level resource planning.


Design and Implementation Assistance for Stream Classification Local Area Agreement (LAA) Herrick Creek, Prince George, BC

EDI's GIS staff and professional biologists assisted Canfor (formerly Northwood) with the design and implementation of two Local Area Agreements with respect to stream classification under the BC Forest Practices Code for the Herrick Creek operating area. Detailed fish and fish habitat data collected for specific geographical areas were assessed to create a predictive model for fish presence. Liaison with both the BC Ministry of Environment and Fisheries and Oceans Canada (DFO) staff was a major component of this project.

Mapping of Radio Tagged Arctic Grayling, north central BC

EDI was retained by the BC Ministry of Environment and the Peace/Williston Compensation Program to map digital data from radio-tagged Arctic grayling being monitored within the Williston Reservoir watershed. Thematic maps depicted individual fish movement along with tagging, overwintering and spawning locations.

Fish and Fish Habitat Compilation for Champagne and Aishihik Non-Overlap Areas, Yukon

EDI completed a detailed fisheries research and GIS mapping project within the non-overlap areas of the Champagne and Aishihik Traditional Territory in the Yukon. This project included mapping of known fish species distribution, interpretation of fish values, and identification of data gaps for future sampling.

Juvenile Chinook Mapping, Yukon River Drainage

EDI compiled and mapped juvenile chinook salmon distribution throughout the Canadian portion of the Yukon River watershed. Point data on capture locations of juvenile chinook were mapped for areas outside the known spawning distribution.
