... Cizek Environmental Services was contracted ... to complete the following tasks .... Task # 1: .... A regional map showing a study area of approximately 100 km by 100 km around Fort Liard would be prepared at a scale of approximately 1:1 Million. This map would incorporate the following data sources: 1. All weather and seasonal roads, 2. Hydrology, 3. Topography, 4. Land Use Permits and Surface Dispositions, 5. Oil and Gas Rights, 6. Well Sites, 7. NEB Historic Seismic Lines (1958-1992) and Cut-Lines (from 1:250,000 National Topographic Series), 8. Pipelines. Many ... of these data such as roads, seismic lines, and forestry activities would have to be updated by accessing land use permit records and manually digitizing features. The map would include as much detail as possible for all the activities. A table summarizing the activities by type, number, time period, and physical footprint would also be produced. Task #2: ....
Small-scale vertical aerial photography (1:20,000 to 1:50,000) covering approximately 10 km x 10 km would be obtained for a detailed study area such as the Pointed Mountain gas field. Depending on availability, air photographs showing the following phases would be obtained: a) No industrial activity (pre-1960), b) Exploration (1960-70), c) Beginning of Production (1970-1980), d) Recent Status (1980-2001). The air photographs would be scanned to produce high-resolution graphic images, interpreted, and annotated to depict changes in the types of industrial activities. Task #3: .... The recently developed United Nations Environment Program ... "Global Methodology for Mapping Human Impacts on the Biosphere" (GLOBIO) ... has been applied to the circumpolar Arctic. Based on a literature review of over 600 scientific field studies, GLOBIO has approximated the spatial impact of industrial development in Arctic regions within the following categories: 1)
Reduced survival and/or abundance of birds (0-l km from infrastructure), 2) Reduced survival and/or abundance of large mammals (0-3 km), 3) Cumulative effects on flora and fauna, including shifts in insect composition, food chains, hydrology, predation patterns, etc. (0-20 km), 4) Areas with no disturbance (>20 km). The GLOBIO methodology would be applied to the existing regional map prepared under Task#1 to determine the current spatial impact of industrial activities on the study area. A map showing the impact zones, including overlaps in impact zones from multiple activities, would be produced. Using the summary data table of current industrial activities prepared under Task #1, a forecast of possible activities would be prepared for the years 2010 and 2050 resulting in two additional maps. ... application of the GLOBIO methodology is a relatively quick and inexpensive method for broad-level and generalized cumulative impact assessment in a
small region of the NWT. The speed and simplicity of this approach also makes it useful for strategic planning and scenario-building. ... This study's most important finding is that current and future forecast cumulative impacts of seismic exploration are likely far greater than the cumulative impacts of actual hydrocarbon production itself. The possible extent of all impacts underlines the need for NWT agencies to quickly establish a cumulative effects assessment framework (including thresholds and limits of acceptable change), land use planning, and a representative network of protected areas. Specific recommendations are presented in the areas of data management, study refinement, and directions for further research. ...
